If AP is enabled, ISIS-SPB issues forwarding entries to the FIB tables in the data plane only if AP declares a topology match after LSDB synchronization is complete.

NOTE:

In this document, "AP" refers to agreement protocol. In other documents, "AP" can also refer to access points.

Examples

# Enable AP for multicast FDB entries.

[Sysname] spbm

[Sysname-spbm] ap-mode multicast

area-authentication send-only

Use area-authentication send-only to disable authentication for incoming ISIS-SPB topology advertisement packets (LSPs, CSNPs, and PSNPs).

Use undo area-authentication send-only to restore the default.

Syntax

area-authentication send-only

undo area-authentication send-only

Default

ISIS-SPB authenticates incoming topology advertisement packets if area authentication (area-authentication-mode) is configured. The device accepts a topology advertisement packet only if the authentication method and password in the packet match its local authentication settings.

Views

SPBM view

Predefined user roles

network-admin

Usage guidelines

Before you change area authentication settings for an SPBM network, configure this command to prevent temporary authentication setting mismatch from causing topology advertisement packets to be dropped.

For security purposes, restore the default to authenticate incoming topology advertisement packets after you change area authentication settings across the SPBM network.

This command does not affect outgoing topology advertisement packets. When area authentication is enabled, outgoing ISIS-SPB topology advertisement packets always contain authentication information.

Examples

# Disable authentication for incoming ISIS-SPB topology advertisement packets.

area-authentication-mode

Use area-authentication-mode to configure area authentication.

Use undo area-authentication-mode to restore the default.

Syntax

undo area-authentication-mode

Default

Area authentication is disabled. No area authentication method or password is configured.

Views

Predefined user roles

network-admin

Parameters

md5: Specifies MD5 authentication.

simple: Specifies simple authentication.

cipher: Specifies a password in encrypted form.

plain: Specifies a password in plaintext form. For security purposes, the password specified in plaintext form will be stored in encrypted form.

string: Specifies the password. The plaintext password is a case-sensitive string of 1 to 16 characters. The encrypted password is a case-sensitive string of 33 to 53 characters.

Usage guidelines

ISIS-SPB area authentication guarantees that SPBM nodes learn topology data only from trustworthy neighbors.

For correct authentication, make sure the authentication method and password are the same across the SPBM network. ISIS-SPB sends these authentication settings in topology advertisement packets (LSPs, CSNPs, and PSNPs). The recipients accept a topology advertisement packet only if the authentication settings in the packet match their local authentication settings.

Example

# Set the area authentication method to simple and the password to 123456 in plain text.

Parameters

value: Specifies a bandwidth reference in the range of 1 to 2147483648 Mbps.

Usage guidelines

ISIS-SPB automatically calculates a link metric value for an interface if both the global and interface-specific link metric values are not set.

The following is the calculation formula:

Link metric value=(Reference bandwidth/Interface rate)x10

The value range for the link metric value is 1 to 16777214.

To assign a link metric value to an interface, use one of the following methods:

· Set an interface-specific value in interface view.

· Set a global value in SPBM view. This global value applies to all SPBM-enabled interfaces.

· Set a bandwidth reference for the system to calculate a value automatically for the interface.

The system chooses a link metric value for an interface in order of interface-specific value, global value, and autocalculated value.

Table 14 Command output

Field	Description
Restart status	Restart state of the device: · Restarting—The device is rebooting ISIS-SPB or performing an active/standby MPU switchover. In this state, the device can forward traffic because its FIB is usable. · Starting—The device is rebooting. In this state, the device cannot forward traffic because the FIB is not usable. · Complete—The GR process is complete. The device can forward traffic.
Restart phase	Restart phase: · Initialization—ISIS-SPB Graceful Restart is initialized. · LSDB synchronization—Peer ISIS-SPB processes are synchronizing LSDBs. · LSP stability—The local LSDB is converging. · LSP generation—ISIS-SPB generates and floods LSPs. · First SPF computation—ISIS-SPB performs the first SPF computation. · Finish—SPF computation is finished.
Restart Interval	The maximum adjacency hold time (in seconds). If the restarting device fails to complete restarting before this timer expires, the peer ISIS-SPB process removes the adjacency with the restarting ISIS-SPB. This timer is configurable with the graceful-restart t2 command.
SA bit	Support for setting the SA bit in the Restart TLV sent to the neighbor: · Supported—The device performs the following actions: ¡ When the FIB is not usable, the device sets the SA bit in the hello messages so the neighbor will not advertise its adjacency with the restarting device. ¡ When the routing table is usable, the device clears the SA bit in the hello messages so the neighbor will advertise its adjacency with the restarting device. · Not supported—The device clears the SA bit in the hello messages so the neighbor will always advertise its adjacency with the restarting device.
Total number of interfaces	Number of SPBM-enabled interfaces.
Number of waiting LSPs	Number of LSPs that are waiting to be synchronized with the GR helper for completing LSDB synchronization.
T2 remaining time	The remaining time (in seconds) of the T2 timer. If the restarting device fails to complete restarting before this timer expires, the neighbor removes the adjacency with the restarting device.
T1 remaining time	Remaining time (in seconds) of the T1 timer on the interface. The T1 timer sets the interval for the restarting device to retransmit hello messages with the RR bit set (restart request messages). The T1 timer is not user configurable. The restarting device retransmits a restart request message to the neighbor if it does not receive an acknowledgment for a restart request (hello message with the RA bit set) before the T1 timer expires.
RA received	Whether the interface received an ISIS-SPB hello with the RA flag from the neighbor device.
CSNP received	Whether the interface received a CSNP from the neighbor device.
T1 expirations	Number of T1 timer expirations on the interface. When this counter reaches 10, the restarting device stops retransmitting hello messages with the RR bit set.

ect

Use ect to map an ECT algorithm to a list of B-VLANs.

Use undo ect to remove ECT algorithm and B-VLAN mappings.

Syntax

ect ect-index b-vlan vlan-id-list

undo ect ect-index b-vlan [ vlan-id-list ]

Default

All B-VLANs are mapped to ECT 1.

Views

SPBM view

Predefined user roles

network-admin

Parameters

ect-index: Specifies an ECT algorithm index in the range of 1 to 16.

vlan-id-list: Specifies a space-separated list of up to 10 B-VLAN items. Each item specifies a B-VLAN ID or a range of B-VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for B-VLAN IDs is 1 to 4094. The ID for vlan-id2 must be equal to or greater than the ID for vlan-id1.

Usage guidelines

An ECT algorithm represents a set of tie-breakers for calculating SPTs.

To improve link efficiency in an SPBM network, you can distribute traffic of B-VLANs along different paths by mapping B-VLANs to different ECT algorithms.

To ensure correct SPT calculation for a B-VLAN, the B-VLAN to ECT algorithm mappings must be the same across the SPBM network for B-VLANs that are in use. If two neighbors map a B-VLAN to different ECT algorithms, the link between them cannot transmit data traffic for the B-VLAN.

You cannot remove the mappings between ECT algorithm 1 and B-VLANs. The undo ect command does not take effect if you specify ECT algorithm 1 in the command.

Examples

# Map B-VLAN 100 through B-VLAN 200 to ECT 2.

<Sysname> system-view

[Sysname] spbm

[Sysname-spbm] ect 2 b-vlan 100 to 200

undo flash-flood

Default

Fast flooding of LSPs is disabled.

Views

SPBM view

Predefined user roles

network-admin

Parameters

flood-count flooding-count: Specifies the maximum number of LSPs that can be rapidly flooded before SPF computation is started. The value range for the flooding-count argument is 1 to 15. The default value is 5.

max-timer-interval interval: Specifies the delay before fast flooding is performed. The value range for the interval argument is 10 to 50000 milliseconds. The default value is 10.

Usage guidelines

Fast flooding of LSPs enables ISIS-SPB to flood the specified number of LSPs that invoke SPF before SPF computation is started. This mechanism improves ISIS-SPB convergence time.

Usage guidelines

Setting the SA bit prevents the neighbor from advertising the ISIS-SPB adjacency with the GR restarter. This command prevents route blackholes by temporarily excluding the restarter from the SPF computation on other SPBM nodes.

If the SA bit is not set, the ISIS-SPB neighbors advertise the adjacency with the device while the device is restarting.

Parameters

is-name: Assigns a hostname to the device, a case-sensitive string of 1 to 64 characters.

Usage guidelines

ISIS-SPB uses a 6-byte system ID to represent a node in the network. This type of system ID is difficult for administrators to identify devices when they examine ISIS-SPB adjacencies, FDB entries, and LSDB entries.

Dynamic hostname exchange enables you to assign a symbolic hostname to each SPBM node. ISIS-SPB advertises this information in the Dynamic hostname TLV in LSPs to remote LSDBs.

Predefined user roles

network-admin

Parameters

on-startup: Sets the overload bit when the system starts up.

start-from-nbr system-id [ timeout1 [ nbr-timeout ] ]: Sets the timers for controlling the overload bit state during the process of adjacency establishment. The nbr-timeout timer starts when the device starts up. If the device fails to establish an adjacency with the neighbor identified by system-id before the timer expires, the overload bit is cleared. If adjacency establishment is complete before the timer expires, the timeout1 timer starts. The overload bit is set before the timeout1 timer expires. When the timeout1 timer expires, the overload bit is cleared.

· system-id: Specifies a neighbor by its system ID in XXXX.XXXX.XXXX format.

· timeout1: Sets the delay to clear the overload bit, in the range of 5 to 86400 seconds. The default value is 600 seconds.

· nbr-timeout: Sets the adjacency setup timer in the range of 5 to 86400 seconds. The default value is 1200 seconds.

timeout2: Specifies the amount of time for the overload bit to be set since the system startup. The value range for this argument is 5 to 86400 seconds. The default is 600 seconds.

Usage guidelines

ISIS-SPB sets the overload bit in LSPs to notify its neighbors that it is experiencing an LSDB error condition and cannot forward traffic correctly. During path calculation, ISIS-SPB does not choose a path as the shortest path if the path includes the device that has the overload bit set.

You can set the LSDB overload bit when the device cannot record complete topology data in the LSDB for insufficient memory or any other problems.

If you do not specify any parameters, the command sets the overload bit immediately. To clear the overload bit, you must use the undo set-overload command.

Default

No SNMP context is configured for ISIS-SPB.

Views

SPBM view

Predefined user roles

network-admin

Parameters

context-name: Specify a context name, a case-sensitive string of 1 to 32 characters.

Usage guidelines

ISIS-SPB shares the standard IS-IS MIB with IS-IS and other protocols that use IS-IS in the control plane. For SNMP to correctly identify a protocol's management information in the standard IS-IS MIB, you must configure a unique context for each of these protocols. If a protocol supports multiple processes, you must assign a unique context to each process.

The context names must be unique among all the protocols and their processes.

Context is a method introduced to SNMPv3 for multiple instance managements. For SNMPv1/v2c, you must specify a context name as a community name for protocol identification.

Examples

# Configure the SNMP context name as spbm for ISIS-SPB.

Parameters

i-sid: Specifies an I-SID for the VSI, in the range of 255 to 16777215.

Usage guidelines

You must assign a unique I-SID to each SPB VSI for identification. The name of an SPB VSI can be different on different SPBM nodes, but its I-SID must be the same across an SPBM network. For more information about VSIs, see MPLS Configuration Guide.

You can configure one SPB I-SID and one PBB I-SID for a VSI, but the two I-SIDs cannot be the same. For more information about PBB, see Layer 2—LAN Switching Configuration Guide.

The I-SID for the fast-channel VSI is 255. The fast channel feature provides a quicker LSP propagation method than conventional LSP propagation. To use the fast-channel feature, you must create a VSI and assign I-SID 255 to the VSI. You cannot associate any Ethernet service instance with the VSI that uses I-SID 255 for data transmission.

Parameters

md5: Specifies MD5 authentication.

simple: Specifies simple authentication.

cipher: Specifies a password in encrypted form.

plain: Specifies a password in plaintext form. For security purposes, the password specified in plaintext form will be stored in encrypted form.

string: Specifies the password. The plaintext password is a case-sensitive string of 1 to 16 characters. The encrypted password is a case-sensitive string of 33 to 53 characters.

Usage guidelines

ISIS-SPB adjacency authentication guarantees that SPBM nodes establish adjacencies only with trustworthy neighbors.

For correct authentication, make sure the authentication method and password are the same between SPBM neighbors. ISIS-SPB sends these authentication settings in hello packets. The recipients accept a hello packet only if the authentication settings in the packet match their local authentication settings.

Parameters

cost-value: Specifies a link metric value in the range of 1 to 16777215. If the link metric is set to 16777215, the link will not be used for transmitting data traffic even if the adjacency can be established and the link is up.

Usage guidelines

To assign a link metric value to an interface, use one of the following methods:

· Set an interface-specific value in interface view.

· Set a global value in SPBM view. This global value applies to all SPBM-enabled interfaces.

· Set a bandwidth reference for the system to calculate a value automatically for the interface.

The system chooses a link metric value for an interface in order of interface-specific value, global value, and autocalculated value.

Parameters

seconds: Specifies an interval in the range of 3 to 255 seconds.

Usage guidelines

ISIS-SPB sends hellos over links to establish and maintain adjacencies between SPBM nodes.

A short interval improves network convergence time, but it requires more system resources.

The maximum adjacency hold time is 65535 seconds. If this value is exceeded, the original hello interval remains unchanged.

Predefined user roles

network-admin

Parameters

value: Specifies a multiplier in the range of 3 to 1000.

Usage guidelines

Adjacency hold time specifies the amount of time for one SPBM node to retain the adjacency with another. This timer determines how quick it takes for an SPBM node to detect a failed link.

The adjacency hold time equals the hello interval multiplied by the hello multiplier.

An SPBM node sends its adjacency hold time in hello packets to update the adjacencies with its neighbor. The neighbor removes the adjacency with the advertising node and recalculates routes if it does not receive a hello packet before the timer expires.

The maximum adjacency hold time is 65535 seconds. If this value is exceeded, the original hello multiplier remains unchanged.

Examples

# Set the hello multiplier to 6 on Ten-GigabitEthernet 1/0/1.

Usage guidelines

To control ISIS-SPB traffic on a circuit, set the minimum interval for the device to transmit LSPs out of the circuit and the maximum number of LSPs sent at each interval.

As a best practice, set a large minimum LSP transmit interval to prevent LSP storms in a network that contains a large number of provider network ports or routes.

Parameters

maximum-interval: Specifies the maximum LSP generation interval in the range of 1 to 120 seconds.

minimum-interval: Specifies the minimum LSP generation interval in the range of 10 to 60000 milliseconds. This setting must be smaller than the maximum interval.

incremental-interval: Specifies the base number for the incremental interval. The value range is 10 to 60000 milliseconds. This setting must be smaller than the maximum interval.

Usage guidelines

The LSP generation timer sets the delay for ISIS-SPB to generate a new version of an LSP in response to an LSP change. For example, an update occurs because of a change in adjacency, interface metric value, system ID, or area address.

The LSP generation timer is an exponential generation timer. With this timer, ISIS-SPB quickly responds to the first events for an LSP and then slows down to protect the CPU from frequent LSP generation.

When the network is stable, the LSP generation timer is set to the minimum interval for each LSP generation. When the network is unstable, the LSP generation timer increments by incremental-interval×2n-2 (n is the number of generation times) for each LSP generation until the maximum interval is reached. If an event triggers LSP generation after the maximum interval is reached, the LSP generation timer re-initiates with the minimum interval.

The network is considered unstable if the interval between consecutive LSP generation events is smaller than two times the maximum interval.

Examples

# Set the maximum LSP generation interval, the minimum LSP generation interval, and the base number for the incremental interval to 10 seconds, 100 milliseconds, 200 milliseconds, respectively.

Parameters

seconds: Specifies the maximum LSP lifetime in the range of 1 to 65535 seconds.

Usage guidelines

This command specifies the maximum amount of time for an LSP generated by the device to be retained in an LSDB.

SPBM nodes add a lifetime in each LSP they have advertised. If an SPBM node does not receive an update for an LSP before its lifetime expires, the SPBM node performs the following actions:

· Removes the LSP from the LSDB.

· Retains the LSP digest for 60 seconds.

· Floods an update of the LSP with a lifetime of 0. The SPBM neighbors remove the LSP from their LSDBs when they receive the LSP update.

To prevent unnecessary LSP age-outs, increase the LSP lifetime on a slow network.

Examples

# Set the maximum LSP lifetime to 1500 seconds.

Parameters

seconds: Specifies the LSP refresh interval in the range of 1 to 65534 seconds.

Usage guidelines

To prevent LSPs from age-out and synchronize LSDBs, ISIS-SPB performs periodic LSP update. The LSP refresh interval sets the interval at which ISIS-SPB regularly regenerates an LSP, regardless of whether any change has occurred to the LSP.

A short refresh interval improves network convergence time, but it also uses more bandwidth resources and system resources.

To avoid unnecessary LSP age-outs, make sure the LSP refresh interval is shorter than the LSP lifetime.

Examples

# Set the LSP refresh interval to 1200 seconds.

Parameters

maximum-interval: Specifies the maximum SPF computation interval in the range of 1 to 120 seconds.

minimum-interval: Specifies the minimum SPF computation interval in the range of 10 to 60000 milliseconds. This setting must be smaller than the maximum interval.

incremental-interval: Specifies the base number for the incremental interval, in the range of 10 to 60000 milliseconds. This setting must be smaller than the maximum interval.

Usage guidelines

The SPF calculation timer sets the delay between consecutive SPF calculations. You can increase the timer for ISIS-SPB to react quickly to topology changes, and decrease the timer to protect the CPU from frequent SPF calculations.

The SPF timer is an exponential generation timer. With this timer, ISIS-SPB quickly responds to the first events that trigger SPF calculation and then slows down to protect the CPU from frequent SPF calculations.

When the network is stable, the SPF calculation timer is set to the minimum interval for each SPF computation. When the network is unstable, the SPF calculation timer increments by incremental-interval×2n-2 (n is the number of calculations) for each SPF calculation until the maximum interval is reached. If an event triggers SPF calculation after the maximum interval is reached, the SPF calculation timer re-initiates with the minimum interval.

The network is considered unstable if the interval between consecutive SPF calculations is smaller than two times the maximum interval.

Examples

# Set the maximum SPF computation interval, the minimum SPF computation interval, and the base number for the incremental interval to 10 seconds, 100 milliseconds, and 300 milliseconds, respectively.
