Parameters

value: Specifies a DED priority value in the range of 0 to 127.

Usage guidelines

The edge devices on an EVI link exchange their DED priority in EVI IS-IS hello packets to elect an inter-site DED for periodic LSDB synchronization. You can use the evi isis timer csnp command to change the synchronization interval.

The edge device with higher DED priority is more likely to be elected as an inter-site DED. If two edge devices have the same DED priority, the one with the highest MAC address is elected.

Parameters

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

Usage guidelines

Adjacency hold time is the amount of time that the remote edge devices can retain the adjacency with the local edge device before an adjacency update.

· If Graceful Restart is disabled, the adjacency hold time equals the EVI IS-IS hello interval multiplied by the hello multiplier.

· If Graceful Restart is enabled, the adjacency hold time equals the greater of the following values:

¡ The restart interval.

¡ The EVI IS-IS hello interval multiplied by the hello multiplier.

Edge devices send their adjacency hold time in hello packets to update the adjacencies with their neighbors. An edge device removes the adjacency with a neighbor if it does not receive a hello packet from the neighbor before the timer expires.

The maximum adjacency hold time is 65535 seconds. If this value is exceeded, the actual adjacency hold time is set to 65535 seconds.

Examples

# Set the multiplier for calculating EVI IS-IS adjacency hold time to 6.

simple: Specifies an authentication key in plaintext form.

password: Specifies the authentication key. Its plaintext form is a case-sensitive string of 1 to 24 characters in length. Its encrypted form is a case-sensitive string of 1 to 65 characters.

Usage guidelines

Configure ENDP authentication in an insecure network to prevent malicious registration with an ENDS.

Make sure all authentication-enabled ENDCs and ENDSs in an EVI network use the same authentication key.

If authentication is disabled on an ENDS, all ENDCs, including authentication-enabled ENDCs, can register with the ENDS without authentication.

If authentication is enabled on an ENDS, only authentication-enabled ENDCs that use the same authentication key as the ENDS can register with the ENDS.

Parameters

server-ip: Specifies the IP address of a remote ENDS-enabled EVI tunnel interface.

Usage guidelines

For redundancy, you can configure up to two ENDS addresses on an EVI tunnel interface. These two ENDSs work independently. The failure of one ENDS does not affect the neighbor discovery and EVI link maintenance in the EVI network.

On an ENDS-enabled EVI tunnel interface, you can use the evi neighbor-discovery client enable command to add only one ENDS address. An ENDS is always an ENDC of itself. When you enable ENDS on an EVI tunnel interface, an ENDC is automatically enabled, with the source address of the EVI tunnel as the ENDS address.

To guarantee that each edge device can obtain the addresses of all its EVI neighbors, make sure the ENDSs are the same across the EVI network.

Examples

# Configure Tunnel 0 as an ENDC of the ENDS at 11.0.0.1.

Views

Tunnel interface view

Predefined user roles

mdc-admin

Parameters

time-value: Specifies a registration update interval in the range of 5 to 120 seconds.

Usage guidelines

ENDP uses an ENDS probe timer and a registration aging timer in addition to the ENDC register timer set with this command.

· ENDS probe timer—Sets the interval for an ENDC to detect an ENDS. This timer is maintained on ENDCs and is not user configurable.

· ENDC register timer—Sets the interval for an ENDC to update its registration with an ENDS. This timer is by default 15 seconds and can be changed with the evi neighbor-discovery client register-interval command on ENDCs.

· Registration aging timer—This timer is five times the ENDC register timer. This timer is maintained on ENDSs. When the registration aging timer for an ENDC expires, ENDS removes the ENDC from its ENDC database.

When an ENDC sends a register request to join the EVI network, a 5-second ENDS probe timer starts. The ENDC sends a register request to the ENDS every 5 seconds until it receives a response from the ENDS.

When the ENDC receives a response from the ENDS, the ENDS probe timer stops and an ENDC register timer starts. The ENDC regularly sends register updates at the interval set by the register timer.

If the ENDC does not receive a response after sending five consecutive register packets, the ENDC clears its neighbor information database and starts the ENDS probe timer.

The ENDC adds the register timer setting to each register packet. The ENDS records this timer setting when it adds the ENDC to the ENDC database. If no register update is received from the ENDC before five times the timer is reached, ENDS removes the ENDC from the EVI network.

Examples

# Set the ENDC registration update interval to 30 seconds on the EVI tunnel interface Tunnel 0.

Parameters

mac-address: Specifies a MAC address, which cannot be all Fs.

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

Usage guidelines

CAUTION:

Do not configure selective flood for a unicast MAC address that might be learned at an edge device's data plane. The configuration can cause packets destined for the MAC address to be dropped on remote devices after they obtain the MAC address entry through EVI IS-IS.

By default, the device floods unknown unicast and multicast frames only to internal interfaces.

The device floods a destination unknown frame to an EVI tunnel interface if the frame's destination MAC address and VLAN ID match a selective flood entry.

Enable selective flood for special multicast addresses that require flooding across sites but cannot be added to a multicast forwarding table by IGMP snooping.

Examples

# Configure selective flood for 000f-e201-0101 in VLANs 1 to 10 on the EVI tunnel interface Tunnel 101.

Parameters

site-id: Specifies a site ID in the range of 1 to 65535.

Usage guidelines

By default, all edge devices in an EVI network have a site ID of 0. To identify the site of each edge device, you can change their site IDs.

Manually assigned site IDs must be unique in the EVI network. If the edge devices at two sites are assigned the same site ID, EVI IS-IS isolates the device with the lower MAC address. The isolated device can only receive EVI IS-IS hello packets. It cannot exchange EVI IS-IS packets with its neighbors. To identify isolated devices, use the display evi isis brief command or the display evi isis peer command.

NOTE:

EVI IS-IS does not perform isolation for edge devices that use the default site ID.

Examples

evi-isis

Use evi-isis to create an EVI IS-IS process or enter EVI IS-IS process view.

Use undo evi-isis to delete an EVI IS-IS process or clear the configuration that has made in EVI IS-IS process view.

Syntax

evi-isis process-id

undo evi-isis process-id

Default

No EVI IS-IS process exists.

Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

process-id: Specifies an EVI IS-IS process ID in the range of 0 to 65535.

Usage guidelines

Each EVI network has one EVI IS-IS process. Before you can configure settings in EVI IS-IS process view, you must create the process.

An EVI IS-IS process is created automatically when you perform any one of the following tasks on a tunnel interface:

· Specify extended VLANs.

· Perform network optimization tasks (see EVI Configuration Guide) except configuring the EVI IS-IS hello interval and the maximum LSP lifetime.

The ID of an automatically created process is the same as the EVI tunnel interface number.

Alternatively, you can use the evi-isis command to create an EVI IS-IS process manually.

To delete a manually created EVI IS-IS process, you must use the undo evi-isis command.

· If EVI IS-IS settings exist on the EVI tunnel interface, the undo evi-isis command only deletes settings configured in EVI IS-IS process view.

· If no EVI IS-IS settings exist on the EVI tunnel interface, the undo evi-isis command deletes both the EVI IS-IS process and all settings configured in EVI IS-IS process view.

An automatically created EVI IS-IS process is automatically deleted when you delete all EVI IS-IS settings from the EVI tunnel interface.

Examples

# Enter EVI IS-IS process view.

keepalive

Use keepalive to configure the keepalive interval on an EVI tunnel interface and configure the maximum number of consecutive keepalive failures that are allowed before a remote end is declared unavailable.

Use undo keepalive to restore the default.

Syntax

keepalive [ seconds [ times ] ]

undo keepalive

Default

The EVI link keepalive interval is 5 seconds and the permitted maximum number of consecutive keepalive failures is two.

Views

Tunnel interface view

Predefined user roles

network-admin

mdc-admin

Parameters

seconds: Specifies a keepalive interval in the range of 1 to 32767 seconds.

times: Specifies the maximum number of consecutive keepalive failures in the range of 1 to 255.

Usage guidelines

The EVI-Link interfaces on an EVI tunnel regularly send keepalive packets to test the availability of their peer ends.

If no acknowledgement is received from the peer end before the timeout timer expires, an EVI-Link interface retransmits a keepalive packet. The timeout timer is the same as the keepalive interval.

When the maximum number of consecutive keepalive failures is reached, the EVI-Link interface state changes to Down. The EVI-Link interface state changes back to Up after the interface receives a keepalive acknowledgement or keepalive packet.

Examples

# Set the keepalive interval to 20 seconds and the maximum number of consecutive keepalive failures to 5.

<Sysname> system-view

[Sysname] interface tunnel 0 mode evi

[Sysname-Tunnel0] keepalive 20 5

snmp context-name

Use snmp context-name to configure an SNMP context for an EVI IS-IS process.

Use undo snmp context-name to restore the default.

Syntax

snmp context-name context-name

undo snmp context-name

Predefined user roles

network-admin

mdc-admin

Parameters

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

Usage guidelines

In addition to the private EVI IS-IS MIB, EVI IS-IS 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 eviisis100 for EVI IS-IS process 100.

<Sysname> system-view

[Sysname] evi-isis 100

[Sysname-evi-isis-100] snmp context-name eviisis100

snmp-agent trap enable evi-isis

Use snmp-agent trap enable evi-isis to enable EVI IS-IS notifications.

Use undo snmp-agent trap enable evi-isis to disable EVI IS-IS notifications.

lsp-parse-error: Specifies notifications about LSP parse failures.

lsp-size-exceeded: Specifies notifications about propagation failures caused by oversized LSPs.

max-seq-exceeded: Specifies notifications about attempts to exceed with the maximum LSP sequence number.

maxarea-mismatch: Specifies notifications about maximum area address mismatches of hello packets.

new-ded: Specifies notifications about the device's being elected as the DED.

own-lsp-purge: Specifies notifications about attempts to remove the local LSP.

protocol-support: Specifies notifications about supported-protocol mismatches for non-pseudo node LSPs.

rejected-adjacency: Specifies notifications about adjacency creation failures.

skip-sequence-number: Specifies notifications about LSP sequence number duplications.

topology-change: Specifies notifications about edge device topology changes at the local site. This notification will not be sent if a new-ded notification has been sent for the same vent.

version-skew: Specifies notifications about hello packet version mismatches.

Usage guidelines

If you do not specify a notification, this command enables all EVI IS-IS notifications.

To report critical EVI IS-IS events to an NMS, enable SNMP notifications for EVI IS-IS. For EVI IS-IS event notifications to be sent correctly, you must also configure SNMP as described in Network Management and Monitoring Configuration Guide.
