Usage guidelines
Use ARP flood suppression to reduce ARP request broadcasts on the EVI network.
This feature snoops ARP replies on an EVI tunnel interface to populate the ARP flood suppression table with remote MAC addresses. If an ARP request has a matching entry, the edge device replies to the request on behalf of the remote-site host. If no match is found, the edge device floods the request to the EVI network.
To view the MAC aging timer value, use the display mac-address aging-time command. To configure the timer, use the mac-address timer command.

Parameters
vlan-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
If the site has more than one edge device in the EVI network, the EVI tunnel extends only active extended VLANs to remote sites.
Examples
# Specify extended VLANs 1 to 10, 15, and 100 to 200 on the EVI tunnel interface Tunnel 101.
<Sysname> system-view
[Sysname] interface tunnel 101 mode evi

evi flooding enable
Use evi flooding enable to enable EVI flooding for all destination-unknown frames.
Use undo evi flooding enable to disable EVI flooding.
Syntax
evi flooding enable
undo evi flooding enable
Default
EVI flooding is disabled. The device floods unknown unicast and multicast frames only to internal interfaces.
Views
Tunnel interface view
Predefined user roles
network-admin
Usage guidelines
EVI flooding enables the device to flood all destination-unknown frames to an EVI tunnel interface.
If selective flooding is also enabled for a MAC address in a list of VLANs, EVI flooding has higher priority than the selective flooding setting. The device will flood frames destined for that MAC address, whether or not the frames are from a VLAN in the VLAN list for selective flooding.
As a best practice, do not configure both the evi flooding enable command and the evi selective-flooding mac-address command.
Examples
# Enable EVI flooding on Tunnel 101.
<Sysname> system-view
[Sysname] interface tunnel 101 mode evi
[Sysname-tunnel 101] evi flooding enable

Default
The DED priority value is 64.
Views
Tunnel interface view
Predefined user roles
network-admin
Parameters
priority: Specifies a DED priority value in the range of 0 to 127.
Usage guidelines
DEDs include site DEDs and inter-site DEDs.
An inter-site DED is elected from between the edge devices on each EVI link to send CSNP packets for LSDB synchronization.
A site DED is elected from among the redundant edge devices at a multihomed site to distribute extended VLANs among them so the traffic of a VLAN always enters or leaves the site from the same edge device.
The edge devices on an EVI link exchange their DED priority in EVI IS-IS hello packets to elect the inter-site DED for periodic LSDB synchronization.
The edge devices at a multihomed site exchange their DED priority in EVI IS-IS hello packets to elect the site DED for distributing extended VLANs among them.
The edge device with higher DED priority is more likely to be elected as a site DED or inter-site DED. If two edge devices have the same DED priority, the one with the highest MAC address is elected.
Examples
# Set the DED priority value of Tunnel 101 to 2.

Predefined user roles
network-admin
Parameters
vlan-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
You can repeat this command to add preferred VLANs. For a preferred VLAN to take effect, you must make sure it has been specified as an extended VLAN.
At a dual-homed site, specify an extended VLAN as a preferred VLAN on the edge device you prefer to use as the appointed forwarder for the VLAN. The DED assigns an edge device its preferred VLANs as long as possible. If an extended VLAN is configured as a preferred VLAN on both edge devices, the DED uses the typical VLAN distribution rules to distribute the VLAN. For information about typical extended VLAN distribution, see multihoming in EVI Configuration Guide.
After you remove the preferred VLAN configuration on an edge device, the DED continues to assign the VLAN to the edge device if the following requirements are met:
· The EVI tunnel interface on the edge device is up.
· The VLAN has not been configured as a preferred VLAN on another edge device.
Examples
# Configure extended VLANs 1 to 10, 15, and 100 to 200 as preferred VLANs.

¡ 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 to 6 for calculating EVI IS-IS adjacency hold time.

Parameters
time: Specifies the minimum LSP transmit interval, a multiple of 100 in the range of 100 to 1000 milliseconds.
count count: Specifies the maximum number of LSP segments that can be sent at each interval. The value range is 1 to 1000.
Usage guidelines
The edge device generates an LSP update when any LSDB content changes. For example, an LSP update is generated when a MAC address is removed or added.
Use this command to control the number of LSP segments that the edge device sends out. To decrease the number of LSP segments, increase the interval and decrease the maximum number of LSP segments sent at each interval.

Parameters
track-entry-number: Specifies a track entry number in the range of 1 to 1024.
Usage guidelines
You can associate an EVI tunnel interface with only one track entry. If you execute this command multiple times, the most recent association takes effect.
EVI IS-IS uses a hello mechanism to monitor the connectivity of each EVI link on an EVI tunnel. To detect the connectivity of a particular EVI link more quickly, you can associate its tunnel interface with a track entry. The monitoring protocol used in this entry can only be BFD.
EVI IS-IS changes the state of an EVI-Link interface in response to the track entry state, as shown in Table 18.
Table 18 Action on the monitored EVI-Link in response to the track entry state change
Track entry state |
State of the monitored EVI link |
Action on the EVI-Link interface |
Positive |
The EVI link is operating correctly. |
Places the EVI-Link interface in up state. |
Negative |
The EVI link has failed. |
Places the EVI-Link interface in down state. |
NotReady |
The EVI link is not monitored. This situation occurs when the Track module or the monitoring module is not ready, for example, because the Track module is restarting or the monitoring settings are incomplete. In this situation, EVI cannot obtain information about the EVI link from the Track module. |
N/A |

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
network-admin
Parameters
interval: 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 by using 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 by using 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.

Default
Selective flooding is disabled for all MAC addresses. The device floods unknown unicast and multicast frames only to internal interfaces.
Views
Tunnel interface view
Predefined user roles
network-admin
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 flooding for a local unicast MAC address. The setting might cause remote devices to drop packets destined for that MAC address. |
The device floods a frame to an EVI tunnel interface if the frame meets all of the following conditions:
· The frame's destination MAC address and VLAN ID match a selective flooding entry.
· The VLAN is an active extended VLAN on the EVI tunnel interface.
Enable selective flooding for special multicast addresses that require flooding across sites but cannot be added to a multicast forwarding table by IGMP snooping.

Views
System view
Predefined user roles
network-admin
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 uniquely identify the sites in an EVI network, you can change their site IDs. To avoid site ID conflict, follow these guidelines when you configure site IDs:
· The edge devices at a dual-homed site cannot use the default site ID. You must manually assign the same site ID to them.
· The edge device at a single-homed site can use the default or manually assigned site ID. Site conflict does not occur if the edge devices at different sites all use the default site ID.
· Manually assigned site IDs must be unique among sites.
When the site IDs of two devices conflict, EVI IS-IS isolates the device with the lower MAC address. The isolated device cannot exchange any EVI IS-IS packets with other neighbors except that it can receive EVI IS-IS hello packets. To identify isolated devices, use the display evi isis brief command or the display evi isis peer command.
Examples
# Assign a site ID of 201 to the device.

Parameters
local-vlan-id: Specifies a local VLAN ID in the range of 1 to 4094.
remote-vlan-id: Specifies a remote VLAN ID in the range of 1 to 4094.
site site-id: Specifies a remote site ID in the range of 1 to 65535. If you do not specify a site, this command maps the local VLAN to the remote VLAN for all remote sites.
Usage guidelines
If two sites use different VLANs to convey the same service, you can configure a mapping between the VLANs at the two sites. You must specify the VLANs as extended VLANs on the corresponding EVI tunnel interfaces.
For example, site 1 uses VLAN 100 and site 2 uses VLAN 200 to transmit data service. At site 1, map VLAN 100 to VLAN 200. At site 2, map VLAN 200 to VLAN 100. When the edge device at site 1 receives MAC addresses from site 2 in VLAN 200, it adds the MAC addresses to VLAN 100 automatically. Likewise, when the edge device at site 2 receives MAC addresses from site 1 in VLAN 100, it adds the MAC addresses to VLAN 200 automatically.
In the mapping at site 1, VLAN 100 is the local VLAN, and VLAN 200 is the remote VLAN.
At a site, a VLAN can have only one mapping for a remote site. The local site considers a remote VLAN invalid if the remote VLAN has the same VLAN ID as the local VLAN in a mapping. The local site drops the MAC addresses received from the remote site in the VLAN. In the previous example, site 1 will drop a MAC address received from site 2 if the address is in VLAN 100.
The undo evi vlan-mapping command removes all VLAN mappings on the EVI tunnel interface if you do not specify a mapping.
Examples
# Map local VLAN 100 to remote VLAN 200 for site 2 on Tunnel 101.
<Sysname> system-view
[Sysname] interface tunnel 101

Predefined user roles
network-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 a task that can trigger automatic EVI IS-IS process creation on a tunnel interface. The ID of an automatically created process is the same as the EVI tunnel interface number. For more information about automatic EVI IS-IS process creation, see EVI Configuration Guide.
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.

network-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 acknowledgment 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 acknowledgment or keepalive packet.
Examples
# Set the keepalive interval to 20 seconds and the maximum number of consecutive keepalive failures to 5.

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.

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 event.
version-skew: Specifies notifications about hello packet version mismatches.
Usage guidelines
To report critical EVI IS-IS events to an NMS, enable SNMP notifications for EVI IS-IS.
If you do not specify a notification, this command enables all EVI IS-IS SNMP notifications.
For EVI IS-IS SNMP notifications to be sent correctly, you must also configure SNMP on the device. For more information about SNMP configuration, see the network management and monitoring configuration guide for the device.
Examples
# Enable EVI IS-IS adjacency status change notifications.

[Sysname] snmp-agent trap enable evi-isis adjacency-state-change
timer lsp-max-age
Use timer lsp-max-age to specify the maximum lifetime of LSPs.
Use undo timer lsp-max-age to restore the default.
Syntax
timer lsp-max-age seconds
undo timer lsp-max-age
Default
The maximum LSP lifetime is 1200 seconds.
Views
EVI IS-IS process view
Predefined user roles
network-admin
Parameters
seconds: Specifies the maximum LSP lifetime in the range of 3 to 65535 seconds.
Usage guidelines
This command specifies the maximum amount of time an LSP generated by the local EVI IS-IS process can be valid in an LSDB. When the timer decreases to zero, the LSP is removed from the LSDB.
Examples
# Set the maximum LSP lifetime to 25 minutes (1500 seconds) on EVI IS-IS process 101.
<Sysname> system-view
[Sysname] evi-isis 101
[Sysname-evi-isis-101] timer lsp-max-age 1500

timer lsp-refresh
Use timer lsp-refresh to specify the LSP refresh interval.
Use undo timer lsp-refresh to restore the default.
Syntax
timer lsp-refresh seconds
undo timer lsp-refresh
Default
The LSP update interval is 900 seconds.
Views
EVI IS-IS process view
Predefined user roles
network-admin
Parameters
seconds: Specifies an LSP refresh interval in the range of 1 to 65534 seconds.
Usage guidelines
Each edge device updates the LSPs that they generated at the LSP refresh interval to maintain LSDB consistency across the EVI network.
To avoid unnecessary LSP age-outs at remote edge devices, make sure the LSP refresh interval is shorter than the LSP lifetime.
Examples
# Set the LSP refresh interval to 1500 seconds.
<Sysname> system-view
[Sysname] evi-isis 101
[Sysname-evi-isis-101] timer lsp-refresh 1500

virtual-system
Use virtual-system to create an EVI IS-IS virtual system.
Use undo virtual-system to delete an EVI IS-IS virtual system.
Syntax
virtual-system systemid
undo virtual-system systemid
Default
No EVI IS-IS virtual systems exist.
Views
EVI IS-IS process view
Predefined user roles
network-admin
Parameters
systemid: Specifies a virtual system ID in the XXXX.XXXX.XXXX format. Each X represents a hexadecimal digit.
Usage guidelines
The virtual system ID must be unique in the EVI network.
An EVI IS-IS process sends all local MAC reachability information in one LSP. By default, an LSP can convey up to 55 x 210 MAC address entries.
To increase this number to accommodate all local MAC address entries, create virtual systems. Each virtual system represents an increase of 55 x 210 MAC address entries.
Examples
# Create the virtual system 0001.0001.0001.
<Sysname> system-view
[Sysname] evi-isis 101
[Sysname-evi-isis-101] virtual-system 0001.0001.0001
