3. Enter EVI IS-IS process
view.

4. Configure an SNMP
context name for the EVI
IS-IS process.
snmp context-name
context-name
By default, no SNMP context
name is configured for an EVI
IS-IS process.
Configuring Graceful Restart for an EVI IS-IS process
Enable Graceful Restart for the peer EVI IS-IS processes at two ends of an EVI tunnel to guarantee
nonstop forwarding while the peer EVI IS-IS processes are re-establishing their adjacency after a
process restart or active/standby switchover occurs.
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.
If the edge device is a DED, its hello interval is one-third of the hello interval set by using the evi isis
timer hello command.
To configure Graceful Restart for an EVI IS-IS process:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter EVI IS-IS
process view.
evi-isis
process-id
N/A
3. Enable Graceful
Restart.
graceful-restart
By default, EVI IS-IS Graceful Restart is
disabled.
4. Configure the restart
interval.
graceful-restart interval
interval
The default restart interval is 300 seconds.
If the restarting EVI process fails to complete
re-establishing the adjacency with the peer EVI
process, the EVI link goes down.
Increasing the maximum number of MAC entries in an LSP
for an EVI IS-IS process
An EVI IS-IS process advertises all local MAC reachability information in one LSP. By default, an
LSP can convey up to 55 x 2
10
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 2
10
MAC address entries. If n virtual systems are
created, the maximum number of MAC address entries in an LSP is (n+1) x 55 x 2
10
.
