3.13.4 Configuring GR of the Routing Protocol Between PEs and
CEs
You can configure GR of a routing protocol according to the specific routing protocol running
between the CE and the PE. GR of a routing protocol can be IS-IS GR, OSPF GR, or BGP GR.
Context
NOTE
When configuring GR of the routing protocol running between PEs and CEs, configure the corresponding
GR (IS-IS GR, OSPF GR, or BGP GR) according to the routing protocol running between the PEs and
CEs.
Procedure
l Configure GR of the IS-IS multi-instance between PEs and CEs.
Do as follows if IS-IS is run between the PE and the CE:
1. Run:
system-view
The system view is displayed.
2. Run:
isis process-id vpn-instance vpn-instance-name
The IS-IS multi-instance view is displayed.
3. Run:
graceful-restart
The IS-IS GR capability is enabled.
By default, the IS-IS GR capability is disabled.
4. (Optional) Run:
graceful-restart interval interval-value
The interval for reestablishing the IS-IS GR session is configured.
The interval for reestablishing the IS-IS GR session is set to the Hold time in the IS-
IS Hello PDU. In this manner, the neighbor does not terminate the adjacency
relationship with the switch when the switch performs the AMB/SMB switchover.
By default, the interval for reestablishing the IS-IS GR session is 300 seconds.
5. (Optional) Run:
graceful-restart suppress-sa
The GR Restarter is configured to suppress the advertisement of the adjacency
relationship when it is restarting.
