3.13.2 Configuring IGP GR on the Backbone Network
You can configure IGP GR based on the specific IGP running on the backbone network. IGP
GR can be IS-IS GR or OSPF GR.
Context
NOTE
When configuring GR on the backbone network, configure the corresponding IGP GR (IS-IS GR or OSPF
GR) based on the specific IGP protocol running on the backbone network.
Procedure
l
Configure IS-IS GR on the backbone network.
If IS-IS is running on the public network, do as follows on the related PEs and Ps on the
backbone network:
1.
Run:
system-view
The system view is displayed.
2.
Run:
isis
process-id
The IS-IS 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.
