Huawei quidway s7700 User Manual

The GR capability of BGP is enabled.
4. (Optional) Run:
graceful-restart timer restart time
The maximum time for restarting the GR Restarter is configured.
The restart period is the maximum waiting period, from the time when the receiving
speaker detects that the GR Restarter restarts, to the time when the BGP session is
reestablished. If no BGP session is reestablished within the restart period, the receiving
speaker deletes the BGP route in the stale state. By default, the restart period is 150
seconds.
CAUTION
Modifying the restart period leads to the reestablishment of the BGP peer relationship.
5. (Optional) Run:
graceful-restart timer wait-for-rib time
The time of waiting for the End-of-RIB message is configured.
By default, the time of waiting for the End-of-RIB message is 600 seconds.

3.13.5 Configuring BGP GR for MP-BGP
When MP-BGP restarts, the peer relationship is re-established and traffic forwarding is
interrupted. If BGP GR is enabled, traffic interruption can be prevented.
Context
Configure BGP GR for MP-BGP on all the PEs (including the PE that serves as the ASBR) and
the RRs that reflect the VPNv4 route, unless BGP GR has been configured for MP-BGP when
BGP GR is configured between PEs and CEs.
The process of configuring BGP GR for MP-BGP is the same as that of configuring GR in the
common BGP. For the detailed configuration, see 3.13.4 Configuring GR of the Routing
Protocol Between PEs and CEs.
3.13.6 Checking the Configuration
After configuring VPN GR, you can view status information about IGP GR and BGP GR.
Prerequisite
The configurations of the VPN GR function are complete.
Procedure
l Run the display ospf brief command to check the status of the OSPF GR.
l Run the display isis graceful-restart status [ level-1 | level-2 ] [ process-id | vpn-
instance vpn-instance-name ] command to check the status of the IS-IS GR.
