Configuring BGP GR

Perform the following configuration on the GR Restarter and GR Helper respectively.
A device can act as a GR Restarter and GR Helper at the same time.
Follow these steps to configure BGP GR:
To do...
Enter system view
Enable BGP, and enter its view
Enable GR Capability for BGP
Configure the maximum time
allowed for the peer to
reestablish a BGP session
Configure the maximum time to
wait for the End-of-RIB marker
In general, the maximum time allowed for the peer (the GR restarter) to reestablish a BGP session
should be less than the Holdtime carried in the OPEN message.
The End-Of-RIB (End of Routing-Information-Base) indicates the end of route updates.
Enabling Trap
After Trap is enabled for BGP, BGP generates Level-4 traps to report important events of it. The
generated traps are sent to the Information Center of the device. The output rules of the traps, namely,
whether to output the traps and the output direction, are determined according to the Information Center
configuration. (For Information Center configuration, refer to "Information Center Configuration" in the
System Volume.)
