Usage guidelines
BGP uses this timer to control the time to receive updates from the peer. The timer is not advertised
to the peer.
After the GR restarter and GR helper re-establish a BGP session, they start this timer. If they do not
complete route exchange within the time period, the GR restarter does not receive new routes. It
updates its routing table and forwarding table with learned BGP routes, and the GR helper removes
the stale routes. Set a large value for the maximum time to wait for the End-of-RIB marker when a
large number of routes exist.
This command controls the routing convergence speed. A smaller timer value means faster routing
convergence but possibly results in incomplete routing information.
Before configuring this command, you must enable the BGP GR capability.
Examples
# Set the time to wait for the End-of-RIB marker on the local end to 100 seconds.
