Configuring the maximum lifetime for routes in the
FIB
When GR or NSR is disabled, FIB entries must be retained for some time after a protocol process
switchover or RIB process switchover. When GR or NSR is enabled, FIB entries must be removed
immediately after a protocol or RIB process switchover to avoid routing issues. Perform this task to meet
such requirements.
To configure the maximum lifetime for routes in the FIB (IPv4):
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter RIB view. rib N/A
3. Create a RIB IPv4 address
family and enter its view.

By default, no RIB IPv4
address family is created.
4. Configure the maximum
lifetime for IPv4 routes in the
FIB.
