Setting The Maximum Lifetime For Routes And Labels In The Rib; Setting The Maximum Lifetime For Routes In The Fib - HP FlexFabric 12900E Series Configuration Manual

The RIB records extended attributes of each routing protocol and redistribution relationships of
different routing protocol extended attributes.
Setting the maximum lifetime for routes and labels
in the RIB
Perform this task to prevent routes of a certain protocol from being aged out due to slow protocol
convergence resulting from a large number of route entries or long GR period.
The configuration takes effect at the next protocol or RIB process switchover.
To set the maximum lifetime for routes and labels in the RIB (IPv4):
Step
1. Enter system view.
2. Enter RIB view.
3. Create the RIB IPv4 address
family and enter its view.
4. Set the maximum lifetime for
IPv4 routes and labels in the
RIB.
To set the maximum route lifetime for routes and labels in the RIB (IPv6):
Step
1. Enter system view.
2. Enter RIB view.
3. Create the RIB IPv6 address
family and enter its view.
4. Set the maximum lifetime for
IPv6 routes and labels in the
RIB.

Setting 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 set the maximum lifetime for routes in the FIB (IPv4):
Step
1. Enter system view.
2. Enter RIB view.
3. Create the RIB IPv4 address
family and enter its view.
