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 | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter RIB view. | rib | N/A |
3. Create the RIB IPv4 address family and enter its view. | address-family ipv4 | By default, no RIB IPv4 address family exists. |
4. Set the maximum lifetime for IPv4 routes in the FIB. | fib lifetime seconds | By default, the maximum lifetime for routes in the FIB is 600 seconds. |
To set the maximum lifetime for routes in the FIB (IPv6):
Step | Command | Remarks |
---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter RIB view. | rib | N/A |
3. Create the RIB IPv6 address family and enter its view. | address-family ipv6 | By default, no RIB IPv6 address family exists. |
4. Set the maximum lifetime for IPv6 routes in the FIB. | fib lifetime seconds | By default, the maximum lifetime for routes in the FIB is 600 seconds. |
