Disabling OSPF IP FRR on an OSPF Multi-Area Adjacency Interface

OSPF IP fast reroute (FRR) can be disabled on an OSPF multi-area adjacency interface that is connected to a link carrying key services. This prevents FRR from calculating the link as the backup link and minimizes any potential impact on the services.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The interface view is displayed.
Run ospf enable [ process-id ] area area-id
OSPF is enabled on the interface.
Run ospf enable multi-area area-id
OSPF is enabled on the multi-area adjacency interface.
Run ospf frr block multi-area area-id
OSPF IP FRR is disabled on the OSPF multi-area adjacency interface.
(Optional) Run ospf remote-lfa disable multi-area area-id
Remote loop-free alternate (LFA) is disabled on the OSPF multi-area adjacency interface.
Run commit
The configuration is committed.
