Configuring OSPF FRR
Network requirements
Router S, Router A, and Router D belong to the same OSPF domain as shown in
Configure OSPF FRR so that when the link between Router S and Router D fails, traffic is
immediately switched to Link B.

Configuration procedure
Configure IP addresses for the interfaces on each router and configure OSPF:
1.
Follow
(Details not shown.)
Configure OSPF on the routers, ensuring that Router S, Router A, and Router D can
communicate with each other at Layer 3. (Details not shown.)
Configure OSPF FRR:
2.
You can enable OSPF FRR to either automatically calculate a backup next hop, or designate a
backup next hop by using a routing policy.
Method 1: Enable OSPF FRR to automatically calculate a backup next hop.
# Configure Router S.
<RouterS> system-view
[RouterS] bfd echo-source-ip 1.1.1.1
[RouterS] ospf 1
[RouterS-ospf-1] fast-reroute auto
[RouterS-ospf-1] quit
# Configure Router D.
<RouterD> system-view
[RouterD] bfd echo-source-ip 4.4.4.4
[RouterD] ospf 1
[RouterD-ospf-1] fast-reroute auto
[RouterD-ospf-1] quit
Method 2: Enable OSPF FRR to designate a backup next hop by using a routing policy.
