Configuring OSPF FRR
Network requirements
Router S, Router A, and Router D belong to the same OSPF domain as illustrated in Figure 47 . Configure
OSPF FRR so that when the link between Router S and Router D fails, traffic can be switched to Link B
immediately.
Figure 47 Network diagram
Configuration procedure
1. Configure IP addresses for the interfaces on each router and configure OSPF:
Follow
Figure 47 to configure the IP address and subnet mask of each interface on the routers.
(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)
2. Configure OSPF FRR:
