Configuring OSPF for a Virtual Link on Switch #2
1.
Configure IP interfaces on each network that will be attached to OSPF areas.
Two IP interfaces are needed on Switch #2: one for the transit area network on 10.10.12.0/24
and one for the stub area network on 10.10.24.0/24.
2.
Configure the router ID.
A router ID is required when configuring virtual links. This router ID should be the same one
specified as the target virtual neighbor (
nbr
) on Web switch 1 in
.
3.
Enable OSPF.
