Let’s finish our full OSPF topology by adding a new area between R10 and R11.
Configure OSPF area 100 between R10 and R11.
We will configure OSPF using the interface level command and then setup a virtual link between R10 and R3.
ip ospf 10 area 100 ip ospf network point-to-point R10(config)#router ospf 10 R10(config-router)#area 3 virtual-link 184.108.40.206 R3(config)#router ospf 10 R3(config-router)#area 3 virtual-link 100.100.100.100
Let’s verify that the adjacency is ok.
R10#sh ip ospf neigh Neighbor ID Pri State Dead Time Address Interface 220.127.116.11 0 FULL/ - - 10.10.39.1 OSPF_VL0 R3#sh ip ospf neigh Neighbor ID Pri State Dead Time Address Interface 100.100.100.100 0 FULL/ - - 10.10.3.10 OSPF_VL0 R3#sh ip ospf int OSPF_VL0 is up, line protocol is up Internet Address 10.10.39.1/30, Area 0, Attached via Not Attached Process ID 10, Router ID 18.104.22.168, Network Type VIRTUAL_LINK, Cost: 20 Topology-MTID Cost Disabled Shutdown Topology Name 0 20 no no Base SNIP Neighbor Count is 1, Adjacent neighbor count is 1 Adjacent with neighbor 100.100.100.100 (Hello suppressed) Suppress hello for 1 neighbor(s)
We now have a full OSPF topology.
In the next posts, we will explore all the OSPF functionalities.
