O E2 172.10.10.0/24 [110/20] via 192.168.1.2, 00:07:37, GigabitEthernet 0/1
O IA 192.168.3.0/24 [110/2] via 192.168.1.2, 15:33:00, GigabitEthernet 0/1
O 192.168.5.0/24 [110/2] via 192.168.2.2, 15:14:59, GigabitEthernet 0/2
O IA 192.168.6.0/24 [110/3] via 192.168.1.2, 00:17:58, GigabitEthernet 0/1
From the above information, we can see that Switch A has successfully learned
the route to the network segment of 172.10.10.0.
4.4.6 OSPF Dynamic Route Redistribution Configuration Example
Requirements
There are four devices which are connected as per following figure. Router A
belongs to OSPF routing domain; router C belongs to RIP routing domain; router
D belongs to BGP routing domain; router B is connected with three routing
domains. Router A advertises the following two routes: 192.168.10.0/24 and
192.168.100.1/32; router C advertises the following two routes of 192.168.3.0/24
and 192.168.30.0/24; router D advertises the following two routes: 192.168.4.0/24
and 192.168.40.0/24.
