Step 1: Display routing table of Switch D
SwitchD#show ip route
Codes: C - connected, S - static, R - RIP, B - BGP
O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default
Gateway of last resort is no set
S 172.10.10.0/24 [1/0] via 192.168.6.2 //static route
O IA 192.168.1.0/24 [110/2] via 192.168.3.1, 15:25:19, GigabitEthernet 0/3
O IA 192.168.2.0/24 [110/3] via 192.168.3.1, 15:25:19, GigabitEthernet 0/3
C 192.168.3.0/24 is directly connected, GigabitEthernet 0/3
C 192.168.3.2/32 is local host.
O IA 192.168.5.0/24 [110/4] via 192.168.3.1, 15:11:56, GigabitEthernet 0/3
C 192.168.6.0/24 is directly connected, GigabitEthernet 0/4
C 192.168.6.1/32 is local host.
Step 2: View OSPF information of Switch D. Key point: Switch D is a AS boundary
router (ASBR).
SwitchD#show ip ospf
Routing Process "ospf 1" with ID 192.168.3.2
Process uptime is 15 hours 27 minutes
Process bound to VRF default
Conforms to RFC2328, and RFC1583Compatibility flag is enabled
Supports only single TOS(TOS0) routes
Supports opaque LSA
Enable two-way-maintain
This router is an ASBR (injecting external routing information)
