OSPF virtual-link

what happens to the routes in the routing table at the distant router from area 0?

seams like router 3 becomes an ABR to area 0.

without the virtual-link the routes are "O IA" from

RTR-3-1700#sh ip ro

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, 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, U - per-user static route

o - ODR, P - periodic downloaded static route

Gateway of last resort is 172.16.23.2 to network 0.0.0.0

172.16.0.0/16 is variably subnetted, 5 subnets, 5 masks

C 172.16.23.0/29 is directly connected, Serial1

O IA 172.16.12.0/30 [110/1600] via 172.16.23.2, 17:08:11, Serial1

O  IA172.16.1.1/32 [110/1601] via 172.16.23.2, 17:08:11, Serial1

O IA 172.16.2.0/25 [110/801] via 172.16.23.2, 17:08:11, Serial1

C 172.16.3.0/24 is directly connected, Loopback0

O IA 192.168.1.0/24 [110/1610] via 172.16.23.2, 17:08:11, Serial1

S* 0.0.0.0/0 [1/0] via 172.16.23.2
