Re: OSPF over FR [7:70025]
Catherine, You forget to define ospf network type in each frame interface. Add this interface config command: ip ospf network point-to-point Thank, Rivalino Exactly right but you will have to do 2 more things: 1)Since you changed the hello-interval to 30 on Router A's point-to-point subinterfaces you will have to do the same for Router B and Router C's interfaces. 2) Remove the neighbor statement from Router B and Router C's OSPF process. Not needed. So just add the "ip ospf network point-to-point on Routers B and C frame relay physical interface and do steps 1 and 2. Best of luck.

RE: OSPF over FR [7:70025]
Hi Catherine, Because you are using point to point sub interfaces on the one routea and one the other just using the real interface, OSPF behaves differently and has different helo / dead timers etc, and this is why you are not getting all your routes. You need to make sure that all ospf interfaces in the same area are of the same "network type" using the interface command ip ospf network Below is a link to a quick ref http://www.chuckslongroad.info/OSPF_Frame_Reference.htm Catherine Wu wrote: > > I am testing Hub-Spoke for OSPF over FR, > > I verified the neighbor adjacency,but I couldn't see route > 2.2.2.2 and > 3.3.3.3 in the routing table, > > RouterA#sh ip ospf nei > > Neighbor ID Pri State Dead Time > Address Interface > 3.3.3.3 1 FULL/ -00:01:4110.1.1.6 > Serial0/0.2 > 2.2.2.2 1 FULL/ -00:01:3910.1.1.2 > Serial0/0.1 > RouterB#sh ip ospf nei > > Neighbor ID Pri State Dead Time > Address Interface > 1.1.1.1 1 FULL/BDR00:01:38 > 10.1.1.1Serial0/0 > RouterC#sh ip ospf nei > > Neighbor ID Pri State Dead Time > Address Interface > 1.1.1.1 1 FULL/BDR00:01:34 > 10.1.1.5Serial0/0 > > RouterA#sh ip ro > Codes: C - connected, S - static, I - IGRP, 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, E > - EGP >i - IS-IS, 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 not set > > 1.0.0.0/32 is subnetted, 1 subnets > C 1.1.1.1 is directly connected, Loopback0 > 10.0.0.0/30 is subnetted, 2 subnets > C 10.1.1.0 is directly connected, Serial0/0.1 > C 10.1.1.4 is directly connected, Serial0/0.2 > > Please help. > > Thanks > > Catherine > > RouterA > interface Loopback0 > ip address 1.1.1.1 255.255.255.255 > ! > interface Serial0/0 > no ip address > encapsulation frame-relay > frame-relay lmi-type ansi > no sh > ! > interface Serial0/0.1 point-to-point > ip address 10.1.1.1 255.255.255.252 > ip ospf hello-interval 30 > frame-relay interface-dlci 101 > ! > interface Serial0/0.2 point-to-point > ip address 10.1.1.5 255.255.255.252 > ip ospf hello-interval 30 > frame-relay interface-dlci 102 > ! > router ospf 1 > log-adjacency-changes > network 1.1.1.1 0.0.0.0 area 1 > network 10.1.1.0 0.0.0.3 area 0 > network 10.1.1.4 0.0.0.3 area 0 > > RouterB > ! > interface Loopback0 > ip address 2.2.2.2 255.255.255.255 > ! > interface Serial0/0 > ip address 10.1.1.2 255.255.255.252 > encapsulation frame-relay > frame-relay map ip 10.1.1.1 110 broadcast > no frame-relay inverse-arp > frame-relay lmi-type ansi > no sh > ! > router ospf 1 > log-adjacency-changes > network 2.2.2.2 0.0.0.0 area 2 > network 10.1.1.0 0.0.0.3 area 0 > neighbor 10.1.1.1 > ! > RouterC > interface Loopback0 > ip address 3.3.3.3 255.255.255.255 > ! > interface Serial0/0 > ip address 10.1.1.6 255.255.255.252 > encapsulation frame-relay > frame-relay map ip 10.1.1.5 120 broadcast > no frame-relay inverse-arp > frame-relay lmi-type ansi > no sh > ! > router ospf 1 > log-adjacency-changes > network 3.3.3.3 0.0.0.0 area 3 > network 10.1.1.4 0.0.0.3 area 0 > neighbor 10.1.1.5 > > [GroupStudy removed an attachment of type application/ms-tnef > which had a name of winmail.dat] > > Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=70054&t=70025 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
