I have an OSPF connectivity problem. I have 3 routers as follows: OSPF Area 203.147.188.0 OSPF Area 0 Gw1.bne2 ------------------------ Gw2.bne -------------------Gw1.bne
Gw1.bne2 is connecting to Gw2.bne with Serial 0/0:0 (203.147.255.186 /30) Gw2.bne is connecting back to Gw1.bne2 with Serial 0/0:0 (203.147.255.185 /30) Gw2.bne is also connected to Gw1.bne with FastEth 0/0 (202.139.236.2 /24) Gw1.bne is connecting back to Gw2.bne with FastEth 0/1 (202.139.236.254 /24) Now I have 5 static routes at Gw1.bne2 (the left most Router) that I want to redistributed into OSPF. ip route 203.147.154.0 255.255.255.128 203.147.188.65 ip route 203.147.154.128 255.255.255.248 203.147.188.68 ip route 203.147.154.136 255.255.255.248 203.147.188.69 ip route 203.147.154.144 255.255.255.252 203.147.188.66 ip route 203.147.154.148 255.255.255.252 203.147.188.67 controller E1 0/0 channel-group 0 timeslots 1-31 ! ! interface Tunnel0 description BNE2->Avior ip address 10.255.255.2 255.255.255.252 no ip route-cache cef tunnel source 203.147.255.186 tunnel destination 203.147.190.4 ! interface FastEthernet0/0 no ip address ip route-cache flow speed 100 full-duplex ! interface FastEthernet0/0.5 encapsulation dot1Q 5 ! interface FastEthernet0/0.10 encapsulation dot1Q 10 ip address 10.15.15.254 255.255.255.0 secondary ip address 203.147.188.254 255.255.255.0 ip access-group pfilter in ip accounting access-violations ip nbar protocol-discovery ! interface FastEthernet0/0.999 encapsulation dot1Q 999 ip address 10.2.101.1 255.255.0.0 ! interface Serial0/0:0 description N7065870L to 96 Lytton Rd ip address 203.147.255.186 255.255.255.252 ip nbar protocol-discovery ip route-cache flow load-interval 30 service-policy output voippol ! router ospf 7496 log-adjacency-changes redistribute connected redistribute static subnets passive-interface FastEthernet0/0.999 network 203.147.188.0 0.0.0.255 area 203.147.188.0 network 203.147.255.184 0.0.0.3 area 203.147.188.0 At Gw1.bne2, it shows the subnets are learned via "statics" gw1.bne2#sh ip route 203.147.154.136 Routing entry for 203.147.154.136/29 Known via "static", distance 1, metric 0 Redistributing via ospf 7496 Advertised by ospf 7496 subnets Routing Descriptor Blocks: * 203.147.188.69 Route metric is 0, traffic share count is 1 When I goto Gw2.bne (middle router), I can see the routes in the OSPF Topology Table (all of them are learned from 203.147.255.186 - Gw1.bne2), but not the its routing table:- N.B: I also tried to do a clear ip route 203.147.144.0/20, but no help.
