Hi there, guys when I configured the relationship between R2 AND R7 by using the network 150.100.36.0/24 as primary network for both routers interface the relationship has established, but when I configured the R2 f0/0 as 150.100.68.0/24 as primary network according to the book, the relationship between R2 AND R7 went down. but when I configured both interfaces at R2 AND R7 under same primary network 150.100.36.0/24 both routers worked fine. So, what I should do I have to leave both f0/0 interface under the same network 150.100.36.0/24 in order to ensure my relationship? Please, check my configuration is there any thing not normal?
R2 interface FastEthernet0/1 ip address 150.100.68.2 255.255.255.0 secondary ip address 150.100.36.2 255.255.255.0 duplex auto speed auto R2(config-if)#do sr | s os hostname R2 router ospf 1 router-id 10.10.2.2 log-adjacency-changes passive-interface default no passive-interface FastEthernet0/1 network 10.10.2.2 0.0.0.0 area 72 network 150.100.36.0 0.0.0.255 area 72 R2(config-if)#do sh ip os nei Neighbor ID Pri State Dead Time Address Interface 10.10.7.7 1 FULL/DR 00:00:38 150.100.36.7 FastEthernet0/1 -------> relationship has established between R2 AND R7 R7 interface FastEthernet0/1 ip address 150.100.68.7 255.255.255.0 secondary ip address 150.100.36.7 255.255.255.0 duplex auto speed auto R7#sr | s os hostname R7 router ospf 1 router-id 10.10.7.7 log-adjacency-changes passive-interface default no passive-interface FastEthernet0/1 network 10.10.7.7 0.0.0.0 area 72 network 150.100.36.0 0.0.0.255 area 72 R7#sh ip os n Neighbor ID Pri State Dead Time Address Interface 10.10.2.2 1 FULL/BDR 00:00:39 150.100.36.2 FastEthernet0/1 R7# note: According to the WB we have to configure R2 f0/0 interface as primary network of 150.100.68.0/24 and to keep the R7 f0/0 interface as 150.100.36.0/24 primary network, however adj relationship will not established in this case unless we have both interface f0/0 at vlan 721 for both routers R2 AND R7 are sharing the same primary interface network? best regards, khaled _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
