Hi, Probably I should have asked some more questions - Hello packet has the following important fields that should match on both routers trying to form adjacency - 1. Network Mask, 2. Hello Interval, 3. Options field 4. Router dead interval Make sure that the neighboring interfaces are of same network type. Are you using any authentications which may not be matching. There is a possibility of accesslist also. What does the debug ip ospf adj say ? Murali CiscoNewbie wrote: Hi and thanks for your reply. I had already attempted what you suggested and still the adjacency does not come up. Can you (or any list member) clarify for me whether the network command along with the wildcard mask have to match exactly as the interface for which you are enabling OSPF is configured for? Would the use of the network statement as follows work as well: network xxx.xxx.xxx.14 0.0.0.3 area 1 or does it have to be netowrk "aligned"? When the hello packets are exchanged, the mask is also carried, so where does the router get the mask for the interface it is advertising? Is it derived from the network statement? Can someone explain what the error that I was seeing means? Thanks. Murali Das wrote:

OSPF: Rcv pkt from xxx.xxx.xxx.13, Serial0/0.1, area 0.0.0.1: src not on the same network I am presuming that the issue here is the subnet mask that I have specified the network statement as under OSPF. My serial interface (frame-relay subinterface) has a /30 mask. How should my network statement be configured if the IP address of the interface is xxx.xxx.xxx.14? I have tried the following: network xxx.xxx.xxx.0 0.0.0.255 area 1 as well as: network xxx.xxx.xxx.12 0.0.0.3 area 1 try this network xx.xx.xx.14 0.0.0.0 area 1 Neither one seemed to work. I still got the same error. The other side is also on the same subnet and it has an IP address of xxx.xxx.xxx.13/30 configured as a P2P as well. If the network statement is not the issue, please advise. Thanks. --------------------------------- Do you Yahoo!? Yahoo! Platinum - Watch CBS' NCAA March Madness, live on your desktop!
