Greetings all, i used one of the online vrack rental website that is using the 2600 series with IOS c2600-advipservicesk9-mz.123-18.bin and other 2600 routers with IOS c2600-adventerprisek9-mz.124-5.bin. the issue with the first IOS is that it is accepting all the OSPF CLI but there is no OSPF neighborship with other 2600 that are running the second IOS. what could be the issue? 2 spoke routers in FR cloud one is running the first code and other is running the second code with identical config with the hub. no connection with the first but connection is fine with the second.
regards
