You've got at least two errors in your config. You have 220.127.116.11/30 assigned to a serial link and 18.104.22.168/26 assigned to the ethernet on router A. That is not going to work. Plus you have not told OSPF on router B to advertise static routes (look up the redistribute static command).
There may be more, but I stopped looking. Good luck and good hunting!
In addition to what the two previous responders said, include the keyword "broadcast" at the end of the frame relay map statements so that broadcast and multicast packets (necessary for any routing protocol) will be sent accross the frame relay link.
The reason you can reach the serial port on Router A and not the Ethernet is that when a packet arrives at Router B it will see the serial 0 of Router A as being being directly connected and so pass the packet, however as it has no knowledge on how to get to the Ethernet of router A it will drop the packet.
As indicated by the previous writers you may want to redistribute static routes into OSPF on router B and also renumber your serial link (B to C) ,this should resolve your problem.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
