1.What are the steps and commands I must use to check if router A can't connect to Router B but it has no problem connecting to other routers and it was suspected that an entry has been deleted in router A?

2. Will the following static routes, RIP and IGRP route individually through their own paths or are they bounded together on the same interface


Thanks mikecr, I appreciate your help very much

1. First thing that you check is connectivity by using the PING and TRACEROUTE commands of TCP/IP if that's the protocol being used. You should also use SHOW INTERFACE, and SHOW CONFIG to help evaluate the problem. It will depend on the type of problem that your experiecing. Lack of connection could be layer 3 routing, layer 2 protocols, and layer 1 hardware. If you don't believe it's harware then you you need to check configurations on the router in question. You may need to get deeper and use Debug commands on the router to help. If the configuration seems correct then you would need to start looking at hardware issues like cabling or bad cards.

2. Static routing, IGRP, and RIP routing is done by network, so with this in mind they can be used on the same network or separate networks to do routing. You can also redistribute routes amoung routing protocols for learned networks. Say I use IGRP on by serial interface network to route and RIP on the ethernet network to route. I can use commands typical to that routing protocol to redistribute the routes that IGRP learns to the RIP protocol and vice versa.

You would use:

traceroute 10.1.1.1.
ping 10.1.1.1
show ip route
show ip route igrp
show ip router eigrp
show ip route bgp
show ip route static

These commands will show you the route tables on the router depending on the protocol used and using the ping and traceroute commands will show where the connection problems lies.
