I have this problem and need your help ASAP.Please see the attached files.
1. on routerA, its s1/0:0 (10.3.15.222/24) is connected to routerB s1/0:2 (10.3.15.221/24)
2. the routerB fa0/1( 10.3.12.51/24) is connected to routerC gig1/0/17 (10.3.12.7)
3. I have a route on the routerB created (ip route 10.1.10.0 255.255.255.0 10.3.12.7) and a host (10.1.10.101/24) is reachable from routerB. However, routerA when I create a route : ip route 10.1.10.0 255.255.255.0 10.3.15.221, I am not able to reach the 10.1.10.0 network
When I ping from the routerA to either 10.3.12.7 or 10.1.10.101, I get time-out
To make room for file attachements, routerB and routerC configs are on the file called routerB
Can anyone please have a look at my configs and diagram and advice ?
RouterC doesn't seem to have a route back to 10.3.15.222, which is used by routerA as a source address when you ping toward routerC, hence routerC not being to reply to ICMP request messages.
Hope this helps,
