Hello,

First I appologize about the long post but this problem is getting me. I am trying to up my skills regarding Cisco routers and am having some issues so any help would be very very appreciated.

The scenario: I have 3 Cisco 3640s all connected with the interfaces IP’d and talking but I cannot get the outside interfaces to respond to pings. Here is the equipment and topology.



3640A - 3 interfaces used

Ethernet3/0 192.168.1.1/24
Ethernet3/1 10.0.2.1/24
Serial3/1 10.0.1.1/24



3640B - 2 interfaces used

Ethernet3/0 10.0.2.2/24
Ethernet3/1 192.168.3.1/24



3640C - 2 interfaces used

Ethernet0/0 192.168.2.1/24
Serial0/1 10.0.1.2/24


Topology


e0/0 3640C s0/1 --- s3/1 3640A e3/1 --- e3/0 3640B e3/1


I can get any router to ping any interface that connects a router. I cannot get router B to ping the 192 address on router C and vice versa. Beating my head against a wall.....

Thank-you.
 
your router A has wrong statement:

ip route 192.168.2.0 255.255.255.0 10.0.2.2

should be

ip route 192.168.2.0 255.255.255.0 10.0.1.1

the other two will only need one statement:

router B
ip route 0.0.0.0 0.0.0.0 10.0.2.1

router C
ip route 0.0.0.0 0.0.0.0 10.0.1.1
