Hello,
I am having a routing problem and am hoping someone can point me in the
right direction. Thanks in advance.
Lab Setup:
- I have a pair of 2501's (R1 and R2) hooked up via the serial ports.
(10.0.1.1 and 10.0.1.2)
- The eth0 port of R1 is connected to a switch with 5 PCs and a Cisco 675
DSL router (R1=10.0.0.100, PC1=10.0.0.13, 675=10.0.0.1)
- The eth0 port of R2 connected to a hub and one PC. (R2=10.0.2.1 and
PC2=10.0.2.2)
Routing:
I have setup static routes on R1, R2 and the 675 for all networks (see
routing tables below)
The 675 is the default gateway for the 10.0.0.0 network
Problem:
- From PC1 and R1 I can ping everything on the network (no problems)
- From the PC2 and R2 I can ping everything except the 675 (10.0.0.1).
- From 675 I can only ping 10.0.0.0 network. Cannot even ping serial
interface on R1.(eth0=10.0.0.100, serial1=10.0.1.1)
Questions:
- The problem seems to lie in the way the 675 answers ping responses and is
there a setting that needs to be turned on to answer remote requests?
- Could the problem be in the routes or default gateways?
Thanks again
-Alan
