6509 IOS Routing Path

vtra
Level 1
Level 1


Using 6509 attached to muliple firewalls leading to different destinations.  I'm in a new environment and have no knowledge of their layout.

Is there a way to find out what path the packets are taking?

In the past, I would do a "Sh ip int brief"

List of vlan is displayed with ip address.

I usually do a "traceroute" from one of these sources to find the path that it is taking to a destination.  However, in this cases icmp is blocked by firewall.

The default gateway on these server point to the router and not firewall. I have no access to the server.

Example.

Given server "aaa" ip info, and it's targeted destination, how can i tell if its passing through firewall a or firewall b?  Besides the method above, I'm thinking of doing "sh ip route xx.xx.xx.xx" the "Last update from 10.129.12.9 on Vlan312, 2d07h ago" is the default gateway right?

CORE1#sh ip route 0.0.0.0


Routing entry for 0.0.0.0/0, supernet
  Known via "ospf 129", distance 110, metric 2, candidate default path
  Tag 141049920, type extern 1
  Last update from 10.129.12.9 on Vlan312, 2d07h ago
  Routing Descriptor Blocks:
  * 10.129.12.9, from 12.149.44.148, 2d07h ago, via Vlan312
      Route metric is 2, traffic share count is 1
      Route tag 141049920

Thank you for the Assistance
