I'm using a 3550-12t with routed ports. Two of the ports are
configured with the default route like this:
ip route 0.0.0.0 0.0.0.0 Gig 0/1 <ip of remote router1>
ip route 0.0.0.0 0.0.0.0 Gig 0/2 <ip of remote router2>
'show ip route 0.0.0.0' indicates:
Routing entry for 0.0.0.0/0, supernet
Known via "static", distance 1, metric 0, candidate default path
Routing Descriptor Blocks:
* <ip of remote router1>, via GigabitEthernet0/1
Route metric is 0, traffic share count is 1
<ip of remote router2>, via GigabitEthernet0/2
Route metric is 0, traffic share count is 1
My first sign of trouble is that the '*' fails to switch back-n-forth
between the two available routes.
All traffic is directed to the interface with the '*' and it never
changes. The second interface has zero outgoing traffic.
Both links show incoming traffic from the remote routers.
This was working before until I moved my equipment to another cabinet
with new links (and new IP addresses and possibly different routers at
the remote end).
So ... what are my symptoms:
a) no outgoing traffic on one interface
b) users complain of sporadic connectivity issues, slow network access
I have posted the output from some troubleshooting commands here:

Thank you for your help!
