Title: RE: [MPLS-OPS]: IP Routing problem after enabling MPLS?

Dear PA

Is this QOS on Switch, MPLS sensitive & if yes, how? Yr i/p would definitely help to under this aspect as well.

Hi Garry,

My first idea:
See in your cat3550 attached GigE if you get  "ignored" or "Pause output" increments. If so, it could be related to QoS on your catalyst. Try to disable qos on it via global "no mls qos". Check if it does correct your problem.

Otherwise, pursue your troubleshooting in other directions ;-)

PA

Subject: [MPLS-OPS]: IP Routing problem after enabling MPLS?

An interesting thing just happened ... :(

I enabled MPLS on several routers, without setting anything specific ...
(i.e., just added "mpls ip" on some necessary interfaces on the way
between a dialup router and a PE->CE router). Everything seemed to work
out fine, and labels being distributed correctly. Anyway, one of our
uplinks started giving me trouble, with connections/routings as such
working, but severely degraded performance (telnet to ebay.com e.g.
would connect, a GET / would take a minute or more with only occasional
blocks of data transfered) - after disabling MPLS on that router (which
wasn't really necessary anyway), everything worked fine again ... when I
re-enable MPLS on its GigE, the delays are there again ... increasing
the MTU to 1512 doesn't help, either ... (switch backplane is 35/29
series switches, routers involved in the local ethernet are a 12k and 72
series w/ GigE PAs)

Any idea?

Tnx, -gg
