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 -----Original Message----- From: Garry Glendown [mailto:garry@regio.net] Sent: mercredi 15 septembre 2004 09:30 To: mpls-ops@mplsrc.com 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?
