Hello, Im having problems passing MPLS Frames bigger than 1504 bytes (MPLS VPN frames) on a Catalyst 2924. Actually i have set the mtu command on all interfaces in 2018 bytes,but when i want to pass frames with 1508 it doesnt work and the switch shows giants error on the interface. I have tried with 2 IOS: -mz.120-5.WC5a -mz-120.5-XU Any idea or workaround? Thanks Ezequiel
