Hi

If it is a trunk port, then it should accomdate 1 label and as an
access-port, 2 labels. But would suggest using the entire jumbo
size(1546/9000).

Hello all





 We have an MPLS enable network and I have a question regarding trunk-switch
interfaces. We set MTU size on all switch interfaces to 1526 in order to
accommodate MPLS packets. Do we need to increase MTU above 1526 on switch
trunk interfaces?





Thank you
