Hi All
I am triing to configure link between MX240 and SAS-M. I want to terminate
Alcatel epipe on MX. I used l2circuit to do this. I can ping address in the
Internet but not every webpage work. I think the problem is in MTU in
epipe. Alcatel has MTU 1522. How to calculate MTU size for MX? Thanks for
help in advance.

Current configuration:
 show protocols l2circuit
traceoptions {
    file debug-l2circuit size 1m files 5;
neighbor {
    interface ge-2/1/9.0 {
        virtual-circuit-id 11;
    interface ge-2/1/1.0 {
        virtual-circuit-id 12;
        mtu 1522;
