[j-nsp] Juniper MX240 to Alcatel SAS-M epipe

[Eduardo Barrios]

It's a mixture of Alcatel and Juniper, we always use the lowest MTU 2102 (this is the MAX MTU on a 7705). Our M10s do 9192.  Even though we might have a primary path that was discovered @ 9192 we still have to take into account detours and secondary paths that might be 2102.

Not sure what ALU do, but if it's anything like IOS, it'll
be a 14-byte difference from Junos.

If you own the backhaul (or have some measure of control
over it), just run 9,000 bytes or more and be done with it.
