[j-nsp] Juniper Ethernet MTU question

[Ihsan Junaidi Ibrahim]

Hi all,

2 questions:

1) On a 12-port FE PIC, for vlan-cc encapsulation, should the interface MTU
be configured as 1518, 1522 or 1504? The documentation below indicates that
for vlan-ccc encapsulation, it's a 4-byte field but I need to be certain.

2) For a 12-port FE PIC, if I were to configure the maximum physical MTU of
1532, will the PIC be able to accommodate MPLS MTU?
