  • A 9100 bytes
  • B 9104 bytes
  • C 9108 bytes
  • D 9118 bytes
Explanation

An I-VPLS attached to a B-VPLS must have a service MTU at least 18 bytes smaller than the B-VPLS service MTU to accommodate the PBB header. With a B-VPLS service MTU of 9118 bytes, the maximum I-VPLS service MTU is 9100 bytes.
