The changes from rev -02 to -03 mainly incorporates comments received during
WG LC:
1- Clarifies that PW Typed WC FEC can be used in any LDP message that allows
FEC element - i.e. Label messages, Address Withdraw [ for VPLS], and
Notification.
2 - New Section 4.4: Applicability of PW Typed WC FEC in VPLS MAC
Withdrawal to allow a PE node to ³wildcard² withdraw **all** MAC addresses
for:
o all VPLS instances; or
o all VPLS instances corresponding to a given PW type.
[ Ack Daniel Cohn for his input ]
3- Mandates that VPLS MAC Wdw (Address Withdrawal) MUST contain an ³empty²
list if PW Typed WC specified in FEC TLV.
