Hi all,
I
have one question about MAC Address Withdraw Message in RFC4762 RFC4762
say We
introduce an optional MAC List TLV in LDP to specify
a list of MAC addresses that can be
removed or unlearned using the LDP Address Withdraw
Message.
And
also say The
MAC Address Withdraw Message contains a FEC TLV (to identify the VPLS affected),
a MAC Address TLV, and optional parameters. No optional parameters have been defined
for the MAC Address Withdraw signaling. This
two segment is contradiction. The
first segment say that the MAC
Address TLV is optional parameters. But the second segment impliedly say that
the FEC TLV and the MAC Address TLV must be included . Since
the MAC Address Withdraw Message and Address
Withdraw Message
used the same message type (0x0301). So my question is how to process the message which message type is 0x0301 and which TLV is mandatory when we parse this message . Further
question is, If
Address list TLV is mandatory .Then how to fill the Address list TLV for L2VPN,
since the ip address is not usefule for L2VPN. If Address list TLV is not mandatory .Then how to fill MAC Address Withdraw Message and Address Withdraw Message when this remote peer session is used not only for L2VPN but also for other application (for example TE).
Thanks and Regards Vivienne
