[rbridge] ????: ????: rbridge for ipv6 ?

[Vishwas Manral]

Hi Yiou,

I am not sure if IS-IS is the preferred protocol (I guess we are some distance from finalizing a protocol), however one advantage of IS-IS is that it uses TLV based reachability information and hence is independent of the protocol for which it carries information (It was initially used for the OSI stack and later extended to work for TCP/IP).

Besides IS-IS already works over Layer-2.

Thanks,
Vishwas

　　Hi Ganesh,
　　I mean that ANY of the routing protocols can be used for rbridge
reachability. I'm new for this mailing list and know little about why
ISIS is preferred for rbridge. Will anyone be kind enough to explain
this for me? Thanks in advance.

　　Hi Yiou,
　　Do you mean that still routing protocols other than IS-IS routing
are
　　required just for rbrige reachability ?
