Re: [Isis-wg] Accept as WG doc?

Hannes,

We propose to carry multicast information in a new Multicast-Group PDU to
address:
 ­Rapid join/leave multicast group events to not impact unicast-spf/lsp
flooding 
 ­Management separation of multicast group information
 ­Increase LSP-ID space for large volumes of multicast information
 ­Efficient SPF runs and multicast-attachment updates due to database
separation 
 ­Inter-operability with older implementations is not of any concern

Please note that 
(a) ³Extending LSP space² draft can be used in addition to what is being
proposed. 
(b) ³Multiple instances² draft separates the databases. However, here the
multicast 
information is to be used in conjunction with the uni-cast information.

Thanks,
Ayan

 hi david, et al,
 
 may i ask why there is need for dedicated PDU types ?
 
 i feel a bit of discomfort adding a set of new PDU types
 which only cover existing functionality, just because of
 of extending or seperating LSP space. it is my view that
 we already have vehicles to address that.
 
 two (hard) questions:
 
 1. why is the "multiple instances" draft not good enough
    seperating the different databases ? it seems like
    we are getting down the road of PDU-type being
    a functional database multiplexer.
 
 2. why is the "extending LSP space" draft not good enough
    if LSP space shortage is of concern ?
