Re: [rbridge] Question on draft-ietf-trill-rbridge-mib-07

Mahesh,

As the INDEX is rbridgeBasePort, there is a unique entry per port and we are only maintaining per port the knowledge that there is at least one multicast router, either v4 or v6, and which one it is (useful from a management perspective). So it should not return a list of all IP multicast router addresses connected per port. The total number of entries in the table would be the number of Rbridge ports on which snooping has detected an IP multicast router.

Regards,
Anil

It looks to me all we need is to maintain just one enum per port with values (ipv4/ipv6/both).
