Hi, AFAIK, there is an E-BSR elected for each scope zone. Inet Address Type is not involved here. But as you rightly pointed out, this object should have read-only permission. Thanks for pointing this out. I shall fix this in next revision. Thanks & Regards, Bharat ________________________________ From: David McWalter [mailto:DMcW@dataconnection.com] Sent: Monday, March 05, 2007 8:05 PM To: LuanHaiYan; pim@ietf.org Cc: ietf-web@ietf.org; bharat_joshi Subject: RE: some doubts about draft-ietf-pim-mib-v2-09 and draft-ietf-pim-bsr-mib-01 Greetings. The PIM WG owns these drafts, so I think these questions belong on the list pim@ietf.org. 1. I don't think it's usual to add router instance information to protocol MIBs. I'm no VPN expert, so you might like to check this draft for some suggestions. http://www.ietf.org/internet-drafts/draft-ietf-l3vpn-vr-mib-04.txt 2. Yes, this is inconsistent. I believe a different E-BSR can be selected per address type as well as per-zone, so not-accessible seems correct. I think the fix is to add AddressType to the index of pimBsrElectedBSRTable. Right, Bharat?

I will appreciate it if anybody could anwser it. 1. For PIM (*,G) State Table/PIM (S,G) State Table/PIM (S,G,RPT) State Table in draft-ietf-pim-mib-v2-09, instances information is not considered, if routers can support mvpn, maybe there are same (*,G)/(S,G). how to support them? 2. In Page13 of draft-ietf-pim-bsr-mib-01, BSR Elected-BSR Table is defined as follows: ` -- The BSR Elected-BSR Table -- pimBsrElectedBSRTable OBJECT-TYPE SYNTAX SEQUENCE OF PimBsrElectedBSREntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "The (conceptual) table containing information about elected BSRs. The table contains one row for each zone for which there is an elected BSR." ::= { pimBsrObjects 4 } pimBsrElectedBSREntry OBJECT-TYPE SYNTAX PimBsrElectedBSREntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "An entry (conceptual row) in the pimBsrElectedBSRTable."
