Hi Kaylan,

We have cases where it is more efficient to search for all VRs within an IfIndex if the ordering is

{ vrrpOperationsInetAddrType, ifIndex, vrrpOperationsVrId}

and

{vrrpOperationsInetAddrType, ifIndex, vrrpOperationsVrId, vrrpAssociatedIpAddr}

This would still satisfy Bert's request (vrrpOperationsInetAddrType as the first one). Is it too late to request this as a change?

Thanks,
Georges

Hi Prakash,

    The order was as you suggested in the initial drafts. This was discussed in one of the ietf meetings and I think

Wijnen, Bert suggested and every one agreed to change the order to what it is right now.

The rational (as I remember it) for vrrpOperationsInetAddrType to be first is that operators would like to walk on IPv4 or IPv6 virtual routers with out actually knowing vrids or ifindexes.

I do not remember the exact reason of the other part of the order. Am CCing the WG to see if Mukesh or anyone else

remembers the discussion.

Thanks,
Kalyan

Subject: indexing order in vrrpAssociatedIpAddrTable in draft-ietf-vrrp-unified-mib-06.txt

Kalyan,

Let me introduce myself. I am part of the team which is implementing draft-ietf-vrrp-unified-mib-06.txt here at Alcatel-Lucent.

And I have a question on the indexing order in vrrpAssociatedIpAddrTable.

From original VRRP-MIB, here is the indexing order:

vrrpAssoIpAddrEntry OBJECT-TYPE

    INDEX    { ifIndex, vrrpOperVrId, vrrpAssoIpAddr }

From the new draft which support IPv6, here is the indexing order:

vrrpAssociatedIpAddrEntry OBJECT-TYPE

    INDEX    { vrrpOperationsInetAddrType, vrrpOperationsVrId,
               ifIndex, vrrpAssociatedIpAddr }

I would like to have vrrpOperationsInetAddrType and vrrpAssociatedIpAddr objects together which is typically how ipv6 support is generally implemented. Our utility routines always assume these to be together.

So I would prefer the following INDEX for vrrpAssociatedIpAddrTable:

    INDEX    { vrrpOperationsVrId, ifIndex, vrrpOperationsInetAddrType, vrrpAssociatedIpAddr }

Let me know your thoughts on this.

Thanks.
