Hi Tony,

This was an editing error in which the  vrIdError was not removed from the vrrpV3StatisticsProtoErrReason when vrrpv3RouterVrIdErrors was added as a global counter.

(exactly for the reason you mentioned)

vrrpv3RouterVrIdErrors should be used for counting the number of vrid errors.

Subject: [VRRP] VRRPV3-MIB protocol error trap question

I am implementing the protocol error trap in the VRRPV3 MIB and have spotted a possible hole in the MIB. I wonder if this was picked up in discussions and a work-around devised?

When an advertisement is received with an unrecognised VR ID, a protocol error trap is generated, with the object vrrpv3StatisticsProtoErrReason. This object has value vrIdError(4) in this case, but what should the index of the object be? In particular, what should the VR ID part of the index be?

I am inclined to create a variable binding with a fake OID using the unrecognised VR ID, since this will actually convey the information required (which VR ID is invalid, and the address type and ifIndex).

What, if any, discussion has taken place around this issue, and was there any conclusion reached?
