Hi,


Consider the below topology,
DUT1 ----- DUT2

Configured DUT1 as owner with vip as fe80::ca35:b8ff:fea8:82fd.
And configured DUT2 as not-owner with vip as fe80::ca35:b8ff:fea8:8212

VIP on DUT1 and DUT2 are different.

What should be the states of DUT1 & DUT2?

According to draft http://tools.ietf.org/html/draft-ietf-vrrp-ipv6-spec-07
section 7.1, 

If the packet was not generated by the address owner
(Priority does not equal 255 (decimal)), the receiver MUST drop the
packet, otherwise continue processing.

1. Does it need to compare the vip address of received packet and its vip address?
    If there are different what need to be done?

As per RFC "DUT2 should accept the packet from DUT1".
Does this mean DUT2 state should become backup?



Thanks,
Sandhya
