VRRP (IP packets addressed to the IP address of the virtual router owner) ghiggia 01-19-05

If I have a Virtual Router with VRID=1 and virtual and real IP
address=10.1.1.254, this is the owner.
If an host ping the address 10.1.1.254 when the owner is active and
master the ping reply must have the source MAC address
00-00-5E-00-01-01. Is it correct?
The other MAC that can me used is the real MAC address of the
interface, but this seems not compliant with VRRP RFC.

Regards

That's what the RFC says. 00-00-5E-00-01-VRID .

:The other MAC that can me used is the real MAC address of the
:interface, but this seems not compliant with VRRP RFC.

Hey, I only know what the RFC tells us. But you've read the RFC,
so I'm not sure why you are asking this question. Is there something
particular about using the virtual MAC that is troubling you?
Some aspect of it that you do not understand the RFC on? Or were you
looking for a way to impliment VRRP -without- using the correct
virtual MAC, such as for use in a setup where you could generate
fairly arbitrary IP packets but were not able to control the source
MAC ?
