I have no experience with that - but doing the gedanken-experiment, I
have a question - if you do it that way, if one router fails or otherwise
hands off its VRRP address to the other router, won't the customer's BGP
session go down and have to re-connect with the new router?  Depending
on the customer's network, they may be off the air during the changeover.
