So, based on an off-list reply, I did find why I didn't see the packets
with "monitor traffic"... "matching vrrp" only matches IPv4 VRRP.
Ooops, didn't realize that - took that off and I see the IPv6 VRRP
packets going out now.

Still don't see any incoming v6 VRRP from the other router.  I also
checked on a host on the VLAN and only see the v4 VRRP, not the v6.
