Thanks for responding. I've never done a lab with ipv6 multicast routing,
and most unicast routing examples I come across are not consistent on how
they use the broadcast keyword.
So it goes something like this (forgive me for being so visual):
Unicast routing only
------------------------------
frame map ipv6 2001:192:10:1::1 201
frame map ipv6 201 broadcast
Unicast+Multicast routing
----------------------------------------
frame map ipv6 2001:192:10:1::1 201 broadcast
frame map ipv6 201 broadcast
Thanks
Ben
