[c-nsp] HSRP/VRRP/GLBP Dual Stack on Cat6500/Sup720 3BXL?

[Mack McBride]

HSRP and GLPB requires setting up different groups for the dual stack.
The same groups can be used on different vlans but the IPv6 has to be in a separate group from IPv4.

Well, in SXI4a, GLBP complains if I try and configure IPv6 in the same GLBP group number:

"IPv4 address already configured"

I'm not clear if I'm supposed to use a different group number or if it's just not supported. All the configuration examples I found show *just* IPv6, not a dual stack example which is what triggered my inquiry.

I haven't utilized it in v6, but SXI appears to have v6 capable HSRP and GLBP.  VRRP doesn't appear to have any v6 support.
