HSRP vs VRRP for IPv6 on IOS-XE - rekindling an old flame

Tue Aug 21 06:38:25 UTC 2012

Any idea what to do if you want to use a FHRP for >255 subinterfaces?
HSRP allows you to use the same group number under multiple subinterfaces, while VRRP doesn't.
I don't know if this is only a Cisco limitation (giving preference to their child).
