It has been my experience when using HSRP with 6500 MSFC's to use the
"standy use-bia" command and it
eliminated this problem. I do not recall if this was a known bug or not.

Also it really does no good to specify your group as the same vlan #. For
instance, what if you wanted multiple
standby addresses on the same VLAN? I would start with "standby 1" like so.

interface Vlan1
 ip address 10.1.1.2 255.255.0.0
 ip access-group 199 in
 ip helper-address 10.88.1.1
 ip helper-address 10.88.1.180
 no ip redirects
 ip ospf priority 200
 standby 1 ip 10.1.1.1
 standby 1 timers 1 3
 standby 1 priority 200
 standby 1 preempt
 standby 1 authentication vlan
 standby 2 ip 10.1.32.97
 standby 2 timers 1 3
 standby 2 priority 200
 standby 2 preempt
 standby 2 authentication vlan
 standby 3 ip 10.1.32.96
 standby 3 timers 1 3
 standby 3 priority 200
 standby 3 preempt
 standby 3 authentication vlan
 standby 4 ip 10.1.1.36
 standby 4 timers 1 3
 standby 4 priority 200
 standby 4 preempt
 standby 4 authentication vlan
 standby 5 ip 10.1.15.2
 standby 5 timers 1 3
 standby 5 priority 200
 standby 5 preempt
 standby 5 authentication vlan
 standby 6 ip 10.1.15.78
 standby 6 timers 1 3
 standby 6 priority 200
 standby 6 preempt
 standby 6 authentication vlan
 standby 7 ip 10.1.32.98
 standby 7 timers 1 3
 standby 7 priority 200
 standby 7 preempt
 standby 7 authentication vlan

Subject: question about hsrp and dual mfsc's

hi,
have two msfc's which have previously been configured for hsrp multiple
vlans
in the default group.
i have heard and have seen some unclear information about configuring hsrp
with a group# = to
the vlan.
i the past during a failover event i have seen "duplicate address" messages.
i had seen information of this, but it mostly related to non-cisco hsrp
devices.
 this months packet had a brief question about this.
anyone know of any specific documentation related to this ?

also i tryed to add somthing like

interface Vlan10
 description vlan10
 ip address 172.16.10.2 255.255.255.0
 ip helper-address xxx
 ip helper-address xxx
 no ip redirects
 no ip mroute-cache
 standby 10 priority 105 preempt
 standby 10 ip 172.16.10.1

it seems to keep the group0 entry ?
how do i get rid of it in order to get it to use the group xxx entry ?
do i have to shut - no shut the interface ?
reload the router ?
remove and re-add the vlan int ?
