Hi,

The question seems want to standby the MAC address rather than IP address;
I don't think this can be achieved. What the "mac-address" is just for
manully assign a MAC address for the virtual router other then pre-assigned
0000.000c.07acXX.

Thx,

You are missing a command for your standby group? Think IP!!

The virtual MAC is so the arp/mac or cam tables are steady.

 R1-(e0 1.1.1.1)----(e0 1.1.1.2)-R2

-R1 is a Active & R2 is a Standby.
-The virtual mac-address of 0000.0c07.eeee is used for the standby address
****

My Solution

R1>

interface Ethernet0
 ip address 1.1.1.1 255.255.255.0
 standby 1 priority 125 preempt
 standby 1 mac-address 0000.0c07.eeee

R2>

interface Ethernet0
 ip address 1.1.1.2 255.255.255.0
 standby 1 priority 120 preempt
 standby 1 mac-address 0000.0c07.eeee

=>But R1 isn't be Active & R2 isn't be Standby.
  & The virtual mac-address have no effection to my HSRP.!!!

How can i fix this problom ????
