CAN YOU RUN HSRP BETWEEN TWO DISIMILAR IOS VERSIONS

[admin_2]

UNABLE TO RUN HSRP BETWEEN TWO ROUTERS. IOS ARE 11.2(18)-(4700) 12.0(7)T-7204.

THE ETHERNET INTERFACE ON THE 4700 LOCKS UP AS SOON AS VIRTUAL ADDRESS ADDED.

Have a look at the following:

Several ethernet controllers in low-end products can only have a single unicast MAC address in their address

filter. These are: 2500 and 4500 which use the LANCE controller, and the 800, 1000, and 1600 which use the

QUICC controller (the 1700 is not affected). On these platforms only a single HSRP group is permitted, and

the interface address is changed to be the HSRP virtual MAC address when the group becomes Active. If

HSRP is being used on multiple interfaces of this type then each interface should be configured with a

different HSRP group number (See CSCdp18132)
