carl_townshend · ‎07-09-2007

Hi all, If I want to have 2 hsrp groups on my router, do i need to have 2 interfaces with different ip addresses or 1 interface with 2 ip addresses to get that to work ?

You can setup 2 hsrp groups on the same interface

int fa0/0

ip address 10.1.1.251 255.255.255.0

ip address 10.1.2.251 255.255.255.0 secondary

standby 1 ip 10.1.1.254

standby 2 ip 10.1.2.254

If you want to have HSRP for your routers, you have to have 1 interface on each router with one ip address in the same range and configure the multiple groups under that with the Virtual IP configured in the same range. You can also create secondry ip addresses and create the HSRP group for standby addresses.

Forexample :

Router 1:

ip address 192.168.1.1 255.255.255.0

ip address 192.168.2.1 255.255.255.0 secondary

standby 1 ip 192.168.1.100

standby 2 ip 192.168.2.100

Router 2:

ip address 192.168.2.2 255.255.255.0

ip address 192.168.1.2 255.255.255.0 secondary

standby 1 ip 192.168.1.100

standby 2 ip 192.168.2.100
