Re: HSRP config

You can setup multiple HSRP groups on the same interface in different subnets much the same way you can setup secondary ip addresses.

If you had two subnets 10.1.1.0 and 10.1.2.0 that you wanted to setup hsrp for on the same router interface you could do the following:

Router 1:

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

Router 2:

ip address 10.1.2.252 255.255.255.0

ip address 10.1.1.252 255.255.255.0 secondary

standby 1 ip 10.1.1.254

standby 2 ip 10.1.2.254

You can change the priority, timers and prempt settings of each group independently allowing Router 1 to be active in group 1 and router 2 to be active in group 2 at the same time. The following is a case study on HSRP: http://www.cisco.com/en/US/tech/tk1330/technologies_design_guide_chapter09186a008066670b.html

For more information I suggest the BCMSN self study guide from Cisco Press

Re: HSRP config

hi

yes u can configure HRSP with 2 diffrent ip subnet by 2 ways

1. make 2 sub interfaces and use hsrp on that , use also vlan if required

2. as define in this forom ,

but why do u require to diffrent ip to connect router give the ip given by the isp to serial interface and use private ip address on router lan interface as well as on firewall , so that is the way u can reduce the complexcity
