[c-nsp] l3 gateway redundancy without eating three ip addresses inthe subnet

[Arie Vayner (avayner)]

Joe,

One option is to use VRRP. In VRRP the virtual IP is the actual IP used
on the physical interface of the primary router, so you will still have
to assign an IP address for each router (but this would be the case in
any solution anyway), but no need for a 3rd IP for the virtual. 

For VRRP, check:

apvrrp.html

Is there a supported cisco method to provide gateway redundancy (hsrp,
vrrp) without having to use three ip addresses from the same subnet?
slb?


Thanks,

Joe
