[c-nsp] HSRP Question

[Paul Stewart]

Thanks..

But if I create a static route, then during failover nothing will work
right?  Because it's pointed specifically to an interface then?

We run OSPF, so would this not work without static routing as long as
we're "redistribute connected" ?

Thanks,

Paul

Hi Paul,

The HSRP ip can be outside the subnet but for this to work you need to
create a static route to the new subnet.

EG.

interface Ethernet0/0/3.1
 encapsulation dot1Q 101
 ip address 192.168.100.21 255.255.255.248  no snmp trap link-status
standby 1 ip 192.168.1.254  standby 1 timers 5 15  standby 1 priority
110  standby 1 preempt !

And later on

ip route 192.168.1.0 255.255.255.0 Ethernet0/0/3.1 


hope it helps.
