[c-nsp] HSRP Question

[Gordon Bezzina]

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.
