HSRP Config

rakem

Hi Guys,

Not really an exam related question but if someone could help me out i would appreciate it.

Im trying to configure HSRP for a backup link. I have the following config on the primary router;

interface FastEthernet0/0.2
encapsulation dot1Q 2
ip address 10.1.24.2 255.255.255.192
ip helper-address 10.1.24.3
standby 1 ip 10.1.24.5
standby 1 priority 110
standby 1 preempt
standby 1 track Serial0/0/0.16 30
end


my problem is on the backup router im not sure what config i should be using. If i do a show standby on the primary i get this:
FastEthernet0/0.2 - Group 1
State is Active
5 state changes, last state change 01:19:32
Virtual IP address is 10.1.24.5
Active virtual MAC address is 0000.0c07.ac01
Local virtual MAC address is 0000.0c07.ac01 (v1 default)
Hello time 3 sec, hold time 10 sec
Next hello sent in 1.944 secs
Preemption enabled
Active router is local
Standby router is unknown
Priority 110 (configured 110)
Track interface Serial0/0/0.16 state Up decrement 30
IP redundancy name is "hsrp-Fa0/0.2-1" (default)


the problem here is is says Standby router is unknown.

I have been looking on the cisco site and tryed to steps listed here:
http://www.cisco.com/warp/public/619/6.html

but that didnt seem to work... so how can i get the primary to know what the standby is?

cheers

Make sure the interfaces are in the same subnet/VLAN.

What is the config of your standby router? From the design you have shown it will need to be a member of VLAN 2 as well.

This is the interface config on the standby router... it has interfaces in all VLANS like the primary does..... its pretty much a mirror config of the primary.

interface FastEthernet0/0
no ip address
ip route-cache flow
duplex auto
speed auto
!
interface FastEthernet0/0.2
encapsulation dot1Q 2
ip address 10.1.24.1 255.255.255.192
ip helper-address 10.1.24.3
ip rip advertise 10
no snmp trap link-status
!
interface FastEthernet0/0.3
encapsulation dot1Q 3
ip address 10.1.24.69 255.255.255.192
ip helper-address 10.1.24.3
ip rip advertise 10
no snmp trap link-status
!
interface FastEthernet0/0.4
encapsulation dot1Q 4
ip address 10.1.24.134 255.255.255.192
ip helper-address 10.1.24.3
ip rip advertise 10
no snmp trap link-status

On the Fa0/0.2 you'll need atleast a "standby 1 ip 10.1.24.5" and a "standby 1 preempt" command to allow the router to fail back to the primary.
