HSRP problem

I have two 7206vxr's which I'm attempting to setup w/ HSRP.


On routerA I have the following setup - FYI the two routers can ping each others "real" ip address and both "real" ips reside on the same subnet and vlan.


RouterA

interface Port-channel1.1

description etherchannel link with vlan1

encapsulation dot1Q 1 native

ip address x.x.x.x 255.255.255.240

standby 1 ip <shared hsrp address>

standby 1 priority 100


RouterB

interface Port-channel1.1

description etherchannel link with vlan1

encapsulation dot1Q 1 native

ip address x.x.x.x 255.255.255.240

standby 1 ip <shared hsrp address>

standby 1 priority 90


Afterwards a 'show standby' on routerA yields the following


Port-channel1.1 - Group 1

Local state is Active, priority 100

Hellotime 3 sec, holdtime 10 sec

Next hello sent in 2.016

Virtual IP address is <hsrp address> configured

Active router is local

Standby router is <router_b ip>, priority 90 expires in 7.336

Virtual mac address is 0000.0c07.ac01

2 state changes, last state change 00:13:15

IP redundancy name is "hsrp-Po1.1-1" (default)


and on routerB


Port-channel1.1 - Group 1

Local state is Standby, priority 90

Hellotime 3 sec, holdtime 10 sec

Next hello sent in 1.662

Virtual IP address is <hrsp address> configured

Active router is <router_a ip>, priority 100 expires in 7.540

Standby router is local

1 state changes, last state change 00:10:19

IP redundancy name is "hsrp-Po1.1-1" (default)


After looking over the above commands I thought I was in business - I pinged the HSRP address from router_a and got no replies - same from router_b.


I then looked at the arp tables on router_a


Internet <hsrp ip> - 0000.0c07.ac01 ARPA Port-channel1.1


The HSRP ip address WAS present in the arp table. From their I tried to ping the hsrp ip from various hosts on the network - still nothing. Afterwards a 'nmap -P0 209.94.42.100' to see if that hsrp ip responded at all to a port scan.. Still nothing...


I've checked for obvious problems - typos and such. Still I'm coming up short.

I don't know if you can do this but very infrequently a shut and no shut on the interface is needed to wake it up. Can you try this?

From the routers, enter the "show ip interface brief" and verify that the Port-channel1.1 interfaces are up up. If they are in any status other than up up (down down, up down, etc.), you need to verify these interfaces before HSRP will work properly.

Do you have a route to that network that HSRP is configured on?

Sorry for the delay in responding. After a day of cooling off and regrouping I added the HSRP group. Same problem - I then did a


clear arp-cache


that must of jarred something loose... Anyhow - things are working.


The problem seems at least semi-common
