HSRP - Both Active in slave groups

Hi all,

I work at an ISP and I want to implement HSRP to give some protection to my clients.

All clients are connected to 2 routers(RT02 and RT03) over a single interface on each router. Clients are separated by subinterface.

To minimize any effect in the router processor due to the quantity of vlans in use, i was testing HSRP with command "standby follow".

I've choosed a vlan of control to exchange messages of HSRP protocol and set the others vlans to follow this master vlan.

The HSRP works fine but when i do a shut on the master vlan that is in the active router, the state of all slave vlan doesn't change.

Output bellow:

Before shut

  Virtual IP address is 186.219.34.97

Followed by groups:

    Te2/1.2703 Grp 2703 Active - master disabled

    Te2/1.2704 Grp 2704 Active - master disabled

This condition is normal? This means that all slave group are in standby state on RT03?

I mean, is the HSRP working properly?

Can you post the HSRP config for both routers?

Sorry, it is a .zip file and I cannot open them on my workstation for security purposes, mainly because it cannot inspect the zip file without unpackaging it.  Are you able to just cut and paste the hsrp config specifics?
