Re: cat6509 multiple hsrp setting

Hello

This seems to be two problems , if I understand it right.

First, you can't change an secondary adress, you have to remove the old one with "no ip address 165.243.72.253 255.255.255.0 secondary".

Then you can configure the new secondary adress. Or you can do it in reverse order.

Second, you got an error message "already in use... can it be that the adress-range where 165.243.144.129 255.255.255.128 belongs, exist on another interface. Easy to check with "show ip route 165.243.144.129"
