[rancid] RANCID Router Login

Hello,

Our organization uses RANCID for gathering data from our Cisco routers, but we recently faced an issue with a change we're trying to make.

We simply want to change what the address that the scripts use to log into the routers. Let's say in the routers.db file we have:
Router1:cisco:up
Router2:cisco:up
Router3:cisco:up

We'd like to change it to:
Router1.XYZ:cisco:up
Router2.XYZ:cisco:up
Router3.XYZ:cisco:up


We didn't want to change the actual router names in the routers.db file, since this would most likely have other side effects like modifying the CVS. We tried changing clogin:750(ish) from
if {[login $router $ruser $userpswd $passwd $enapasswd $cmethod $cyphertype]} {

to
if {[login $router.XYZ $ruser $userpswd $passwd $enapasswd $cmethod $cyphertype]} {

However, by watching the tcpdump output, we see that it's still reaching out to the original address.

Do you have any ideas that could help us?

Thanks,
Axel Munoz-Persinger
