Well you could always assign your variable from reply after calling the function.

Or here is a change that adds a 2nd parameter for the variable to store the result.

Code:
function get_three_quad
{
   REPLY=""
   while [ -z "$REPLY" ]
   do
      printf "$1"
      read     
      if ! echo "$REPLY" | grep -qE "^((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)(\.|$)){3}$"
      then
         echo "Illegal input"
         REPLY=""
      fi
    done
    [ $# -gt 1 ] && printf -v "$2" "%s" "$REPLY"
}

get_three_quad "
Enter first three quadrants of router address (must contain three periods)
Example- xx.xxx.xx. : " PT1ADD
echo "You entered: $PT1ADD"

control_rancid(1)					      General Commands Manual						 control_rancid(1)

NAME
control_rancid - run rancid for devices of a group SYNOPSIS
control_rancid [-V] [-m mail_rcpt] [-r device_name] group DESCRIPTION
control_rancid is a sh(1) script to parse a group's router.db(5), run rancid for each of the devices, possibly re-run rancid for devices that failed collection, e-mail diffs, and e-mail error reports. The command-line options are as follows: -V Prints package name and version strings. -m mail_rcpt Specify the recipient of diff mail, which is normally rancid-<group>. The argument may be a single address, multiple comma separated addresses, or -m may be specified multiple times. -r device_name Specify the name, as it appears in the router.db, of a particular device to collect and generate diffs for. The device must be marked "up". The -r option alters the subject line of the diff mail. It will begin with <group name>/<device name> rather than just the group name alone. control_rancid is normally (and best) run via rancid-run(1) which provides a locking mechanism on a group basis and saves output in a log file for each group.

rancid-run(1), rancid.conf(5), router.db(5) 5 October 2006 control_rancid(1)
