ospf create area backbone
ospf add interface to-SSR4 to-area backbone
ospf add interface to-SSR1 to-area backbone
#
# This line is necessary because we want CISCO to peer with our loopback
# address.This will make sure that the loopback address gets announced
# into OSPF domain

ospf add stub-host 172.23.1.26 to-area backbone cost 1
ospf set interface to-SSR4 priority 2
ospf set interface to-SSR1 priority 2
ospf set interface to-SSR4 cost 2
