interface add ip lo0 address-netmask 172.23.1.26/30

ospf create area backbone

ospf add interface to-XP4 to-area backbone

ospf add interface to-XP1 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-XP4 priority 2

ospf set interface to-XP1 priority 2

ospf set interface to-XP4 cost 2

ospf start
