lines in the router SSR6 configuration file configure OSPF:
The following lines in the Cisco router configure OSPF:
The following lines in the SSR6 set up peering with the Cisco router using the Routing
group type.
#
# Create a secondary address for the loopback interface
#
interface add ip lo0 address-netmask 172.23.1.26/30
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
ospf start
The following lines on the CISCO 4500 configures it for OSPF.
