Chapter 3 Configuring Open Shortest Path First (OSPF)
Configuring OSPF on the CSS
Define an address range by specifying an IP address and subnet mask that
represents networks in the area being summarized.
Enter the IP address and
subnet mask in dotted-decimal notation (for example, 192.168.128.0
255.255.224.0). You can also enter the mask in CIDR bit-count notation format
(for example, /24).
To configure the CSS as an ABR with an area ID of 0.1.0.1 with a collection of
destinations between 192.168.0.0 and 192.168.255.255, enter:
(config)# no ospf enable
(config)# ospf range 0.1.0.1 192.168.0.0 255.255.0.0
To remove the range, enter:
(config)# no ospf range 0.1.0.1 192.168.0.0 255.255.0.0
By default, the ABR advertises this range. If you want to hide the range from the
rest of the AS, include the block option. For example:
(config)# ospf range 0.1.0.1 192.168.0.0 255.255.0.0 block
Configuring the CSS as an Autonomous System Boundary Router
If you want the CSS to be an ASBR that exchanges routing information with
routers belonging to other autonomous systems, use the ospf as-boundary
command. Disable OSPF before you enter the ospf as-boundary command.
For example:
(config)# no ospf enable
(config)# ospf as-boundary
To remove the CSS as an AS boundary router, enter:
(config)# no ospf as-boundary
