Chapter 3 Configuring Open Shortest Path First (OSPF)

Configuring OSPF on the CSS

Optionally, you can define any of the following:

•The network cost for the route by including the metric option. Enter a number from 1 to 16777215. The default is 1.

•A 32-bit tag value to advertise each external route by including the tag option. The 32-bit tag value is not used by the OSPF protocol itself. You can use the tag value to communicate information between ASBRs.

•The advertised routes as ASE type1 by including the type1 option. By default, the type is ASE type2. The difference between type1 and type2 is how the cost is calculated. For a type2 ASE, only the external cost (metric) is used when comparing multiple paths to the same destination. For type1 ASE, the combination of the external cost and the cost to reach the ASBR is used.

	For example:
	(config)# ospf advertise 193.23.44.0 255.255.255.0 metric 3 type1
	To stop advertising of the route as OSPF ASE through all OSPF interfaces, enter:
	(config)# no ospf advertise 193.23.44.255.255.255.0
	The following running configuration example illustrates the ospf advertise
	command for OSPF advertising of VIP addresses and an IP address. Comments are
	preceded by an exclamation point (!).
