Chapter 14 Routing Protocols

Table 84 Configuration > Network > Routing Protocol > OSPF (continued)

LABEL

DESCRIPTION

Type

Select how OSPF calculates the cost associated with routing

 

information from static routes. Choices are: Type 1 and Type 2.

 

Type 1 - cost = OSPF AS cost + external cost (Metric)

 

Type 2 - cost = external cost (Metric); the OSPF AS cost is ignored.

 

 

Metric

Type the external cost for routes provided by static routes. The metric

 

represents the “cost” of transmission for routing purposes. The way

 

this is used depends on the Type field. This value is usually the

 

average cost in the OSPF AS, and it can be between 1 and 16777214.
