• To configure administrative distance for a static route, see “Adding static and null routes

to IPv6 table” (page 180).

• To configure administrative distance for OSPFv3, see “Influencing route choices by

changing the administrative distance default” (page 220).

• Metric

The routing switch uses this parameter to compare routes to identical destinations learned by

the same routing protocol. The metric is the cost of sending traffic on a given route and is

based on various criteria:

• Link conditions (bandwidth, delay, reliability)

• Organizational policies (monetary cost, autonomous systems that a packet must traverse)

Each routing protocol has its own method for computing a route's metric. For static routes,

the metric defaults to "1" and is not configurable.
