- If you do not use the always keyword, the router can only advertise a
default external route into the AS if the redistribute command is used
to import external routes via RIP or static routing, and such a route is
known.
• Type 1 route advertisements add the internal cost to the external route
metric. Type 2 routes do not add the internal cost metric. When
comparing Type 2 routes, the internal cost is only used as a tie-breaker if
several Type 2 routes have the same cost.
Example
This example assigns a metric of 20 to the default external route advertised
into an autonomous system, sending it as a Type 2 external metric.
