Command Usage
• The metric for the default external route is used to calculate the path
cost for traffic passed from other routers within the AS out through
the ASBR.
• When you use this command to redistribute routes into a routing
domain (i.e., an Autonomous System, this router automatically
becomes an Autonomous System Boundary Router (ASBR). However,
an ASBR does not, by default, generate a default route into the routing
domain.
- If you use the always keyword, the router will advertise itself as a
default external route into the AS, even if a default external route
does not actually exist. (To define a default route, use the ip route
command.)
- 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.
