Configure generated routes, which are used as routes of last resort.

  • (active | passive);
  • as-path <as-path> <origin (egp | igp | incomplete)> <atomic-aggregate> <aggregator as-number in-address>;
  • community [ community-ids ];
  • discard;
  • (brief | full);
  • (metric | metric2 | metric3 | metric4) value <type type>;
  • (preference | preference2 | color | color2) preference <type type>;
  • tag string;

defaults—Specify global generated route options. These options only set default attributes inherited by all newly created generated routes. These are treated as global defaults and apply to all the generated routes you configure in the generate statement. This part of the generate statement is optional.

route destination-prefix—Configure a non-default generated route:

  • default—For the default route to the destination. This is equivalent to specifying an IP address of
  • destination-prefix/prefix-length—/destination-prefix is the network portion of the IP address, and prefix-length is the destination prefix length.

The policy statement is explained separately.
