Command Usage
Aggregate routes advertised to a neighbor contain an aggregator attribute. This
attribute contains an AS number and IP address. The AS number is the creator's AS
number (or confed ID in a confederation) and an IP address which is the creator’s
router-id. The set aggregator as command can be used to overwrite the
aggregator attribute in routes created locally with the aggregate-address
command, or in routes learned from a neighbor which already carry an aggregator
attribute, or to add a new aggregator attribute to a route which has no aggregator
attribute.
