Short Answer:
It exports all routes learned by BGP (even inactive ones).

By default, BGP stores the route information it receives from update
messages in the JUNOS routing table, and the routing table exports only
active routes into BGP, which BGP then advertises to its peers. To have
the routing table export to BGP all routes learned by BGP even if the
JUNOS software did not select them to be active routes, include the
advertise-inactive statement:
advertise-inactive;
You can advertise nonactive routes for all BGP groups (at the [edit
protocols bgp] hierarchy level), for all peers in a group (at the [edit
protocols bgp group group-name] level), or for an individual peer (at
the [edit protocols bgp group group-name neighbor address] level).

Subject: [j-nsp] BGP advertise-inactive
Hello,
Simple questions:
Does BGP ``advertise-inactive'' cause JunOS to
1) advertise best BGP routes which hasn't been injected into
Master Forwarding Table table because of better routes
from other protocols, or
2) advertise all BGP routes from all Adj-RIB-In(s)?
Thank you,
Przemek
