yes , you should add also policy that exports aggregate to your
ibgp-mesh.However you shall note that your last term
is reject so i would suggest make another policy statement without reject
as last statement (unless you don't want you ebgp routes being propagate to
ibgp peers)

Subject: [j-nsp] policy export in bgp question


Hello everyone
I am trying to configure a juniper for announcing our network space(like
network statements in cisco). This router has an ebgp connection to our
transit provider and its also participating in ibgp mesh. Right now I have
only one cisco that have network statements in the mesh of 15 routers and I
want to use the juniper as a back up in case the cisco fails. I have
created the policy for aggregrate routes and have imported it into my ebgp
group. My question is that do I need to import that policy into my IBGP
group also ? Here is what my policy looks like.

routing-options {
aggregate {
route x.x.x.x/x passive;
}
}

policy-options policy statement aggeregate {
term agg {
from route-filter x.x.x.x/x exact;
then accept;
}
term default
then reject
}
protocols {
bgp {
group transit {
export aggregate
}
}
group ibgp-mesh
export ?
}

Thanks in advance,
Wajahat

Also to simplify you policies if you have more than one aggregate you
can use the match 'from protocol aggregate;'
