[j-nsp] policy export in bgp question

[Piotr Marecki]

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
