Description

Notre routeur R1 reçoit une annonce du réseau 10.30.0.0/16 depuis son routeur "cousin" chez le groupe 2. Il faudrait filtrer ce préfixe pour éviter de nous le ré-annoncer :)

florian@r1.core2> show route 10.30.0.0 detail    

inet.0: 20 destinations, 22 routes (19 active, 0 holddown, 1 hidden)
10.30.0.0/16 (2 entries, 1 announced)
        *Static Preference: 5
                Next hop type: Discard
                Next-hop reference count: 3

                Announcement bits (3): 0-KRT 3-BGP RT Background 4-Resolve tree 1 
                AS path: I

                Next hop: 10.30.254.2 via ge-0/0/0.0, selected
                State: <Ext>
                Inactive reason: Route Preference
                Local AS: 65003 Peer AS: 65002

                Task: BGP_65002.10.30.254.2+20422
                AS path: 65002 ?
                Localpref: 100
                Router ID: 10.20.1.1

En attendant on filtre cette route :

    policy-statement drop-myprefixes {
        from {
            route-filter 10.30.0.0/16 orlonger reject;
        }
    }
