    Anyone got experience in bgp route reflector in ArubaOS-CX?

    got a vsx cluster configuret and got 2 neighbors that i configured with route reflector client, but the routes switch B get for router A dont goes to switch C.

    B is the RR and A & C i RR clients.

    I can see all routes on B from A but nothing on C, i can see the BGP neighbor is up for both.

    We run vrf but that shouldn't do anything.

    Router A is a RR.

    The only thing i can see is the neightbour x.x.x.x route-reflector-client command, do i need anything else? 

    I can see in the bgp neighbor thats it says that C is a RR client but no routes is exchanged

    Thx.

    Hi its just regular routing, we allready use iBGP in our environment

     

     added a simple topology on what im doing.

     

    here's a sample of the config

     

    router bgp X
    bgp router-id X.X.X.X
    timers bgp 30 90
    !
    vrf XXXX
    bgp router-id X.X.X.X
    neighbor X.X.X.X remote-as X
    neighbor X.X.X.X password ciphertext XXXXXX
    address-family ipv4 unicast
    neighbor X.X.X.X activate
    neighbor X.X.X.X route-reflector-client
    exit-address-family

    i think i found the issue, its a next hop self, see the routes in the bgp but they are not selected as they don't know the next hop, im trying to fix that with the next-hop-self cmd, ill update the post later.
