  1. Hi Andrew,

    Thanks.

    Do we have any examples on Dual HUB along with links to two service providers from each HUB. Same thing from spoke router as well.

  2. Just wondering why you use the route-map for the neighbours outbound?

    If you use the “network 0.0.0.0 mask 0.0.0.0” in the BGP routing process, why do you also need to create a route-map specifying the same thing again?

  3. Hello Chris,

    Good question. If you use eBGP and the same AS number on the spoke routers then the route-map isn’t really needed since the spoke routers will deny prefixes with their own AS number. On the other hand, the hub will advertise those prefixes so a route-map isn’t a bad idea…it ensures that we really only advertise the default route.

    If you use eBGP and different AS numbers on the spoke routers, the route-map is a good idea.

    With iBGP, it’s also not really needed since because of split horizon, the hub won’t advertise a prefix from one spoke to another
