  1. What is the use case for this…?

  2. Hi Sims,

    Let’s say you have a small network with a couple of routers. One router is connected to an ISP router for Internet access. On this router, you could advertise a default route in your OSPF network.

    When there is no matching route in the routing table, the default route will be used and your traffic will be forwarded towards the ISP.

  3. Shawn,
    Yes, you can do this, sort of :slight_smile:

    Remember that a requirement for OSPF is that all members in the same area must have identical databases (and I presume that your DMVPN hub and spokes are in the same area). So the best you are going to be able to do is keep that default route from getting installed in the routing table, even though it will still be present in the OSPF database. I recommend using a prefix-list to do it. Here’s a sample:

    (config)#ip prefix-list PL_NODEFAULT deny 0.0.0.0/0
    (config)#ip prefix-list PL_NODEFAULT permit 0.0.0.0/0 le 32
    (config)

    What if we have different area and core distribution access layer .
    Where we have to put the default originate command
    Thanks

  5. I had a question.

    1. with Static default route we configure something like the following:

    ip route 0.0.0.0 0.0.0.0 xxx.DestinationAddress.xxx.xxx

    1. If it was EIGRP and we had the following manually configured default route to advertise in EIGRP we would then use the following:

    R2(config)#router eigrp AS#
    R2(config-router)#network 0.0.0.0

    with OSPF I did not see something similar is that because you just did not put in the full configuration or because OSPF just uses that statement:

    default-information originate always

    I would think it would need a manual e
