[j-nsp] Hidden IPv4 iBGP routes

[Harry Reynolds]

Yes, I believe that is enough to cause your issue. 

I believe that independent domain might help with the global as loop check, but it too is global and needs to be carefully tested.

Else use as loops, which should also be tested. ;) Adding will flap bgp IIRC.

We do have the following configured under bgp:

group SomeGroupName {
    type external;
    traceoptions {
        file ipv4-ebgp-customer-logs size 10m files 10;
        flag state;
    }
    description "SomeGroup";
    family inet {
        unicast;
    }
    remove-private;
    local-as XXXXX private;
}

I wish I could post that stuff without editing.  hehe  Is that enough
to break things? And if so, what is the fix?

Thanks!
