[j-nsp] JNCIP EBGP Case Study...

[Hoogen]

Well I am working with my J-Series routers to do most topologies.. This
problem has somehow baffled me alot. Any help is greatly appreciated...

A part of topology.. I think the problem lies somewhere in this...

P1---R1---R3 (Both R1 and R3 are in 65000... and R1 is peering with P1 which
is AS 1492)

R1 receives

lab at R1# run show route receive-protocol bgp 10.0.5.254

inet.0: 65 destinations, 69 routes (63 active, 0 holddown, 4 hidden)

And then R1 sends this to R3

So far so good...

Now R3 only receives

lab at R3# run show route receive-protocol bgp 10.0.6.1

inet.0: 66 destinations, 106 routes (63 active, 0 holddown, 17 hidden)

* 192.168.100.0/24        10.0.6.1             101     101        I

__juniper_private1__.inet.0: 2 destinations, 2 routes (2 active, 0 holddown,
0 hidden)

iso.0: 1 destinations, 1 routes (1 active, 0 holddown, 0 hidden)

lab at R3#

I check to see if I have an import policy but it's not present... I am not
sure why I am not receiving any routes from R1 except for those internal
routes...

group 65000 {
    type internal;
    local-address 10.0.3.3;
    export ibgp;
    neighbor 10.0.6.1;
}

As you notice there is no policy to deny any routes.. Can someone help me
out here..
