Hi
I have a system with two routers one Juniper M10 and one Cisco. The routers
have a IBGP connection between each other and the cisco acts as border
router to the outside. I'm in the process of installing the juniper and
putting it as a second border router towards an IX. On the cisco I use the
"network" command to advertise our network and everything has been working
fine. The "problem" occurs whe I set up a IBGP connection between the two.
On the juniper I advertise an aggregated route and export it in the peering
with the cisco. When I do "show route 192.168.124.0" on the juniper I get:
peter at fredriksborg# run show route 192.16.124.0
inet.0: 418 destinations, 420 routes (417 active, 0 holddown, 1 hidden)
+ = Active Route, - = Last Active, * = Both
192.168.124.0/22 *[Aggregate/130] 3d 18:57:04
Reject
[BGP/170] 1d 01:50:37, MED 0, localpref
100, from 192.168.124.2
AS path: I
> to 192.168.124.10 via fe-0/1/2.0
and the best route is the one received from the cisco not he local one. On
the cisco the bet route is the local one. Have i missed something in the
configuration? As I see it, the route originated from aggregate has a
preference of 130 and should rank higher than 170 of bgp.
Rgards,
Peter
