Hi Python,
Sure dear,
Please find attachd digrams and along with configuration for both ASBRs
Just a brief regarding the topology attached
1. IOU3 = Cisco ASBR
2. Juniper 1 = ASBR
3. IOU5 = CE router
4. IOU8 and IOU9 = CE routers
5. All CE routers has same AS=65000
6. Juniper AS = 10991
7. Cisco ASBR AS = 13789
Problem, Cisco ASBR is advertising correct routing to Juniper ASBR, however Juniper forwards the routes only to IOU9 and not IOU8.
Simillary, Juniper is receiving the routes from both CEs ( IOU8 and IOU9) however it forwards routes to Cisco NNI ( ASBR ) from IOU9 only
