Hi All,
I have created a BGP-LU inter-domain within the same AS on my lab.
The topology is:
CE1 |----------------| PE1 |----------------| P1 |----------------| ABR1 |----------------| ABR2 |----------------| P2 |----------------| PE2 |----------------| CE2
I use static route between ABR1 & ABR2 to reach each loopback interfaces. I use loopback as BGP source.
On ABR2, i have route to 2.2.2.2(PE2) from 4.4.4.4(ABR1) as expected but the cef is unresolved :(.
router bgp 2
bgp router-id 5.5.5.5
address-family ipv4 unicast
redistribute ospf 1 match internal route-policy IP-loopback-to-asbr2 ==> contains loopbacks P2 & PE2

ABR1 is juniper.
What could be the problem here?
