Hi, you mean you do something like that:

r1:

int lo0

ip add 1.1.1.1 255.255.255.0

int s1/0

ip add 200.1.1.1 255.255.255.0

no sh

ip route 2.2.2.0 255.255.255.0 s1/0

router bgp 100

nei 2.2.2.2 remote-as 200

nei 2.2.2.2 update-source lo0

nei 2.2.2.2 ebgp-multihop 2

r2:

int lo0

ip add 2.2.2.2 255.255.255.0

int s1/0

ip add 200.1.1.2 255.255.255.0

no sh

ip route 1.1.1.0 255.255.255.0 s1/0

router bgp 200

nei 1.1.1.1 remote-as 100

nei1.1.1.1 update-source lo0

nei 1.1.1.1 ebgp-multihop 2

then there will only be one eBGP peering and that is normal behavior.

Regards.
