Vadim,
This is a very basic BGP question and I think the only trick you have to do
is disable sync on r2 and r3 also you need:
ON R2
-----
Neighbor (R3 ip address) next-hop-self (Since this is an IBGP neighbor and
it does not know about the link between R1 and R2)
ON R3
-----
Neighbor (R2 ip add address) next-hop-self (For the same reason)
also make sure you advertise your loopback interfaces in bgp on R1 and
R4.......
What will happen is R1 will advertise the LO network to R2 since it is an
EBGP neighbor, then R2 will advertise it to R3 with a next hop address that
R3 has a connected interface to, then R3 will advertise the network to R4
through EBGP which should not need any extra configs, the opposite is true
when the LO network is advertised on R4.
Thanks

Subject: BGP - simple scenario
Hello,
I've tried scenario from Caslow book yesterday.
R1 ----- R2 ---- R3 ---- R4
AS100 200 200 400
All routers are running BGP.
How to make R1 see loopback interfaces (or networks) on R4 and to make
R4 see loopback interfaces on R1?
Thank you.
Vadim.
