I am wondering why you would do it that way, I would understand if you were
hiding your private addresses from the internet and there were several
routers between r1 and r2. Anyway, you do not need to hide your addressees
as long as only r1 and r2 are seeing them. You would need to use some kind
of IGP (static etc) to ensure reachability and the neighbor update source
loopback x command must be on both sides. The only time you would want to
use the non directly connected interface is if you have multiple connections
between each EBGP peer and you want to load share.

Subject: EBGP Peering over NAT
Is there anyone doing EBGP peering over NATed address ? I don't think its
possible. But just wondered if anyone has got this working.Thanks.
L0---R1-S0-----S0--R2----L0
EBGP peering between the loopbacks with NATing on the connected serial
interface.
Loopback as inside and serial as outside.
Cheers,Padhu
