Hi Sabrina,
I got your point, but could we say that the peers may start by deciding
who has higher ID and then leave it initiate the session.
I have faced this concept on one of the popular CCIE preparation books.
Shows and debugs in the book where confirming this. However, my tests
showed that there is no relation,
Regards
Mohamed ..

Mohamed,
how a peer can know, before initiating the session, that he has a
router ID lower than the remote side and hence it has to wait for the
other side to start?

Hi All,
Regarding the BGP peering establishment, it is supposed that the peer
with higher ID would initiate the session by sending TCP Sync (client)
while the peer with lower ID will respond (server). I was testing this
and I discovered that it is independent of the bgp router id.
If R1 with ID 10.0.0.1 has a bgp peering with R2 of ID 10.0.0.2, when I
clear the peering while I am on R1, I notice that R1 initiates the
session and R2 responds (using "debug ip packet detail" while clearing
the session). If, however, I cleared the peering while I am on R2, I
notice that R2 initiates the session !!
Has somebody else encountered this ?
Regards
Mohamed ...
