Hi all,

My juniper router is facing an ERX router via ATM using ip address 192.168.1.1
and .2, and we are running bgp between this link.

However, our bgp is resetting pretty frequently. One of the recent cause of
resetting is due to a TCP error on both ends. In addition, what does the
statement "connection collision prefers 192.168.1.2+1926 (proto)" means?

Error messages from Juniper (JUNOS 5.0R5.1):

Does someone does any similar encounter? Any advise would be greatly
appreciated.

Thanks.
