[j-nsp] BGP multihop problem - ERX310

[Paul Stewart]

Hi there.

 

Turning up an ERX-310 for a customer - it's multihomed to 2 different ISP's.

 

First ISP connection works great and has been stable for about a month now
(since it was turned up).

 

The second connection has two sessions - the first session is a /30 and is
stable. only one prefix received here which sets things up for the EBGP
multihop session on the second session. 

 

The second *session* of the second provider is where the issue is occurring
-after exactly 90 seconds the session drops.  This tells me the timers are
expiring but puzzled why.  I know it's a Cisco at the other end but
according to the folks who  manage the Cisco router it is set to 30/90 for
timers.

 

A ping test to the remote loopback doesn't show any slowdowns or loss of
packets.

 

As JunOSe and the ERX platform are "newer" for me I'm hoping it's something
obvious.. Unfortunately I'm not getting the answer so far though ;)

 

Thanks,

 

Paul
