[isp-bgp] Alteon AD3 and Zebra BGP flap

[Vicky Shrestha <mail@...>]

Hi,

I need help with bgp problem on  Alteon AD3 and Zebra. 

The bgp goes up and down every 2 minute or so. However both Alteon and Zebra 
has persistent connection with cisco routers.

I am running Software Version 10.0.28.6-SSH on Alteon AD3 and zebra-0.94 on a 
Linux Machine.
