Hi Onam,

The default BGP export policy is to readvertise all learned BGP routes
to all BGP speakers.

 
Thanks & Regards,
Tarique A. Nalkhande

Hello Tarique,

I have a new group of BGP, and I will provide internet to my peer, I
thought that to send full routing(All routes that I learn from my
upstream provider. IMHO) to my neighboard, I need a term Default then
accept.

Best regards.
