Blog by Taras Matselyukh – CTO and Principal Consultant at Opt/Net Consulting B.V.
Hashtags: #BGPRouteServerJUNOS

In this section of blog I will show you how to achieve all of the requirements set forth in the beginning of this series of the blog and make a real BGP Route-Server out of your older JUNOS router.

Proverbs and reality
