please help me in finding a solution for this scenario.
A transit AS has peering with 4 upstream providers and 7 downstream customer peerings.customers are multihomed to our AS.
(i)i want to separate the transit and peering traffic(traffic between customers)
.. ie one link from customer specifically for transit traffic and other one for peering traffic alone.
(ii)how can i implement this scenario using BGP communities or any other method.
Thanks in advance
