cert question in Cisco
Posted on 2014-10-05
You are working at an ISP that has two upstream 10Gbps connections to two different providers. BGP is used to propagate the routes for each connection. The ISP has around 16,000 IP addresses over a multiple /19 and /20 prefixes, all announced from your own AS. Your total bandwidth needs to top out at 13Gbps but the requirement is to evenly balance the incoming and outgoing traffic over the two links.
a) How would you balance the incoming and outgoing traffic evenly, or as evenly as possible, over the two connections?
