To help reduce the memory requirements of receiving full BGP updates (BGP updates that include all routes), some ISPs give you three basic options for what routes the ISP advertises: * Default route only: The ISP advertises a default route with BGP, but no other routes. Juniper QFX10000 Hardware Architecture. Today’s command is “bgp bestpath as-path multipath-relax”, which is actually hidden in IOS. The JUNOS BGP multipath supports the following: Load balancing across multiple links between two routers belonging to different ASs Load balancing across a common subnet or multiple subnets to different routers belonging to the same peer AS. The Juniper Networks® SSG140 Secure Services Gateway is a high-performance security platform for branch offices and small/medium sized standalone businesses that want to stop internal and external attacks, prevent unauthorized access, and achieve regulatory compliance. if the routes travers several different AS, even the AS path length is same, it will not be load balance. Moreover you need to define also the maximum number of Sites. Introduction. BGP - CONFIGURATION GUIDE V 11.
