I have two WAN routers, each connected to a separate ISP. I'm advertising 200.200.200.0/24 over BGP to both. My AS is 200200. Both of these WAN routers are connected to a switch fabric with my LAN ...

Abstract: Open Shortest Path First (OSPF) traffic engineering (TE) is intended to bring long-awaited traffic management capabilities into IP networks, which still rely on today's prevailing routing ...

Equal-cost multi-path allows a router to insert more than one path to a destination in the routing table to enable load balancing. Here's how ECMP works and how to configure it in OSPF. Equal-cost ...
