Internal BGP (iBGP) peers operate within a single Autonomous System (AS). External BGP (eBGP) peers operate between autonomous systems. Border routers are on AS boundaries and exchange information with other autonomous systems; the primary function of border routers is distributing routes. Internal ...
The AS that receives the MED attribute will not advertise it to any third AS. Similar to the metric used by an IGP, the MED is used to determine the optimal route when traffic enters an AS. If the router running BGP obtains multiple routes from different EBGP peers and these routes have...
Each VPN instance can be considered as a virtual device, which maintains an independent address space and has one or more interfaces connected to the device. In BGP/MPLS IP VPN standards, a VPN instance is called a per-site forwarding table. As the name suggests, VPN instances correspond to...
