Who is BGP?

“Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information between autonomous systems (AS) on the Internet.

What is a route leak?

A route leak is the propagation of routing announcement(s) beyond their intended scope. That is, an announcement from an Autonomous System (AS) of a learned BGP route to another AS is in violation of the intended policies of the receiver, the sender, and/or one of the ASes along the preceding AS path.

Is BGP Layer 3 or 4?

BGP is a Layer 4 protocol that sits on top of TCP. It is much simpler than OSPF, because it doesn’t have to worry about the things TCP will handle. Peers that have been manually configured to exchange routing information will form a TCP connection and begin speaking BGP.

What is VRF route leaking?

Inter-VRF local route leaking allows the user to export and import routes from one VRF to another on the same device. Accessing shared resources allows one to export the route target of the shared services VRF into all customer VRFs, and allows the shared services VRF to import route targets from customers A and B.

What is the difference between VRF and VRF Lite?

VRF (virtual routing and forwarding) is a core technology of MPLS which allows a service provider to provide BGP routing to many customer VPNs while isolating each customer’s routing tables. VRF lite is used to separate router interfaces within the routing tables. It can be used when multiple customers share a router.
