Border Gateway Protocol¶
Border Gateway Protocol (BGP) is a dynamic routing protocol used between network hosts. BGP routes between autonomous systems, connecting to defined neighbors to exchange routing information.
BGP can be used for exterior routing (ebgp) or interior routing (ibgp), routing across Internet circuits, private links, or segments of local networks.
The BGP service in TNSR is handled by FRR.
