What is iBGP?

iBGP (Internal Border Gateway Protocol) is a routing protocol used to exchange routing information within a single autonomous system (AS). It ensures that all routers within the AS have a consistent view of the external routes learned from eBGP (External BGP) peers, thus preventing routing loops and ensuring proper traffic forwarding within the AS.

iBGP Competitor Technologies

eBGP

eBGP is an alternative routing protocol to iBGP used for routing between autonomous systems, making it a competitor.

OSPF

OSPF is an Interior Gateway Protocol (IGP) that can be used as an alternative to iBGP for routing within an autonomous system.

EGP

EGP (Exterior Gateway Protocol) is an older inter-AS routing protocol that is considered a predecessor to BGP (and therefore iBGP/eBGP). It is effectively replaced by BGP now.

iBGP Complementary Technologies

MPLS RSVP-TE

MPLS RSVP-TE can be used to create traffic engineered paths within an autonomous system, which can then be used by iBGP for routing, making it a complement.
