IGP Insights | Sumble

What is IGP?

Interior Gateway Protocols (IGPs) are used for exchanging routing information within an autonomous system. Common examples include RIP, OSPF, and EIGRP. They enable routers within a network to learn about the topology and determine the best paths for forwarding data packets.

What other technologies are related to IGP?

IGP Competitor Technologies

EGP

Exterior Gateway Protocol (EGP) is a routing protocol used to exchange data between different autonomous systems, making it a competitor to IGP which operates within a single autonomous system.

BGP

Border Gateway Protocol (BGP) is an exterior gateway protocol used for routing between autonomous systems, contrasting with IGP's intra-AS routing. Therefore, it is a competitor.

IGP Complementary Technologies

IP VPN

IP VPNs can utilize IGPs for routing within the VPN and rely on them for connectivity between sites. Thus, they are complementary.

MPLS

MPLS relies on IGP protocols to establish the underlying IP connectivity over which MPLS labels are distributed. Therefore, it's complementary.

LDP

Label Distribution Protocol (LDP) is used in MPLS networks to distribute labels, often working in conjunction with IGP protocols to establish paths. Therefore, it is complementary.
