Which protocol is known for its hybrid routing capability?

The protocol recognized for its hybrid routing capability is Enhanced Interior Gateway Routing Protocol (EIGRP). EIGRP uniquely combines features of both distance vector and link-state routing protocols. This hybrid nature allows it to provide fast convergence and efficient routing by using distance vector methods like path cost, while also utilizing link-state techniques for the dissemination of routing information.

EIGRP maintains a topology table and uses the Diffusing Update Algorithm (DUAL) to ensure that routers have both primary and backup routes to a destination, enhancing its resilience and efficiency in path selection. This blend of methodologies enables EIGRP to adapt to network changes swiftly while also maintaining less overhead compared to purely link-state protocols.

In contrast, Open Shortest Path First (OSPF) is a link-state protocol, while Routing Information Protocol (RIP) operates as a distance vector protocol. Border Gateway Protocol (BGP) is primarily used for routing between different autonomous systems on the internet and is classified as a path vector protocol. None of these protocols exhibit the same hybrid functionality that characterizes EIGRP.
