hybrid routing protocol

Hybrid Routing, commonly referred to as balanced-hybrid routing,
is a combination of distance-vector routing, which works by sharing
its knowledge of the entire network with its neighbors and
link-state routing which works by having the routers tell
every router on the network about its closest neighbors.

Hybrid Routing is a third classification of routing algorithm.
Hybrid routing protocols use distance-vectors for more accurate
metrics to determine the best paths to destination networks,
and report routing information only when there is a change in
the topology of the network. Hybrid routing allows for rapid
convergence but requires less processing power and memory as
compared to link-state routing.

A perfect example of a hybrid routing protocol is the Enhanced
Interior Gateway Routing Protocol (EIGRP), developed by Cisco.
