EIGRP
Intro
Enhanced Interior Gateway Routing Protocol
Was Cisco proprietary, but Cisco has now published it openly so other vendors can implement it on their equipment.
Considered an 'advanced'/'hybrid' distance vector routing protocol.
Much faster than RIP in reacting to changes in the network.
Does not have the 15 'hop-count' limit of RIP.
Is the only IGP that can perform unequal-cost load-balancing (by default it performs ECMP load-balancing over 4 paths like RIP).
