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).
