CCNA / Lesson 3- EIGRP benefits

EIGRP benefits

• ·         Faster convergence (all the routers in the network will know about all routers in the network) due to no hold down timers.
• ·         Uses less BW on the network due to no periodic updates
• ·         Uses bounded and partial updates
• ·         Backup routes (feasible successor) can be installed using DUAL and the topology table. If best successor route fail, DUAL algorithm will install backup routes.
• ·         Can support IP, IPX and Apple Talk (RTP and PDM [protocol dependent modules])
• ·         Can support VLSM and CIDR (subnet mask info included in its protocol)
• ·         Capable of unequal cost load balancing (equal cost on by default) EIGRP can distribute packets out of multiple interface even of they have different metrics to a given destination network.
