Why is EIGRP protocol independent?
Routers that are not affected by topology changes are not involved in the recomputation. The convergence time with DUAL rivals that of any other existing routing protocol. EIGRP has been extended to be network-layer-protocol independent, thereby allowing DUAL to support other protocol suites.
How EIGRP prevent routing loops?
EIGRP is a routing protocol whose strategy to prevent routing loops is based upon what is known as the EIGRP Feasibility Condition. EIGRP also makes use of another concept called Split Horizon, which we will also briefly touch on later in this article.
What does EIGRP use RTP for?
EIGRP uses Reliable Transport Protocol (RTP) to ensure that packets are delivered in order and to ensure that routers receive specific packets. A sequence number is included in each EIGRP packet.
Why is a routing loop bad?
Routing loops are bad because: Routing loops increase network traffic load by forwarding packets within the loop until they die of old age. Routing loops prevent packets from reaching their destination. Routing loops result in packet loss.
What are the four components of EIGRP?
The EIGRP Topology Table. EIGRP uses three tables: the neighbor table, the topology table, and the IP routing table. The neighbor table keeps state information regarding neighbors, and is displayed using the show ip eigrp neighbors command.
Which is better RIP or EIGRP?
However, when failure and recovery occurs the EIGRP has higher throughput than OSPF. As for bandwidth efficiency, OSPF and EIGRP has a much higher bandwidth efficiency than RIP. In every 30 seconds, RIP wastes about 0.19 Mbps, so again we prove that RIP is not suitable for large network.
How does an EIGRP router send out hello packets?
EIGRP routers send out multicast Hello packets to discover neighbors and form neighborships. An EIGRP router builds a neighbor table with Hello packets received from adjacent EIGRP routers running the same routed protocol. Only adjacent routers will exchange routing updates.
What kind of network protocols does EIGRP support?
EIGRP supports all multi-access networks, eg: Ethernet, Token Ring, FDDI, and all WAN topologies – leased lines, point-to-point links, and non-broadcast multiaccess (NBMA) topologies, eg: X.25, SMDS, ATM, and Frame Relay. – EIGRP has its roots as a distance-vector routing protocol (EIGRP is based on IGRP).
What is the multicast address of an EIGRP router?
An EIGRP router sends Hello packets out all EIGRP-enabled interfaces. The EIGRP multicast address is 224.0.0.10. An EIGRP router only establishes neighbor relationships (adjacencies) with other routers within the same autonomous system.
