Some say it stands for DUAL, the update algorithm used by EIGRP. Some say it is because the letter E already was taken by EGP so they used the next letter in the alphabet.
If EIGRP is used with default configurations, the data will be equally distributed between two paths - A, D, B and A, C, D.
EIGRP uses port no. 88, but it is not use TCP or UDP, it's uses RTP(Reliable Transport Protocol).
this is a cisco propreitory protocol is not available for rfc
Compared to RIP, EIGRP has a lower administrative distance.
That would be a distance-vector routing protocol. Examples (taught at Cisco Academies) include RIP, IGRP (obsolete in the new version of the curriculum), and EIGRP - but those are only for IP, and there are also distance-routing protocols for other networking protocols, for example, RIP for IPX.
The bandwidth and delay interface variables are used to determine the metric in EIGRP. These values are used in the calculation of the composite metric that EIGRP uses to determine the best path to a destination.

bobo The packet is sent to discover neighbors within the EIGRP network. The packet is sent to search for network devices within an EIGRP network. The packet is used to propagate routing information within the EIGRP network. The packet is used to send an unreachable reply to another router within the EIGRP network.
we would need to redistribute ospf routes into eigrp and vice versa. redistribution will have to be done on an ASBR(autonomus system boundry router) eg: we have an ospf process wid process id 10 running and eigrp with ASN 20 running in our network redistribution on ASBR would be conf t router ospf 10 redistribute eigrp 20 subnets metric 1 and in eigrp conf t router eigrp 20 redistribute ospf metric 1 1 1 1 1 we see i used 5 ones in eigrp process to redistribute opsf into eigrp. thes 1's are metrics for eigrp namely load bandwidth delay reliability
think so it is RTP...

When you have multiple routing protocols running (e.g. RIP, OSPF, EIGRP), the one with the lowest administrative distance is used for the routing table. The metric is different; it's used within the routing protocol to determine which route is best to a certain network. EIGRP has a AD of 90. RIP has an AD of 120. Since EIGRP has a lower AD, it will be used for the routing table.
According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 1 words with the pattern D-D-A-D. That is, seven letter words with 1st letter D and 3rd letter D and 5th letter A and 7th letter D. In alphabetical order, they are: doddard
The value 2172416 highlighted in the output of the show ip eigrp topology command represents the "feasible distance" (FD) for a specific route in the EIGRP (Enhanced Interior Gateway Routing Protocol) topology table. The feasible distance is the lowest calculated metric to reach a destination network and is used by EIGRP to determine the best path for routing traffic.
Compared to RIP, EIGRP has a lower administrative distance. Compared to EIGRP, RIP has a higher metric value for the route. Compared to RIP, the EIGRP route has fewer hops. Compared to RIP, EIGRP has a faster update timer.
