EIGRP Configuration Overview |
|
|
List the working interfaces on which EIGRP is enabled (based on the network commands); it omits passive interfaces. |
show ip eigrp interfaces |
|
Lists the contents of the network configuration commands for each routing process, and a list of neighbor IP addresses. |
show ip protocols |
|
Lists known neighbors; does not list neighbors for which some mismatched parameter is preventing a valid EIGRP neighbor relationship. |
show ip eigrp neighbors |
|
Lists all successor and feasible successor routes known to this router. It does not list all known topology details. |
show ip eigrp topology |
|
Lists the contents of the IP routing table, listing EIGRP-learned routes with a code of D on the left side of the output. |
show ip route |
|
EIGRP Neighbor Discovery |
EIGRP routers send Hello messages to discover potential neighboring EIGRP routers and perform basic parameter checks to determine which routers should become neighbors. |
|
EIGRP Topology Exchange |
Neighbors exchange full topology updates when the neighbor relationship comes up, and then only partial updates as needed based on changes to the network topology. |
|
EIGRP Choosing Routes |
Each router analyzes its respective EIGRP topology table, choosing the lowest-metric route to reach each subnet. |
|
EIGRP Multicast Address |
224.0.0.10 |
|
EIGRP Metric Calculation (Default K-Values) |
Metric = ((10^7/least-bandwidth) + cumulative-delay)*256 |
|
EIGRP Feature - Transport |
IP, protocol type 88 (does not use UDP or TCP). |
|
EIGRP Feature - Metric |
Based on constrained bandwidth and cumulative delay by default, and optionally load and reliability. |
|
EIGRP Feature - Hello Interval |
Interval at which a router sends EIGRP Hello messages on an interface. |
|
EIGRP Feature - Hold Timer |
Timer used to determine when a neighboring router has failed, based on a router not receiving any EIGRP messages, including Hellos, in this timer period. |
|
EIGRP Feature - Update Destination Address |
Normally sent to 224.0.0.10, with retransmissios being sent to each neighbor's unicast IP address. Can also be sent to the neighbor's unicast IP address. |
|
EIGRP Feature - Full or Partial Updates |
Full updates are used when new neighbors are discovered; otherwise, partial updates are used. |
|
EIGRP Feature - Authentication |
Supports MD5 authentication only. |
|
EIGRP Feature - VLSM/classless |
EIGRP includes the mask with each route, also allowing it to support discontiguous networks and VLSM. |
|
EIGRP Feature - Route Tags |
Allows EIGRP to tag routes as they are redistributed into EIGRP. |
|
EIGRP Feature - Next-hop field |
Supports the advertisement of routes with different next-hop router than the advertising router. |
|
EIGRP Feature - Manual Route Summarization |
Allows route summarization at any point in the EIGRP network. |
|
EIGRP Feature - Automatic Summarization |
EIGRP supports, and defaults to use, automatic route summarization at classful network boundaries. |
|
EIGRP Feature - Multiprotocol |
Supports the advertisement of IPX, AppleTalk, IPv4, and IPv6 routes.
|
