Command
Show IP EIGRP Topology
Use
This command shows EIGRP topology information on the router. This information includes the advertised and feasible distance for all paths as well as the successors. This is especially useful when calculating variance.
Syntax
Router#show ip eigrp topology
Example
In the below example we see the EIGRP topology information on R2
R2(config)#do show ip eigrp topology IP-EIGRP Topology Table for AS(100)/ID(2.2.2.2) Codes: P – Passive, A – Active, U – Update, Q – Query, R – Reply, r – reply Status, s – sia Status P 1.1.1.1/32, 1 successors, FD is 156160 via 10.1.1.1 (156160/128256), FastEthernet0/0 P 3.3.3.3/32, 1 successors, FD is 156160 via 10.2.2.3 (156160/128256), FastEthernet1/0 P 2.2.2.2/32, 1 successors, FD is 128256 via Connected, Loopback0 P 1.3.3.3/32, 1 successors, FD is 156160 via 10.1.1.1 (156160/128256), FastEthernet0/0 P 1.2.2.2/32, 1 successors, FD is 156160 via 10.1.1.1 (156160/128256), FastEthernet0/0 P 10.1.1.0/24, 1 successors, FD is 28160 via Connected, FastEthernet0/0 P 10.4.4.0/24, 2 successors, FD is 2172416 via 10.1.1.1 (2172416/2169856), FastEthernet0/0 via 10.2.2.3 (2172416/2169856), FastEthernet1/0 P 10.2.2.0/24, 1 successors, FD is 28160 via Connected, FastEthernet1/0
