Task 11: Examine the EIGRP Topology Table
View the EIGRP topology table.
Step 1.
Use the show ip eigrp topology command to view the EIGRP topology table on R2:
R2# show ip eigrp topology
IP-EIGRP Topology Table for AS 1
Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
r - Reply status
P 172.16.2.0/24, 1 successors, FD is 28160
via Connected, FastEthernet0/0
P 172.16.3.0/30, 1 successors, FD is 40512000
via Connected, Serial0/0/0
P 192.168.10.8/30, 1 successors, FD is 3011840
via Connected, Serial0/0/1
P 172.16.0.0/16, 1 successors, FD is 28160
via Summary (28160/0), Null0
P 192.168.10.0/24, 1 successors, FD is 3011840
via Summary (3011840/0), Null0
P 172.16.1.0/24, 1 successors, FD is 40514560
via 172.16.3.1 (40514560/28160), Serial0/0/0
P 192.168.1.0/24, 1 successors, FD is 3014400
via 192.168.10.10 (3014400/28160), Serial0/0/1
via 172.16.3.1 (41026560/2172416), Serial0/0/0
P 192.168.10.4/30, 1 successors, FD is 3523840
via 192.168.10.10 (3523840/2169856), Serial0/0/1
View detailed EIGRP topology information.
Step 2.
Use the network parameter of the show ip eigrp topology command to view detailed
EIGRP topology information for the 192.16.1.0 network.
R2# show ip eigrp topology 192.168.1.0
