EIGRP: AS 100 across a three-router chain
- Routing
- Intermediate
- 14 min
- 4 steps
- Cisco IOS-style
Three routers in a line run EIGRP AS 100. Enable EIGRP on each router, declare the networks via network statements, and verify that every router learns the others' subnets.

Scenario
EIGRP (RFC 7868) is Cisco's distance-vector protocol with the DUAL algorithm. Activation is two-step: enter the process with the AS number, then add network statements that auto-activate matching interfaces (Cisco wildcard match).
Topology
3 × router · Cisco IOS-style
R1— routerR2— routerR3— router
What you will do
On R1, start EIGRP in AS 100 and announce 10.0.0.0/30 (wildcard 0.0.0.3).
On R2, start EIGRP AS 100 and announce both /30 subnets.
On R3, EIGRP AS 100 + 10.0.0.4/30.
From R1 ping R3 (10.0.0.6) — should route through R2.
