# Step 1: Configure a Named EIGRP virtual instance
router eigrp TEST
# Step 2: Specify an address family along with its autonomous system number
address-family ipv4 unicast autonomous-system 1
# Step 3: Configure general EIGRP settings (network, eigrp router-id, eigrp stub, metric)

network 172.16.1.0 0.0.0.255
eigrp router-id 1.1.1.1
# Step 4: Enter Address-Family-Interface mode (default | interface-id) to apply changes to interfaces (authentication, bandwidthpercent, hello-interval, hold-time, passive-interface, split-horizon)
