Basic EIGRP Configuration

ip routing

router eigrp 10
eigrp router-id 172.16.1.1
network 0.0.0.0
passive-interface default
no passive-interface vlan 10
no passive-interface vlan 20
redistribute static

Adjusting metrics (to prefer vlan 20)
int vlan 10
delay 10

*****************************

ipv6 unicast-routing

ipv6 router eigrp 10
passive-interface default
no passive-interface vlan 10
no passive-interface vlan 20
redistribute static metric 1000000 100 255 1 1500
metric = bandwidth, delay, reliability, load, mtu

(all networks per interface)
int vlan 10
ip address 10.1.1.1 255.255.255.0
ipv6 eigrp 10
delay 10

int vlan 20
ip address 10.1.2.1 255.255.255.0
ipv6 eigrp 20
