• Add members to port channel 10:
D2(config)# interface ethernet 1/1/3
D2(conf-if-eth1/1/3)# channel-group 10
D2(conf-if-eth1/1/3)# exit
D2(config)# interface ethernet 1/1/4
D2(conf-if-eth1/1/4)# channel-group 10
D2(conf-if-eth1/1/4)# exit
• Congure OSPF on L3 side of core router:
D2(config)# router ospf 100
D2(conf-router-ospf-100)# exit
D2(config)# interface vlan 200
D2(conf-if-vl-200)# ip ospf 100 area 0.0.0.0
• Congure VLT port channel for VLAN 200:
D2(config)# interface port-channel 20
D2(conf-if-po-20)# vlt-port-channel 20
D2(conf-if-po-20)# switchport mode trunk
D2(conf-if-po-20)# switchport trunk allowed vlan 200
D2(conf-if-po-20)# exit
• Add members to port channel 20:
D2(config)# interface ethernet 1/1/5
D2(conf-if-eth1/1/5)# channel-group 20
D2(conf-if-eth1/1/5)# exit
D2(config)# interface ethernet 1/1/6
D2(conf-if-eth1/1/6)# channel-group 20
D2(conf-if-eth1/1/6)# exit
