To enable EIGRP, which of the following would you use?
1.Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
2.Router1(config-if)# ipv6 router rip 1
3.Router1(config)# ipv6 router eigrp 10
4.Router1(config-rtr)# no shutdown
5.Router1(config-if)# ipv6 eigrp 10
Answer: B
Unlike RIPng and OSPFv3, you need to configure EIGRP both from global configuration mode and from interface mode, and you have to enable the command with the no shutdown command.
