4.实验调试
（1）show ipv6 route eigrp
该命令用来查看 IPv6 EIGRP 的路由。
R1#show ipv6 route eigrp
IPv6 Routing Table - 8 entries
Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP
U - Per-user Static route, M - MIPv6
I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary
O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2
ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2
D - EIGRP, EX - EIGRP external
D 2007:26::/64 [90/21024000]
via FE80::219:55FF:FE66:6320, Serial0/0
D 2007:23::/64 [90/21536000]
via FE80::219:55FF:FE66:6320, Serial0/0
D 2008:3333::/64 [90/21664000]

以上输出说明路由表中的下一跳是对方的本地链路地址，同时 IPv6 EIGRP 也能够区分
内部路由和外部路由，外部路由代码为“EX”。
（2）show ipv6 eigrp neighbors
该命令用来查看 IPv6 EIGRP 的邻居。
