这是核心的，但是我show ip route发现路由表中只有两条信息
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
172.16.0.0/24 is subnetted, 2 subnets
C 172.16.1.0 is directly connected, Vlan10
C 172.16.156.0 is directly connected, Vlan156
vlan 20的网络为什么会没在里面，求教啊
show vlan,
show span,
show int trunk, vlan 20 no shut down 了吗？
把接口划分VLAN就可以了 把接口划分VLAN就可以了
