1，线要连对，网关你可自己改，最后PC4能ping通PC6就行了
三层交换hcl集成包
2，配置文件
rt1
vlan 10 port g1/0/4 vlan 20 port g1/0/5 vlan 30 int g1/0/1 port link-type tr port tr pe vlan 10 20 30
rt2
vlan 10 int vlan 10 ip add 10.0.0.252 24 vlan 20 int vlan 20 ip add 20.0.0.252 24 vlan 30 int vlan 30 ip add 30.0.0.252 24 int g1/0/1 port link-type tr port tr pe vlan 10 20 30 int g1/0/2 port link-type tr port tr pe vlan 10 20 30
rt3
vlan 10 vlan 20 vlan 30 int g1/0/2 port link-type tr port tr pe vlan 10 20 30 vlan 30 port g1/0/6
最后测试主机ping通
