单臂路由不通，求大神

我按照你的组网和配置试了一遍，完全没问题啊，你的问题不在于配置，应该是virtualbox或者模拟器有问题。

【终结vlan路由器】

# interface GigabitEthernet0/0.1

 ip address 192.168.10.1 255.255.255.0

 vlan-type dot1q vid 10

 vlan-termination broadcast enable

 # 

interface GigabitEthernet0/0.2

 ip address 192.168.20.1 255.255.255.0

 vlan-type dot1q vid 20

 vlan-termination broadcast enable

【交换机配置】

# vlan 10

#

 vlan 20 

#

interface GigabitEthernet1/0/1

 port link-mode bridge

 port link-type trunk

 port trunk permit vlan all

 combo enable fiber 

# 

interface GigabitEthernet1/0/2--连PC1

 port link-mode bridge

 port access vlan 10

 combo enable fiber 

# 

interface GigabitEthernet1/0/3--连PC2

 port link-mode bridge

 port access vlan 20

 combo enable fiber

【结果】
