模拟两条出链路负载均衡，断开一条后，上传只有一条的一半，是不是有什么没配置？

模拟两条出链路负载均衡，断开一条后，上传只有一条的一半，是不是有什么没配置？

两条线路都在的时候，测速下载2M，上传2M

只用一条线路的时候，测速下在1M，上传0.5M

#1.接口IP配置

#

interface GigabitEthernet1/0/0

 ip address 192.168.1.1 255.255.255.0

#

interface GigabitEthernet1/0/1

 ip address 10.10.10.2 255.255.255.252

 nat outbound

#

interface GigabitEthernet1/0/2

 ip address 20.20.20.2 255.255.255.252

 nat outbound

#

#2.接口加了安全域

#

security-zone name Management

undo  import interface GigabitEthernet1/0/1

#

security-zone name Trust

 import interface GigabitEthernet1/0/0

#

security-zone name Untrust

 import interface GigabitEthernet1/0/1

 import interface GigabitEthernet1/0/2

#

#3.安全策略

#

security-policy ip

 rule 0 name u-t

  action pass

  source-zone Trust

  destination-zone Untrust

 rule 1 name Local-any

  action pass

  source-zone Local

 rule 2 name t-L

  action pass

  source-zone Trust

  destination-zone Local

#

#4.创建链路组

#

nqa template icmp 10

 description ip 10.10.10.1

 out interface GigabitEthernet1/0/1

#

nqa template icmp 20

 description ip 20.20.20.1

 out interface GigabitEthernet1/0/2

#

loadbalance link-group lg

transparent enable

#

#5.配置链路

loadbalance link link1

 router ip 10.10.10.1

 link-group lg

 probe 10

#

loadbalance link link2

 router ip 20.20.20.1

 link-group lg

 probe 20

#

#6.配置虚服务器

#

virtual-server vs type link-ip

 virtual ip address 0.0.0.0 0

 default link-group lg

 service enable

#
