CS SSVM网络不通
HI：
KVM主机网络配置：
物理网卡：ifcfg-em1 ifcfg-em2 ifcfg-em3
桥接： ifcfg-cloudbr0 ifcfg-cloudbr1 ifcfg-cloudbr2
具体设置：
more ifcfg-em1
DEVICE=em1
ONBOOT=yes
BOOTPROTO=none
HOTPLUG=no
TYPE=Ethernet
BRIDGE=cloudbr0
more ifcfg-cloudbr0
DEVICE=cloudbr0
ONBOOT=yes
TYPE=Bridge
BOOTPROTO=none
DEEROUTE=yes
DELAY=5
STP=yes
IPADDR=10.10.50.1
NETMASK=255.255.255.0
GATEWAY=10.10.50.250
DNS1=172.20.1.250
more ifcfg-em2
DEVICE=em2
ONBOOT=yes
BOOTPROTO=none
HOTPLUG=no
TYPE=Ethernet
BRIDGE=cloudbr1
more ifcfg-cloudbr1
DEVICE=cloudbr1
ONBOOT=yes
TYPE=Bridge
BOOTPROTO=none
DELAY=5
STP=yes
IPADDR=10.10.60.1
NETMASK=255.255.255.0
KVM主机上ping 10.10.60.250
ping 10.10.60.250
PING 10.10.60.250 (10.10.60.250) 56(84) bytes of data.

SSVM的公网IP无发ping通：
公用 IP 地址10.10.60.210
登陆该SSVM,查看路由：
root@v-2-VM:~# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface

到默认网关不通：
root@v-2-VM:~# ping 10.10.60.250
PING 10.10.60.250 (10.10.60.250): 56 data bytes

这个网络应该怎么排查？？
