进行 lb route 配置
虚拟服务器必须配置固定的IP地址和端口以及协议
协议: ANY IP地址: 0.0.0.0 端口: 0
LLB的负载均衡虚拟服务器的名字建议命名为: lb_vsrv_isp_llb_all lb_vsrv_isp_llb_ct lb_vsrv_isp_llb_cu lb_vsrv_isp_llb_cmcc lb_vsrv_isp_llb_edu
LLB的虚拟服务的名字建议命名为: svc_isp_ct svc_isp_cu svc_isp_cmcc svc_isp_edu
虚拟服务器支持的负载算法和会话保持算法
支持的负载算法: DESTINATIONIPHASH LEASTBANDWIDTH LEASTPACKETS LRTM ROUNDROBIN SOURCEIPHASH SRCIPDESTIPHASH
支持的会话保持算法: SOURCEIP SRCIPDESTIP DESTIP

问题1: 添加服务器的IP地址，不能为D类和E类的IPv4地址。
D类地址 前四位为1110，注意是位
1、不分网络地址和主机地址。
2、地址范围：224.0.0.1 --- 239.255.255.254
E类地址 前五位为11110，注意是位
1、不分网络地址和主机地址
2、地址范围：240.0.0.1 --- 255.255.255.254

问题2: 添加路由项时，若网关与设备不在同一网段(简单理解即没有与之互通的SNIP)，则操作失败，提示【ERROR: The gateway is not directly reachable】
