一、静态路由简介
静态路由是一种特殊的路由，由管理员手工配置。当网络结构比较简单时，只需配置静态路由就可以使网络正常工作。
静态路由不能自动适应网络拓扑结构的变化。当网络发生故障或者拓扑发生变化后，必须由网络管理员手工修改配置。
二、静态路由配置
| 操作 |
命令 |
说明 |
| 进入系统视图 |
system-view |
- |
| （可选）创建静态路由配置组，并进入静态路由配置组视图 |
ip route-static-group group-name |
缺省情况下，未配置静态路由配置组 |
| （可选）在静态路由配置组中增加前缀 |
prefix dest-address { mask-length | mask } |
缺省情况下，静态路由配置组中未配置前缀 |
| （可选）退回系统视图 |
quit |
- |
| 配置静态路由 |
ip route-static { dest-address { mask-length | mask } | group group-name } { interface-type interface-number [ next-hop-address ] | next-hop-address [ recursive-lookup host-route ] [ track track-entry-number ] | vpn-instance d-vpn-instance-name next-hop-address [ recursive-lookup host-route ] [ track track-entry-number ] } [ permanent ] [ preference preference ] [ tag tag-value ] [ description text ] |
二者选其一 缺省情况下，未配置静态路由 |
| ip route-static vpn-instance s-vpn-instance-name { dest-address { mask-length | mask } | group group-name } { interface-type interface-number [ next-hop-address ] | next-hop-address [ recursive-lookup host-route ] [ public ] [ track track-entry-number ] | vpn-instance d-vpn-instance-name next-hop-address [ recursive-lookup host-route ] [ track track-entry-number ] } [ permanent ] [ preference preference ] [ tag tag-value ] [ description text ] |
||
| （可选）配置静态路由向下一跳定时发送ARP request |
ip route-static arp-request interval interval |
缺省情况下，静态路由不发送ARP request |
| （可选）配置静态路由的缺省优先级 |
ip route-static default-preference default-preference |
缺省情况下，静态路由的缺省优先级为60 |
| （可选）删除所有静态路由 |
delete [ vpn-instance vpn-instance-name ] static-routes all |
- |
三、静态路由显示
| 操作 |
命令 |
| 查看静态路由表信息（本命令的详细情况请参见“三层技术-IP路由命令参考”中的“IP路由基础”） |
display ip routing-table protocol static [ inactive | verbose ] |
| 显示静态路由下一跳信息 |
display route-static nib [ nib-id ] [ verbose ] |
| 显示静态路由表信息 |
display route-static routing-table [ vpn-instance vpn-instance-name ] [ ip-address { mask-length | mask } ] |
