Static Routing Configuration Commands
ip route-static default-preference
The term “router” in this document refers to a router in a generic sense or a Layer 3 switch.
Static Routing Configuration Commands
delete static-routes all
Syntax
delete [ vpn-instance vpn-instance-name ] static-routes all
View
System view
Default Level
2: System level
Parameters
vpn-instance-name: Name of a VPN instance, a string of 1 to 31 case-sensitive characters.
Description
Use the delete static-routes all command to delete all static routes.
When you use this command to delete static routes, the system will prompt you to confirm the operation before deleting all the static routes.
Related commands: display ip routing-table, ip route-static.
Examples
# Delete all static routes on the router.
<Sysname> system-view
[Sysname] delete static-routes all
This will erase all ipv4 static routes and their configurations, you must reconf
igure all static routes

ip route-static
Syntax
ip route-static dest-address { mask | mask-length } { next-hop-address [ track track-entry-number ] | interface-type interface-number next-hop-address | vpn-instance d-vpn-instance-name next-hop-address [ track track-entry-number ] } [ preference preference-value ] [ tag tag-value ] [ description description-text ]
undo ip route-static dest-address { mask | mask-length } [ next-hop-address | interface-type interface-number [ next-hop-address ] | vpn-instance d-vpn-instance-name next-hop-address ] [ preference preference-value ]
ip route-static vpn-instance s-vpn-instance-name&<1-6> dest-address { mask | mask-length } { next-hop-address [ track track-entry-number ] [ public ] | interface-type interface-number next-hop-address | vpn-instance d-vpn-instance-name next-hop-address [ track track-entry-number ] } [ preference preference-value ] [ tag tag-value ] [ description description-text ]

Parameters
vpn-instance s-vpn-instance-name&<1-6>: Specifies the VPN instance name, which is a string of 1 to 31 case-sensitive characters. &<1-6> indicates the argument before it can be entered up to 6 times. Each VPN instance has its own routing table, and the configured static route is installed in the routing tables of the specified VPN instances.
dest-address: Destination IP address of the static route, in dotted decimal notation.
mask: Mast of the IP address, in dotted decimal notation.
mask-length: Mask length, in the range 0 to 32.
next-hop-address: IP address of the next hop, in dotted decimal notation.
interface-type interface-number: Specifies the output interface by its type and number.
vpn-instance d-vpn-instance-name: Name of the destination VPN instance, case-sensitive. If a destination VPN instance name is specified, the router will search the output interface in the destination VPN instance based on the configured next-hop-address.
next-hop-address public: Indicates that the specified next-hop-address is a public network address, rather than a VPN instance address.
preference preference-value : Specifies the preference of the static route, which is in the range of 1 to 255 and defaults to 60.
tag tag-value: Sets a tag value for the static route from 1 to 4294967295. The default is 0. Tags of routes are used in routing policies to control routing.
description description-text: Configures a description for the static route, which consists of 1 to 60 characters, including special characters like space, but excluding ?.
track track-entry-number: Associates the static route with a track entry. Use the track-entry-number argument to specify a track entry number, in the range 1 to 1024.
Description
Use the ip route-static command to configure a unicast static route.
Use the undo ip route-static command to delete a unicast static route.
When configuring a unicast static route, note that:
1) If the destination IP address and the mask are both 0.0.0.0, the configured route is a default route. If routing table searching fails, the router will use the default route for packet forwarding.
2) Different route management policies can be implemented for different route preference configurations. For example, specifying the same preference for different routes to the same destination address enables load sharing, while specifying different preferences for these routes enables route backup.
Related commands: display ip routing-table, ip route-static default-preference.
l The static route does not take effect if you specify its next hop address first and then configure the address as the IP address of a local interface.
l The next hop address must not be the IP address of the local interface; otherwise, the route configuration will not take effect.
l For a NULL0 interface, if the output interface has already been configured, there is no need to configure the next hop address.
l To configure track monitoring for an existing static route, simply associate the static route with a track entry. For a non-existent static route, configure it and associate it with a Track entry.
l If the track module uses NQA to detect the reachability of the private network static route's nexthop, the VPN instance number of the static route's nexthop must be identical to that configured in the NQA test group.
l If a static route needs route recursion, the associated track entry must monitor the nexthop of the recursive route instead of that of the static route; otherwise, a valid route may be mistakenly considered invalid.
Examples
# Configure a static route, whose destination address is 1.1.1.1/24, next hop address is 2.2.2.2, tag value is 45, and description information is for internet & intranet.
<Sysname> system-view
[Sysname] ip route-static 1.1.1.1 24 2.2.2.2 tag 45 description for internet & intranet
# Configure a static route for a VPN instance named vpn1: the destination address is 1.1.1.1/16 and the next hop address is 1.1.1.2, which is the address of this VPN instance.
<Sysname> system-view
[Sysname] ip route-static vpn-instance vpn1 1.1.1.1 16 vpn-instance vpn1 1.1.1.2
ip route-static default-preference
Syntax
ip route-static default-preference default-preference-value
undo ip route-static default-preference
View
System view
Default Level
2: System level
Parameters
default-preference-value: Default preference for static routes, which is in the range of 1 to 255.
Description
Use the ip route-static default-preference command to configure the default preference for static routes.
Use the undo ip route-static default-preference command to restore the default.
By default, the default preference of static routes is 60.
Note that:
l If no preference is specified when configuring a static route, the default preference is used.
l When the default preference is re-configured, it applies to newly added static routes only.
Related commands: display ip routing-table, ip route-static.
Examples
# Set the default preference of static routes to 120.
