Configuring static routing
Static routes are manually configured. If a network's topology is simple, you only need to configure static
routes for the network to work correctly.
Static routes cannot adapt to network topology changes. If a fault or a topological change occurs in the
network, the network administrator must modify the static routes manually.
Configuring a static route
Before you configure a static route, complete the following tasks:
• Configure the physical parameters for related interfaces.
• Configure the link-layer attributes for related interfaces.
• Configure the IP addresses for related interfaces.
Follow these guidelines when you configure a static route:
• The next hop address of a static route cannot be the IP address of a local interface. Otherwise, the
static route does not take effect.
• You can associate track entry with a static route to monitor the reachability of the next hops. For
more information about Track, see High Availability Configuration Guide.
To configure a static route:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure a static
route.
• Method 1:
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 ]
[ permanent ] [ description description-text ]
• Method 2:
ip route-static vpn-instance
s-vpn-instance-name&<1-6> dest-address
{ mask | mask-length } { next-hop-address
[ public ] [ 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 ]
[ permanent ] [ description description-text ]
Use either method.
By default, no static route is
configured.
3. Configure the
default preference
for static routes.
ip route-static default-preference
default-preference-value Optional.
60 by default.
