A sending interface can be specified in the following cases:

■

For a point-to-point interface, when a sending interface is specified, it 
implicates that the next-hop address is also specified. In this case, the peer 
interface address connected with the interface is regarded as the next-hop 
address of the route. For example, in the case that SERIAL interface is 
encapsulated with PPP, the peer IP address can be obtained via PPP negotiation. 
It is unnecessary to specify the next-hop address but specifying the sending 
interface.

■

For an NBMA interface (such as an ATM interface), which supports 
point-to-multipoint, it is necessary to create reroute at link layer, namely the 
mapping from an IP address to a link layer address, besides configuring IP 
routes. To configure static route in this case, you should configure the next-hop 
IP address rather than specify the sending interface.

3 Precedence

The preference can be configured differently by flexibly applying route 
management policies.

4 Other parameters

The attributes reject and blackhole respectively indicate the unreachable route and 
the blackhole route.

Perform the following in the System View.

The meanings of parameters in the command are the same as those of the static 
route.

Perform the following in the System View.

This command can be used to delete all the static routes configured, including 
default routes.

Table 539   Configuring the default route

Configure the 
default route

ip route-static 0.0.0.0 { 0.0.0.0 | 0 } 
{interface-name | nexthop-address } [ preference value 
] [ reject | blackhole ]

ip route-static vpn-instance vpn-instance-name 
0.0.0.0 { 0.0.0.0 | 0 } {interface-name | 
nexthop-address } [ preference value ] [ reject | 
blackhole ]

Delete the 
default route

undo ip route-static 0.0.0.0 { 0.0.0.0 | 0 } 
{interface-name | nexthop-address} [ preference value 
] 

undo ip route-static vpn-instance vpn-instance-name 
0.0.0.0 { 0.0.0.0 | 0 } {interface-name | 
nexthop-address } [ preference value ] [ reject | 
blackhole ]
