Default Route
To avoid too large a routing table, you can configure a default route.
When the destination address of a packet fails to match any entry in the routing table,
z
If there is default route in the routing table, the default route will be selected to forward the packet.
z
If there is no default route, the packet will be discarded and an ICMP Destination Unreachable or
Network Unreachable packet will be returned to the source.
A default route can be manually configured or generated by some dynamic routing protocols, such as
OSPF and RIP.
Static Route Configuration
Configuration Prerequisites
Before configuring a static route, perform the following tasks:
z
Configuring the physical parameters of related interfaces
z
Configuring IP addresses for related interfaces
Configuring a Static Route
Follow these steps to configure a static route:
To do... Use the command... Remarks
Enter system view system-view —
Configure a static
route
ip route-static ip-address { mask | mask-length }
{ interface-type interface-number | next-hop }
[ preference preference-value ] [ reject | blackhole ]
[ detect-group group number ] [ description text ]
Required
By default, the system can
obtain the route to the subnet
directly connected to the
router.
z
Use the ip route-static command to configure a default route by setting the destination IP address
and the mask to 0.0.0.0.
z
Avoid configuring the next hop address of a static route to the address of an interface on the local
device.
z
Different preferences can be configured to implement flexible route management policies.
