ip unr

Function

The ip unr command configures route tags for IPv4 users.

The undo ip unr command restores the default route tag.

The default tag is set to 0, which means that user routes are not classified.

This command is supported only on the NetEngine 8000 F1A.

Format

ip unr { local-pool-tag tag-value | remote-pool-tag tag-value | framed-route-tag tag-value | framed-ip-netmask-tag tag-value | framed-ip-address-tag tag-value | dynamic-pool-tag tag-value } ^*

undo ip unr { local-pool-tag | remote-pool-tag | framed-route-tag | framed-ip-netmask-tag | framed-ip-address-tag | dynamic-pool-tag } ^*

Parameters

Parameter	Description	Value
local-pool-tag tag-value	Specifies the route tag of the network segment generated by an IPv4 local address pool.	The value is an integer ranging from 0 to 4294967295.
remote-pool-tag tag-value	Specifies the route tag of the network segment generated by an IPv4 remote address pool.	The value is an integer ranging from 0 to 4294967295.
framed-route-tag tag-value	Specifies the route tag of the network segment generated based on the Framed-Route attribute delivered by the RADIUS server.	The value is an integer ranging from 0 to 4294967295.
framed-ip-netmask-tag tag-value	Specifies the route tag of the network segment generated based on the IP-Netmask attribute delivered by the RADIUS server.	The value is an integer ranging from 0 to 4294967295.
framed-ip-address-tag tag-value	Specifies the route tag of the host route generated based on the IPv4 address delivered by the RADIUS server.	The value is an integer ranging from 0 to 4294967295.

Usage Guidelines

Usage Scenario

Configuring tags and using routing policies allows various user routes to be advised to specific networks.

Configuration Impact

The ip unr command takes effect globally, and routes are classified based on tags. Tag values are specified in routing policies to advertise routes to specific networks.

This command takes effect on routes of new access users, routes of a new IPv4 address pool, and routes of a modified IPv4 address pool. However, this command does not take effect on UNR routes that have been generated on the device.

Route tags of different types can be configured at the same time. If a type of route has multiple tags configured, the latest configuration takes effect.

Follow-up Procedure

Specify a behavior to process a route that matches a specified tag value in a routing policy. Use a routing protocol to import the routes based on the specified routing policy.

Precautions

In VS mode, this command is supported only by the admin VS.

Example

# Generate a tag value by means of configuring the UNR route globally.
