(Optional) Configuring Refined IPv4 Route Advertisement

Refined IPv4 route advertisement can classify routes and advertise them to different networks.

Context

User routes include routes generated by an address pool, and routes generated based on either the Framed-Route attribute or IP-Netmask attribute delivered by the RADIUS server. Management users can advertise routes to the management network while users accessing the Internet can advertise routes to the Internet. Routes are classified based on tags and imported using routing policies. This process allows various routes to be advertised to specific networks.

Procedure

Configure a route tag for a specified type of address pool, such as local or remote address pools.
1. Run system-view
  The system view is displayed.
2. Run ip unr { framed-route-tag tag-value | framed-ip-netmask-tag tag-value | framed-ip-address-tag tag-value } ^*
  A route tag is configured.
3. Run commit
  The configuration is committed.
Configure a route tag for a single address pool.
1. Run system-view
  The system view is displayed.
2. Run ip pool (system view)
  The IP address pool view is displayed.
3. Run unr tag tag-value
  A route tag is configured.
4. Run commit
  The configuration is committed.

Follow-up Procedure

Create a routing policy, specify a route tag to classify routes, and use OSPF or BGP to import various routes. For details, see "Routing Policy Configuration."
