(Optional) Configuring Refined IPv6 Route Advertisement

Refined IPv6 route advertisement can classify routes and advertise them to different networks.

Context

IPv6 network segment routes and address pool routes are classified based on tags and imported using routing policies. This process allows various routes to be advertised to specific networks. IPv6 network segment routes are generated based on Delegated-IPv6-Prefix attributes that are delivered by a RADIUS server.

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 ipv6 unr { delegated-ipv6-prefix-tag tag-value | delegated-pool-tag tag-value | framed-ipv6-address-tag tag-value | framed-ipv6-prefix-tag tag-value | framed-ipv6-route-tag tag-value | local-pool-tag tag-value | remote-pool-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 ipv6 pool (system view)
  The IPv6 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 OSPFv3 or BGP+ to import different routes. For details, see "dRouting Policy Configuration."
