ipv6-pool(Remote backup profile view)

Usage Scenario

In a dual device hot backup scenario, an exclusively used address pool is bound to an RBP backup group. To control network-to-user traffic, user packets must be properly forwarded on the network so that the device through which users go online forwards the traffic to the users properly. An exclusively used address pool allows a network segment route to be advertised to the network using an IGP. In this mode, the master and backup devices cannot advertise the same network segment route at the same time. Advertising the same network segment route will cause load balancing on the network and network-to-user traffic to be forwarded incorrectly.

To resolve this problem, run the ipv6-pool command to achieve the RBP controls the advertisement and withdrawal of network segment routes of the address pool. When the RBP is in the master state, the RBP advertises network segment routes of the address pool to the network side. When the RBP is not in the master state, the RBP withdraws network segment routes of the address pool. In this way, correct routes can be learned on the network side to guide the proper forwarding of network-to-user traffic.

Prerequisites

Ensure that the following operations have been performed:

• An IPv6 address pool (the destination address pool) has been created using the ipv6 pool<pool-name>bas local command in the system view. An IPv6 prefix pool has been bound to the IPv6 address pool using the prefix<prefix-address / prefix-length>command in the IPv6 address pool view.
• Prefixes have been configured in the IPv6 prefix pool using the prefix<prefix-name> command in the IPv6 prefix pool view.

Precautions

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