Configuring Anycast RP

Restrictions and guidelines

To prevent the other Anycast RP member devices from discarding the BSM sent by the BSR, make sure the Anycast RP address is different from the BSR address.

As a best practice to ensure network performance, configure a maximum of 16 Anycast RP members for an Anycast RP set.

As a best practice, configure the IPv6 address of a loopback interface as the RP member address.

If you configure IPv6 addresses of multiple interfaces on the same device as RP member addresses, the lowest IPv6 address takes effect. The rest of the interface addresses become backup RP member addresses.

You must add the device where the Anycast RP resides as an RP member to the Anycast RP set.

Prerequisites

You must configure a static RPs or C-RPs in the IPv6 PIM-SM domain before you configure the Anycast RP. Use the address of the static RP or the dynamically elected RP as the Anycast RP address.

Procedure

  1. Enter system view.

    system-view

  2. Enter IPv6 PIM view.

    ipv6 pim [ vpn-instance vpn-instance-name ]

  3. Configure Anycast RP.

    anycast-rp ipv6-anycast-rp-address ipv6-member-address

    You can repeat this command to add multiple RP member addresses to an Anycast RP set.
