How Do I Configure Multiple Static RPs on a Multicast Network?

How Do I Configure Multiple Static RPs on a Multicast Network?

You can run either of the following commands to configure static RPs and specify ACLs in the commands to define different group address ranges that the static RPs serve.
  • On an IPv4 network: run static-rp rp-address [ basic-acl-number | acl-name acl-name ] [ preferred ] [ bidir ]. (The bidir keyword is supported in V100R002C00 and later versions.)

  • On an IPv6 network: run static-rp rp-address [ basic-acl6-number | acl6-name acl6-name ] [ preferred ] [ bidir ]. (The bidir keyword is supported in V100R003C00 and later versions.)

If you do not specify an ACL or specify an ACL with no rules configured in the preceding commands, only one static RP can be configured, and the static RP serves all the multicast groups. If you specify an ACL with rules configured, the configured static RP serves only the multicast groups that match the ACL.

If both static and dynamic RPs are configured, which type of RP takes effect depends on the preferred keyword in the preceding commands. If the preferred keyword is not specified, the dynamic RP takes precedence over the static RP. If this keyword is specified, the static RP takes precedence over the dynamic RP.

If the bidir keyword is not specified, the configured static RP serves only the Protocol Independent Multicast Sparse Mode (PIM-SM) network. If this keyword is specified, the configured static RP serves only the Bidirectional PIM (Bidir-PIM) network.

To enable static RPs to function normally, perform the same static-rp configuration on all the devices in a PIM domain.

# On an IPv4 PIM-SM network, specify different static RPs for group addresses in different ranges and ensure that the static RPs are preferred.
