The embedded-rp command enables the embedded RP function.
The undo embedded-rp command disables the embedded RP function.
By default, the embedded RP function is enabled.
| Parameter | Description | Value |
|---|---|---|
| basic-acl6-number | Specifies the number of the basic ACL. | The value is an integer that ranges from 2000 to 2999. |
Usage Scenario
The embedded RP function is enabled by default after PIM-SM (IPv6) is enabled. This function enables the switch to obtain the RP address from the IPv6 multicast address of a received multicast packet, so that the switch does not need to know the RP information beforehand.
By default, the switch can parse group addresses in the range of FF7x::/12. The value of x can be 0 or any integer in the range of 3 to F. When the switch receives a multicast packet with an IPv6 group address in this range, the switch can obtain the RP address from the IPv6 group address. This RP will replace the static RP or dynamically elected RP. If you do not want the switch to use RP information obtained from IPv6 multicast addresses of multicast packets, run the undo embedded-rp command to disable the embedded RP function.
Prerequisites
IPv6 multicast routing has been enabled globally using the multicast ipv6 routing-enable command in the system view.
Precautions
If an IPv6 ACL is specified in the command, the final group address range for embedded RP is the intersection of the group address range specified by the IPv6 ACL and the default group address range. All the devices in the PIM (IPv6) domain must be configured with the same group address range.
For the IPv6 numbered ACL, in the ACL6 view, you can set the source address range of multicast groups that is enabled with the embedded RP by specifying the source parameter in the rule command.
For the IPv6 Named ACL, in the ACL6 view, when the rule command is used to configure a filtering rule, the filtering rule is effective only with the address range of multicast groups that is specified by the destination parameter and with the time period that is specified by the time-range parameter.
This command is cyclical in nature. That is, the latest command overwrites the previous one, and takes effect.
