The src-dt6 locator command sets or changes the Src.DT6 value of a sender PE on an MVPNv6 over BIERv6 network.
The undo src-dt6 locator command deletes the Src.DT6 value.
By default, no Src.DT6 value is configured.
| Parameter | Description | Value |
|---|---|---|
| locator-name |
Specifies the name of a SID node route section. |
The value is a string of 1 to 31 case-sensitive characters. When double quotation marks are used around the string, spaces are allowed in the string. |
| sid sid-val |
Specifies an SID. |
The value is a 32-digit hexadecimal number, in the format of X:X::X:X. |
| signal-format |
Specifies the SID signaling format. |
- |
| msid |
Indicates that the SID signaling format is MSID. |

Usage Scenario
In an MVPNv6 over BIERv6 network, an Src.DT6 address must be configured on the sender PE. The Src.DT6 address is an IPv6 address. After being configured, the Src.DT6 address is used as the source address of the IPv6 packet header, and receiver PEs use it to differentiate MVPN instances. By default, the Src.DT6 source address in the I-PMSI A-D, (*, G), or (*, *) S-PMSI A-D route sent by the ingress is carried in the BGP Prefix-SID attribute. If signal-format msid is configured, the Src.DT6 source address in the I-PMSI A-D, (*, G), or (*, *) S-PMSI A-D route sent by the ingress is carried in the MSID.
