The src-dt4 locator command sets or changes the Src.DT4 value of a sender PE on an MVPNv4 over BIERv6 network.
The undo src-dt4 locator command deletes the Src.DT4 value.
By default, no Src.DT4 value is configured.
| Parameter | Description | Value |
|---|---|---|
| locator-name |
Specifies the name of a node route segment. |
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 a SID. |
The value is a 32-digit hexadecimal number, in the format of X:X::X:X. |
| signal-format |
Specifies a SID signaling format. |
- |
| msid |
Sets the SID signaling format to MSID. |
- |
| locator |
Specifies a SRv6 locator. |

Usage Scenario
In an MVPNv4 over BIERv6 network, an Src.DT4 address must be configured on the sender PE. The Src.DT4 address is an IPv6 address. After being configured, the Src.DT4 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.DT4 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.DT4 source address in the I-PMSI A-D, (*, G), or (*, *) S-PMSI A-D route sent by the ingress is carried in the MSID.
