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.
