, PIM-SM is enabled in the network and all the PE devices support VPN instance
A. The process of establishing a share-MDT is as follows:
1) The public instance on PE 1 initiates a join to the public network RP, with the share-group address
as the multicast group address in the join message, and a (*, 239.1.1.1) state entry is created on
each device along the path in the public network. At the same time, PE 2 and PE 3 respectively
initiate a similar join process. Finally, an RPT is established in the MD, with the public network RP
as the root and PE 1, PE 2 and PE 3 as leaves.
2) The public instance on PE 1 registers the multicast source with the public network RP, with the
BGP interface address as the multicast source address and the share-group address as the
multicast group address in the register message, and a (11.1.1.1, 239.1.1.1) state entry is created
on each device along the path in the public network. At the same time, PE 2 and PE 3 respectively
initiate a similar register process. Finally, three SPTs between the PE devices and the RP are
established in the MD.
In the PIM-SM network, the RPT, namely the (*, 239.1.1.1) tree, and the three independent SPTs
constitute a share-MDT.
