3. Enable the multicast function and the PIM function on the entire network. Configure the
public network-based multicast between PEs and Ps and configure the VPN instance-based
multicast between PEs and CEs.
4. Configure the identical Share-Group address, MTI, and address pool range of Switch-MDT
for the same VPN instance on each PE.
5. Configure the MTI address of each PE as the IBGP peer interface address on the public
network, and enable PIM on the MTI.
Data Preparation
See Table 8-2 in "Networking Requirements."

Step 1 # Configure PE-A.
# Configure the ID of PE-A, enable IP multicast routing on the public network, configure the
ID of the MPLS LSR, and then enable LDP.

# Create a VPN-RED instance and enter the VPN instance view. Configure the VPN IPv4 prefix
and create ingress and egress routes of the instance. Enable IP multicast routing and configure
the Share-Group. Specify the MTI to be bound to the VPN instance and address pool range of
Switch-MDT.
