Figure 64 Source-side PE configuration
As shown in Figure 64, configure VPN instance A, create VPN instance B, and specify the share-group
on PE 1.
After the configuration, a share-MDT is established for VPN instance A and VPN instance B respectively
on the public network. After receiving multicast packets from Source 1, PE 1 duplicates and encapsulates
them, and forwards them to PE 2 and PE 3 along the share-MDTs. PE 2 and PE 3 de-encapsulate and
forward them to Receiver 1 and Receiver 2, respectively.
Receiver-side PE configuration
To implement multicast across VPNs, this configuration covers creating VPN instance that the multicast
source belongs to on the receiver-side PE, and configuring a share-group for the VPN instance.
