By running multiple instances on each PE device, you enable the PE device to work for multiple VPNs. 

You need to configure the same share-group address for the same VPN instance on different PE 

devices. With a share-group and an MTI number configured, the system automatically creates an MTI, 

binds the share-group address to the MTI and binds the MTI to the current VPN instance.  

Follow these steps to configure a share-group and an MTI binding: 

Enter system view 

— 

Enter VPN instance view 

ip vpn-instance 
vpn-instance-name 

— 

Configure a share-group 
address and an MTI binding 

multicast-domain 
share-group group-address 
binding mtunnel 
mtunnel-number 

Required 

No share-group address or MTI 
binding is configured.
