Usage Guidelines

Usage Scenario

In the VPN instance that the source PE is bound to, if the Switch-Group-Pool cannot provide enough addresses for VPN multicast data packets whose transmission path needs to be switched to the Switch-MDT, the multicast group addresses can be reused. To record information about reusing Switch-Group, enable the output of log information about reusing Switch-Group addresses.

Prerequisites

A Share-Group has been configured using the multicast-domain share-group binding command.

# Enable the output of log information about reusing Switch-Group addresses in VPN mytest.
