dmr-prefix (System view)
Function
The dmr-prefix command sets a default mapping rule (DMR) IPv6 prefix on a BR.
The undo dmr-prefix command deletes a DMR IPv6 prefix.
By default, no DMR IPv6 prefix is configured.

Usage Guidelines
Usage Scenario
To set a DMR IPv6 prefix on a BR, run the dmr-prefix command in the system view. The prefix is used to verify and encapsulate MAP packets.
Precautions
- A single IPv6 prefix can be set for each DMR.
- The IPv6 prefix address is mutually exclusive with an interface IP address, an address in a BRAS address pool.
