Abstract: The present disclosure provides a method and apparatus for DBNG-UP redundancy. The method includes: configuring a redundancy group instance on a DBNG-CP, wherein redundancy group members managed by the DBNG-CP at least include a first DBNG-UP and a second DBNG-UP; and performing, by the DBNG-CP, UP redundancy capability negotiation with the first DBNG-UP and the second DBNG-UP respectively, to complete active/standby election between the first DBNG-UP and the second DBNG-UP. In the present disclosure, a DBNG-CP performs UP redundancy capability negotiation with DBNG-UPs managed by the DBNG-CP, so as to complete active/standby election of the DBNG-UP, thereby solving the problem of UP redundancy capability negotiation, and increasing the flexibility of DBNG-UP redundancy protection.
