To solve the problem of bandwidth waste and to implement traffic load balancing and link
backup, multi-instance can be deployed in the SEP network and mappings between protected
instances and user VLANs need to be set, as shown in Figure 10-10. Data traffic of different
VLANs can be transmitted along different paths.
NOTE
Currently, SEP multi-instance allows two SEP segments to be configured on a physical ring network.
Pre-configuration Tasks
Before configuring SEP multi-instance, complete the following tasks:
l Configuring Basic SEP Functions
l Specifying an Interface to Block
Data Preparation
To configure SEP multi-instance, you need the following data.
