Configuring MIP Generation Rules
As functional entities in a service instance, MIPs deal with LBM and LTM messages.
MIPs are generated on each port according to some rules. You can choose appropriate MIP generation
rules based on your network design.
Follow these steps to configure the rules for generating MIPs:

follow the rules in
Table 1-1 to create or not create MIPs (within a single VLAN):
