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:
To do... Use the command... Remarks
Enter system view system-view —
Configure the rules for
generating MIPs
cfd mip-rule { explicit |
default } service-instance
instance-id
Required
By default, neither the MIPs nor the
rules for generating MIPs are
configured.
MIPs are generated on each port automatically according to the rules specified in the cfd mip-rule
command. If a port has no MIP, the system will check the MAs in each MD (from low to high levels),
and follow the rules in
Table 6-1 to create or not create MIPs (within a single VLAN):
Table 6-1 Rules for generating MIP
MIP exists on low
level MA
The cfd mip-rule
command is
configured as
MEP exists on low
level MA
Create MIP or not
Yes — — No
No No
Explicit
Yes Yes
No
Default — Yes
Each of the following actions or cases can cause MIPs to be created or deleted after you have
configured the cfd mip-rule command:
z Enabling CFD (use the cfd enable command)
z Creating or deleting the MEPs on a port
z Changes occur to the VLAN attribute of a port
z The rule specified in the cfd mip-rule command changes
