Configuring MIP for Bridge Domains of a Virtual Switch
The default maintenance domain configuration allows MIP configuration for bridge
domains for a default virtual switch or a user-defined virtual switch. You can use the
virtual-switch and bridge-domain statements to specify which MIPs to enable for a
user-defined virtual switch.
A bridge domain must be specified by name only if it is configured by including the vlan-id
id statement under the virtual-switch statement.
If a bridge domain is configured with a range of VLAN IDs, then the VLAN IDs must be
explicitly listed after the bridge domain name.
To configure a bridge domain under a user-defined virtual switch, include the virtual-switch
name statement at the [edit protocols oam ethernet connectivity-fault-management
maintenance-domain domain-name default-x] hierarchy level.
[edit protocols oam ethernet connectivity-fault-management maintenance-domain
domain-name default-x]
virtual-switch name {
bridge-domain {
name-1;
name-2 {
vlan-id [vlan-ids ];
}
}
}
Configuring the Maintenance Domain Bridge Domain
The VLAN corresponds to the bridge domain.
To configure the bridge domain for the default virtual switch, include the bridge-domain
statement at the [edit protocols oam ethernet connectivity-fault-management
maintenance-domain maintenance-domain-name] hierarchy level.
Configuring the Maintenance Domain Instance
To configure the maintenance domain instance for a VPLS routing instance, include the
instance statement at the [edit protocols oam ethernet connectivity-fault-management
maintenance-domain] hierarchy level.
Configuring the Maintenance Domain MIP Half Function
186
MIP Half Function (MHF) divides MIP functionality into two unidirectional segments,
improves visibility with minimal configuration, and improves network coverage by
increasing the number of points that can be monitored. MHF extends monitoring capability
by responding to loopback and linktrace messages to help isolate faults.
Whenever a MIP is configured and a bridge domain is mapped to multiple maintenance
domains or maintenance associations, it is essential that the MIP half function value for
