Chapter 4 Managing a FlexUNI/EVC Ethernet Service Request
Setting the Service Request Details
Step 8 Check the Configure Bridge Domain check box to determine bridge domain characteristics.
The behavior of the Configure Bridge Domain option works in tandem with the choice you selected in
the MPLS Core Connectivity Type option in the FlexUNI/EVC policy, which in this case is pseudowire
core connectivity. There are two cases:
• With FlexUNI:
– If Configure With Bridge Domain is checked, the policy will configure pseudowires under
SVIs associated to the bridge domain.
– If Configure With Bridge Domain is unchecked, the policy will configure pseudowires
directly under the service instance. This will conserve the global VLAN.
• Without FlexUNI:
– If Configure With Bridge Domain is checked, the policy will configure pseudowires under
SVIs.
– If Configure With Bridge Domain is unchecked, the policy will configure pseudowires
directly under subinterfaces.
Pseudowires can be configured either directly under service instance of the corresponding
FlexUNI-capable interface or under SVIs associated to the bridge domain.
Step 9 Check the Use Split Horizon check box to enable split horizon with bridge domain.
Usage notes:
• The Use Split Horizon attribute is disabled by default.
• The Use Split Horizon attribute can be used only when the Configure Bridge Domain check box is
checked (enabled).
• When Use Split Horizon is enabled, the bridge domain command in the CLI will be generated with
split horizon. When it is disabled, the bridge domain command will be generated without split
horizon.
Step 10 Click the “Click here” link of the Description attribute to enter a description label for the service
request.
This is useful for searching the ISC database for the particular service request.
A dialogue appears in which you can enter a description.
Step 11 To set up direct connect links, see the section Setting Direct Connect Links, page 4-10 .
Step 12 To set up links with L2 access nodes, see the section Setting Links with L2 Access Nodes, page 4-20 .
VPLS Core Connectivity
If the MPLS Core Connectivity Type for the FlexUNI/EVC Ethernet policy is VPLS, the EVC Service
Request Editor window shown
Figure 4-2 appears.
