What are association groups?

Association groups

Association groups use a specific criteria to identify LSPs with some shared attribute and organize those LSPs into a group. In the NSP implementation, NSP can group LSPs with one of two common attributes.

PCE-initiated LSPs can be assigned to an association group of the subtype 'Policy' during creation (see How do I create PCE-initiated LSPs?). PCC-initiated LSPs can also be discovered with 'Policy' association groups already configured on the PCC. A 'Policy' association group is used to tag LSPs with traffic engineering criteria and policy behavior. The NSP will interpret this discovered policy object by retrieving an NSP-created path profile object definition that matches the same ID. The path profile traffic engineering criteria and behavior will be invoked on the LSP, however, the diversity and bi-directionality configurations specified inside of the path profile object will be ignored.

PCC-initiated LSPs can also be discovered with association groups of the subtype 'Disjoint' configured. This is used to group LSPs that must remain diverse from one another during path calculation based on shared constraints.

All existing association groups and their members can be viewed from the Path Control, Policies view.
