Chapter 88: Tunnel administrative groups
Overview
Purpose
The NFM-P supports SDP admin groups—or steering parameters—on all NEs and on all service tunnel types. However, steering parameters are NFM-P objects that are not deployed to NEs. The 7750 SR supports the use of SDP admin groups, which enable services to use PW templates for automatic inclusion or exclusion of specific SDPs.
See the 7750 SR documentation for information about SDP admin groups
In the context of NFM-P management, steering parameters are called tunnel administrative groups. A tunnel administrative group uses steering parameter and SDP admin group concepts.
Tunnel administrative groups use the NFM-P policy distribution model. You can create a global tunnel administrative group and distribute it locally to NEs. Consider the following when you create a tunnel administrative group:
-
an SDP can be added to more than one tunnel administrative group
- tunnel administrative groups are supported on:
-
you cannot assign tunnel administrative groups to an SDP using an LDP IPv6 FEC
SDPs that share a specific characteristic or attribute can be made members of the same tunnel administrative group. When you create a service PW template, you can include and exclude one or more tunnel administrative groups. When a service is bound to the template, the SDP selection rules enforce the specified tunnel administrative group inclusion and exclusion constraints. Tunnel administrative groups allow you to control the SDP, or set of SDPs, that are selected while spokes are established among service sites using PW templates in BGP-AD, BGP-VPLS, or MS-PW applications. Tunnel administrative groups can be assigned to services that use the PW template policy, such as BGP-AD VPLS services, BGP-VPLS services, and Epipe spoke SDP FEC services. See Chapter 83, Service PW template policies for more information about PW template policies.
In addition, you can apply tunnel administrative groups to tunnel selection profiles. Tunnel selection profiles assign transport tunnels for a service when the service has been configured for automatic SDP binding creation. When a tunnel selection profile is used within a service to create SDP bindings, any tunnels that include the tunnel administrative group in that profile become eligible for consideration in the tunnel selection process. See Chapter 33, Service tunnels for more information about tunnel selection profiles.
