Description
Define router clusters or groups, similar to the sequence of real-hop constraints (strict or loose), as a sequence of abstract hops for setting up a label-switched path (LSP).
An abstract hop is a logical combination of the existing traffic engineering constraints, such as administrative groups, extended administrative groups, and Shared Risk Link Groups (SRLGs), along with the ordering property of real hops. As a result, when a sequence of abstract hops is used in a path constraint, ordering is achieved among the groups of routers that meet a logical combination of link or node attributes called constituent attributes. A path can use a combination of real and abstract hops as constraints.
Options
| abstract-hop-name | Name of the abstract hop that is a logical combination of the existing traffic engineering constraints, such as administrative groups, extended administrative groups, and SRLGs, along with the ordering property of real hops. |
| constituent-list constituent-list-name | Name of the predefined constituent list to be included in defining the abstract hop. A constituent list enables you to define a set of constituent attributes that is identified with a user-defined name. |
| include-any-list | Satisfy any one of the attributes specified in the constituent list. |
| include-all-list | Satisfy all of the attributes specified in the constituent list. |
| exclude-all-list | Satisfy none of the attributes specified in the constituent list. |
| exclude-any-list | Fail to satisfy any one of the attributes specified in the constituent list. |
| operators | Specify the operation between constituent lists when more than one constituent list is included in the abstract hop definition. |
| AND | Satisfy all the constituent lists referenced in the abstract hop definition for the attached node to be a member of the abstract hop. |
| OR | Satisy at least one of the constituent lists referenced in the abstract hop definition for the attached node to be a member of the abstract hop. |
