CAC can take into account LSPs that have been configured with an MPLS path protection feature, such as secondary paths, fast reroute, or node and link protection. CAC can consider the bandwidth available on these auxiliary links and can accept the backup connection as valid if the main connection fails. However, there are limitations on how the path protection feature must be configured to prevent CAC from taking down the Layer 2 circuit when the LSP it is using is switched to a backup route.
For more information on MPLS path protection features, see the JUNOS MPLS Applications Configuration Guide.
The sections that follow discuss the path protection features that can be used in conjunction with CAC and how they must be configured:
