Dynamic bypass configurations

The configurations steps for dynamic bypass LSPs are as follows:
  1. Enable the dynamic bypass on MPLS router mode.
  2. Optional step Set the global dynamic bypass configurable parameters.
  3. Optional step To enable a dynamic bypass on all the MPLS interfaces without going to each interface use the enable-all-interfaces command in the global mode. Otherwise, go to next step to enable a dynamic bypass on individual MPLS interfaces and customize the way the dynamic bypass get created for a protected interface. The user can also override the enable-all-interfaces commands effect on individual MPLS interfaces by configuring the dynamic bypass in those interfaces explicitly as in the next steps.
  4. Enable a dynamic bypass on one or more MPLS interfaces. This step is optional when using step 3.
  5. Optional step Set interface level dynamic bypass configurable parameters.

All modifications to the dynamic bypass interface or the router mode configuration parameters apply to the new creation of dynamic bypass LSPs.

Dynamic bypass parameter changes made at the interface level only apply to the existing dynamic bypass LSPs protecting this interface, when triggered by events such as the re-optimization timer expiry or user intervention.

The configurable parameters include, but are not limited to bandwidth, hop-limit, priority, cos, adaptiveness, and primary path. These apply to all dynamic bypass LSPs created to protect this interface.
