Description
Configure the installation of backup-paths that follow the post-convergence paths corresponding to the failure of this interface.
Options
| fate-sharing-protection | Enable fate-sharing protection. A list of fate-sharing groups are configured on each point of local repair (PLR) with the links in each fate-sharing group identified by their respective IP addresses. The PLR associates a cost with each fate-sharing group. The fate-sharing-aware post-convergence path is computed by assuming that the cost of each link in the same fate-sharing group as the failed link has increased the cost associated with that group. |
||||
| node-protection | Enable node protection mode for topology-independent loop-free alternate (TI-LFA) routes for OSPF.
