Note
Local revertiveness is not supported in this release.When failover happens, traffic continues to flow in backup. When global revertiveness for FRR is configured, a new LSP is created from the ingress after the ingress learns about the failover. The new LSP is protected with a backup LSP, if possible. When the primary LSP fails for the second time, it may still be protected when there is a backup path available.
When secondary path is configured along with global revertive configuration, then when new instance of global revertive is triggered, the secondary path is also triggered. After "n" number of retries configured by user for establishing new instance for global revertiveness, traffic switches to the secondary path. The retry limit is configured in mpls policy mode. When the retry limit is not configured, then new instance establishment is tried infinite times.
