Description
Calculate post-convergence MPLS fast reroute (FRR)
backup next hops for the OSPF protocol using segment routing (SR). Junos
OS allows you to control the maximum number of equal-cost multipath
(ECMP) backup paths installed for a given destination. Junos OS also
allows you to control the maximum number of labels in the installed
backup paths. Configure the use-source-packet-routing statement
at [edit protocols ospf backup-spf-options] hierarchy level
to allow the backup paths to be available for inet.0 routing table
along with inet.3 routing table.
Options
| maximum-backup-paths | Set the maximum number of equal-cost post-convergence backup paths to be installed.
|
| maximum-labels | Set the maximum number of labels used to construct a post-convergence backup path. If the backup path for a particular prefix requires more labels than the configured maximum labels, then the backup path for that particular prefix is not installed. Note:
