(sr-mpls | srv6);
}Hierarchy Level
[edit protocols source-packet-routing]
Description
Enable preserve-nexthop hierarchy support for source packet routing. When you
enable preserve-nexthop-hierarchy, SRv6 TE transport is
populated correctly so that service resolution is performed properly. The
preserve-nexthop-hierarchy statement at the
[edit protocols source-packet-routing] hierarchy
level is a prerequisite for configuring SR-TE SRv6 tunnels. However, if you
enable the global configuration statement set routing-options
resolution preserve-nexthop-hierarchy, then
preserve-nexthop-hierarchy statement at the
[edit protocols source-packet-routing] is not
mandatory. Additionally, you have an option to enable the
preserve-nexthop-hierarchy only for a certain data
plane for transports populated by SR-TE. The following options when enabled
disable the preserve-nexthop-hierarchy for that data
plane.
Options
| sr-mpls | Disable preserve-nexthop-hierarchy for sr-mpls. |
| srv6 |
Disable preserve-nexthop-hierarchy for srv6. |
