lsp-trigger segment-routing-interworking best-effort host

Function

The lsp-trigger segment-routing-interworking best-effort host command enables a device to stitch SR LSPs to the proxy egress LSPs and transit LSPs that are established over non-local host routes with 32-bit mask.

The undo lsp-trigger segment-routing-interworking best-effort host command disables this function.

By default, this function is disabled.

Usage Guidelines

Usage Scenario

When an SR network needs to interwork with an LDP network, LDP and SR LSPs must be stitched so that LDP LSP traffic can be switched to SR LSPs for forwarding. After the lsp-trigger segment-routing-interworking best-effort host command is run, all non-local 32-bit host routes are stitched with SR LSPs on behalf of egress LSPs and transit LSPs. If the stitching succeeds, traffic can be switched to the SR LSPs for forwarding.

Prerequisites

MPLS LDP has been enabled globally using the mpls command in the system view.
