Design, configure, audit, and troubleshoot Juniper SRX MPLS L3VPN in flow mode. Use when handling Junos 24.2R1+ family mpls with inet or inet6 flow, secure PE or CPE, VRFs, LDP, MP-BGP, l3vpn vrf-group policy, VRF-to-zone mapping, VRF-aware NAT or AppID, PowerMode or RFP, MTU, labels, or policy matching.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

## Overview

Junos 24.2R1 introduced a cleaner SRX forwarding model for MPLS security use cases: keep `family mpls` in packet mode while processing `family inet` and `family inet6` in SRX flow mode. That lets an SRX act as an MPLS L3VPN PE/CPE and still apply stateful firewall, NAT, AppID, IPS/IDP, and other flow services to customer IPv4/IPv6 traffic.

The operational pattern is:

How to install

The exact contents, by fingerprint
mdr add mechubsec/fwskillsshare/srx-mpls-in-flow@sha256:b5c1f2b26aa2ea7a

The line at the top of this page pins the label v1.0.5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
