Description

The MPLS-forwarding type routing-instance can be used for segregating Inter-AS BGP neighbors that require MPLS spoof-protection to ensure the packets remain distinct from other peers.

Setting a forwarding context on a neighbor interface can be useful, for example, when configuring a common AS boundary router so that it only accepts MPLS packets from a peer AS boundary router whose labels were explicitly advertised to the common AS boundary router.

Use this statement in conjunction with mpls-forwarding to protect against label spoofing across AS boundary routers in the context of Inter-AS VPN Option B for AS boundary routers. Option B peers are reachable thru local interfaces that are configured as part of the MPLS forwarding type routing instance.

If forwarding-context is not set for a VPN BGP peer both the routing instance and forwarding context are provided by the master routing instance. The master instance is the Junos default, global routing-instance, that contains the protocols bgp configuration.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 16.1.
