Pseudowire in VRF with Global LDP

Keith McElroy

I have a router with a VRF SVI that I need bound to another site with a pseudowire. The SVI is in a VRF, the LDP interface with all the bindings is in the global table. Is there a way to bleed it over to allow the VRF interface into the global LDP so it will peer? Closest thing I found was MPLS LDP-VRF-Aware Static Labels, but that seems messy and might not work in this instance.

 

Local interface: Vl117 up, line protocol up, Eth VLAN 117 up
  Destination address: 172.30.10.22, VC ID: 5, VC status: down
    Output interface: none, imposed label stack {}
    Preferred path: not configured
    Default path: no route
    No adjacency
  Load Balance: none
  Flow Label: Disabled
  Create time: 00:39:48, last status change time: 00:39:48
  Signaling protocol: LDP, peer 172.30.10.22:0 up
    Targeted Hello: 172.30.10.111(LDP Id) -> 172.30.10.22, LDP is DOWN, no binding
    Status TLV support (local/remote)   : enabled/None (no remote binding)
      LDP route watch                   : enabled
      Label/status state machine        : local ready, LruRnd
      Last local dataplane   status rcvd: No fault
      Last local SSS circuit status rcvd: No fault
      Last local SSS circuit status sent: Not sent
      Last local  LDP TLV    status sent: No fault
      Last remote LDP TLV    status rcvd: None (no remote binding)
      Last remote LDP ADJ    status rcvd: None (no remote binding)
    MPLS VC labels: local 532, remote unassigned
    Group ID: local 0, remote unknown
    MTU: local 1500, remote unknown
    Remote interface description:
  Sequencing: receive disabled, send disabled
  Control Word: On (configured: autosense)
  VC statistics:
    transit packet totals: receive 0, send 0
    transit byte totals:   receive 0, send 0
    transit packet drops:  receive 0, send 0

 

 

Long story why it is this way, but I can't change the underlying design at this time.

did you try using a VFI?

What is it that you need to accomplish please?

Connecting L3 interface in a VRF into a PW can be done with PW-HeadEnd feature.

I have the same problem, but I am afraid, that this is impossible:

Restrictions for MPLS Multi-VRF

Label distribution for a given VPN routing and forwarding (VRF) instance on a given router can be handled by either the Border Gateway Protocol (BGP) or the Label Distribution Protocol (LDP), but not by both the protocols at the same time.

So, I will try only with BGP (because of tunnel label information), but I am not sure if it will work.
