Hello Ben and others,

I have a physical hybrid testbed network with OVS switches (i.e. Pica8
hardware switches) as MPLS label edge routers and Juniper MPLS switches as
core MPLS label switching routers.

I want the edge OVS switches to push MPLS labels on to the incoming flow
traffic and the core Juniper switches to switch that traffic based on the
incoming labels and configured LSPs. I have configured static LSPs on the
Juniper switches and I know the exact label - flow traffic bindings for
each LSP.

I have tested my hardware OVS switches for pushing the MPLS labels on to
the incoming flow traffic (i.e. I have checked the Pica8 hardware flow
tables for this). They seem to push the labels on to the incoming flow
traffic.

Somehow, this MPLS label pushed traffic is not being switched and/or
matched by the incoming MPLS label and configured static LSPs in the core
Juniper MPLS switches.

Can any one of you tell me the reason for this behaviour, or am I missing
something here ?

I presumed that MPLS label format is vendor-independent, am I correct ?

Let me know, how to debug this issue.
