Mapping label bindings to LSPs on P routers without LDP

Hey all,

I’m trying to figure something out. We have a big old MPLS network with a bunch of core/P/label transit routers in the middle of the network swapping labels for our PE routers that are passing traffic for LSPs that connect l2/l3vpns and other things like 6PE.

We export IPFIX with mpls templates from these guys, and we mostly get the whole label stack. But these mean nothing to our flow collection devices because they are literally ephemeral label stacks and have no context like “label 435 is heading out interface blah towards a.b.c.d/xx”. Since our collector isn’t on the same network, I don’t think we can get this from ldp (maybe I’m wrong?). Any suggestions for how I could “enrich” these flow records with lsp/label bindings?
