How to recursive L3VPN over different type of LSP

[Tim.Yu]

The questions can be stupid, but now I don't know how to allow an L3VPN to recursive over different kind of LSPs (LDP, TE, SR).

I find a way could be possible but still not fully clear.

There are path-options in tunnel-te configuration. But I cannot find a way to bind the tunnel-te with L3VPN.

Can anyone help on this?

Thanks

Good Day,

L3VPN just need to know where BGP next-hop is (for the VRF routes). That NH can be behind any transport LDP/SR/IGP. If you want next hop to be routed via Tunnel-TE then you need to add autoroute anounce config under the tunnel:
