Inter-AS Option C and RSVP?

Question

VPN

Hello colleagues.
I'm trying to set up Inter-AS Option C with the distribution of labels via RSVP.
The scheme is as follows:

Inside the AS, LDP or RSVP is used for label propagation, between ASBRs, MPLS labels are applied with the help of policies.
As far as I understand, the scheme at which in one AS RSVP, in other LDP is quite possible.
If I configure LDP in both ASs, everything works. With RSVP, LSPs are built in the local AS, but MP-BGP peering does not go up between PEs of different ASs.
I assemble the circuit on Huawei equipment, but I think it doesn’t fundamentally differ in terms of settings.
What I did:
1) Enabled MPLS TE and RSVP globally
2) Enabled MPLS and RSVP on interfaces.
3) Created two tunnels: from PE to ASBR in local AS and vice versa: from ASBR to PE.
I want to note that a ping is sent from the local PE to the remote one, but does not return back (there is LS from PE1 to PE2, but not in the opposite direction).
Config for all devices.
Maybe someone has a working config of such a scheme?

Answer 1

What does "peering not going up" mean?

Answer 2

An MP-BGP session is not established between PE1 and PE2 either in public or in VPN.
When using LDP, this is the order: first, an LSP is built from PE1 to PE2 (and vice versa), after which peering is established.
And as in case of RSVP I do not know.
