How to forward vpn instance traffic into Tunnel if rsvp protocol used instead ldp for transport lable distrubution

Hi guys

i have a question

recently tried to realise the folowing topology

so i tried to use rstv instead of ldp for lable disstribution

betwean R1 and R3 iBGP vpnv4 peering + vpninstance (import route direct)

also there is a tunnel 0/0/0 from R1 to R2 and vise versa

could some one tell me how to forward vpn_instance traffic into tunnel

1) when ldp is used i can see that vpn_instance on both ends import igp routes received from its peer

when rsvp is used i can see that vpnv4 routes come to peer router bun not imported into vrr

please help

generally i want use rsvp intead of ldp ))
