MPLS Tunnel is down, create hoplist ip addr is unknown. Not really sure what configuration I have missed.

Topology, first image is how it looks in GNS3

PE1#show mpls traffic tunnels tunnel 1 Name: PE1_t1 (Tunnel1) Destination: 30.30.30.30 Status: Admin: up Oper: down Path: not valid Signalling: Down path option 1, type explicit PE1toPE2 Config Parameters: Bandwidth: 100 kbps (Global) Priority: 2 2 Affinity: 0x0/0xFFFF Metric Type: TE (default) AutoRoute: enabled LockDown: disabled Loadshare: 100 bw-based auto-bw: disabled Shortest Unconstrained Path Info: Path Weight: 64 (TE) Explicit Route: 172.16.30.3 30.30.30.30 History: Tunnel: Time since created: 3 hours, 7 minutes Number of LSP IDs (Tun_Instances) used: 283 Path Option 1: Last Error: PCALC:: Can't use link 172.16.10.2 on node 20.20.20.20 

and output of my debug mpls traff-eng path lookup shows static path verify failed and create_path_hoplist:ip addr 172.16.20.2 unknown.

Also the tunnel to my 30.30.30.30 destination is failed.

Edit: Fixed (I think) with the following

PE2:

Router ospf 1 mpls ldp autoconfig

int s3/0 ip rsvp bandwidth 1000

P:

int s3/1 ip rsvp bandwidth 1000
