Need help with MPLS-TE on v7

RouterOS Forwarding Protocols
1

Hi, I’m trying to experiment with MPLS on RouterOS V7.20.2 and encountered some weird issues while implementing traffic engineering in the MPLS network.

I tried to read the documentation about traffic engineering, but the help pages are quite old and don't seem to have been updated since being migrated from the old wiki. I can’t find configuration examples on the new wiki, and the old wiki is no longer accessible.

Could MikroTik staff please update the information on how to configure TE tunnels?

Also, when I try to create a tunnel, the OSPF or BFD process seems to crash. All OSPF, BGP, and BFD sessions go down and reestablish about every minute.

At the moment, it's all CLI and you can no longer assign an IP to a TE interface and use a static route (like ROSv6)

I would start here: MPLS TE on v7.19.1 - RouterOS / Forwarding Protocols - MikroTik community forum

I’ve also read that post, but not much help.

/mpls/traffic-eng/flow/print shows nothing, maybe because of the OSPF process keeps crashing.
