Connecting 2 core switches and STP

Hello networking guru's,

​

so i am trying to figure out how the best way would be to set up the following:
- 2 core switches, 2 different companies.
- STP needs to work for both companies but should not interfere with the other.

​

Normally i would choose to place a router in between the two core switches but in this case it is not a possibility. The switch managed on my end is a Huawei CE6810 (running "stp root primary") and i think i need the following commands (on the uplink to the other core) to achieve what i want/need:

stp disable
stp bpdu-filter enable (does this even make sense if i disable stp?)

​

Is this enough to achieve what i want? I have no control over the other core switch so i can not confirm its config but i want all incoming bpdu's ignored, and send none their way. But i don't want the port to go down either.

To my understanding using "stp edged-port" here would shut the port as soon as any bpdu's are being noticed is that correct?

​

Thanks in advance.
