Cisco Switch is taking root on our HPE Comware core switches

Good Day

We have a ISP that we are trying to bring online using 3 vlans but when the link is up, their switching environment becomes root and it causes topology changes and spanning-tree problems. I have enabled stp role-restriction to avoid this but now the port is a Alternate Port (Boundary) and I can't send or receive any traffic. I don't believe there is anything on my end and that the ISP needs to change their config. I wanted to know if anyone else has dealt with this. The port in question is discarding and I can't bring it out of the restriction because it will start flapping the network across all my client vlans, which is what was happening.
