These are vendor-specific.

In the RFC, it's basic I-PMSI vs. S-PMSI (data plane) or RPT-SPT vs.
SPT-only (control plane), e.t.c.

How the vendor actually implements them is unique to them (hence the
fancy names some of these sub-features end up having). If you keep the
baisc principles in mind, you'll be fine, especially in multi-vendor
