Not really following the question but I'll take a stab.
In summary CRF's are attached to a parent BRF. What looks like an
ethernet VLAN is the sum of one parent TrBRF and it's children TrCRF.
CRF's talk to each other via SRS or TB thru the parent BRF. For one BRF
to talk to another requires an external device, i.e. RSM.
I can't recall if the CRF is input in hex or base10. The ring number
is important in that the children of a ring, CRF, all belong to the same
BRF and that if there are other bridges/routers on the ring they must
match.
