I'm having an issue with several different view on RIF decoding. One place says this: If I have a RIF of 0610 00A1 00B2 00C0 This is valid because in binary the RC fields say: 000 00110 0 001 0000 Which means: RC = 6 bytes of information which equates to 3 Ring/Bridge combo's read from left to right and a length of 1500 RD = Ring 10 to Bridge 1 to Ring 11 to Bridge 2 to Ring 12 to Bridge 0 which is always the last bridge Another place says this: If I have a RIF of 0810 00A1 00B2 00C3 RC fields say: 000 01000 0 001 0000 RC = 8 bytes of information which equates to 3 Ring/Bridge combo's read from left to right with a length of 1500 RD = Ring 10 to Bridge 1 to Ring 11 to Bridge 2 to Ring 12 to Bridge 0 which is always the last bridge WHICH IS CORRECT? 8 bytes = 3 ring/bridge combo's or 6 byes = 3 ring/bridge combo's If I look at the RD it is 6 byes which makes me believe the first example is correct, however at http://www.cisco.com/warp/public/100/46.html and the CCIEprep token ring it shows the 8 bytes = 3 ring/bridge combo's. I understand everything else but I will miss every RIF decode question if I don't figure this out. Thanks!
