IEEE 802.1D, which specifies source-route bridging, supports 13 bridges, as
you say. IBM was involved in developing that specification. I was there and
I got the impression that at least the engineers at the meetings intended
for the older proprietary IBM specifications to go away. Whether that
Yes the spec says the length values are even values between 2 and 30,
but I have never seen any support for greater than 7 hops (maybe a
sheltered existence). Isn't the practical limit still the original IBM
spec with the length limit of 18? The 802.5 spec says ".. 18 bytes
being the minimum tha
The Length field in the RC field indicates the total length of the RIF.
Length values will be even values between 2 and 30 inclusive.
Source-route bridging is documented in Annex C of IEEE 802.1D MAC Bridges.
You can get it for free now from IEEE. There's no need to rely on the
sloppy work of
folks looking into RIF's might want to check out Fred Ingham's paper, found
in the Groupstudy referece lists:

the field in question is the total length of the RIF.
Much as I hate to say it publicly, Sybex and Todd Lammle books of late have
bee
All,
Is the length field in the RC of a RIF the total size of the RIF or the
total size of the RD?
According to the Rossi paper it is the total length of the RIF.
Pg 5 "Bits 12-8 (next 5) bits descrige the total length of the RIF
represented in bytes"
