Bridge Forwarding Table

17-18
The Bridge Forwarding Table is used to match MAC addresses with Bridge ports on
which to forward frames. If an address is not found in the table, the frame will be for-
warded out all Bridge ports except those configured for native LLC-2.
All MAC addresses are in non-canonical (Token Ring) format.
As a frame is received, its source and destination MAC addresses will be added (if not
already there) to the table. (If received from a Token Ring, the addresses will be bit-
swapped [described under "Host MAC Address" on page 8-23] when added to the
table.) The FRX/FRM software contains a set of reserved MAC addresses that are
considered "static," and will always be in the table. The remaining entries are con-
sidered "dynamic," and will remain in the table for the time period configured as the
in Bridge Node Defaults (described on page 13-5).
