Hi, could someboby explain me what are the pre-defined addresses in the
the address filter section on a DECswitch 900Ex. The addresses in the
switch I am working with are in the following range:
- 01-80-C2-00-00-00 to 01-80-C2-00-00-oF
- 08-00-2b-96-F0-68 to 08-00-2B-96-F0-6E
- 09-00-2B-01-00-01
Thanks, Yves.

| 3472.1 | 01-80-c2-00-00-00 is the Bridge hello multicast | EDWIN::TOMG::gulick | Those dirty rings !! | Wed Apr 17 1996 15:57 | 6 |
The first range is defined in 802.1d standard (MAC bridging) as reserved for use by bridges and to be always filtered. I suspect the other addresses are similarly specified in some other standard. -tom | |||||

01-80-C2-00-00-00 This is the IEEE 802.1d cross-company multicast
Bridge group address.
01-80-C2-00-00-01 to These are also IEEE 802.1d cross-company multicasts
01-80-C2-00-00-oF reserved (always filtered by bridges).
08-00-2b-96-F0-68 to These are probably the 7 addresses of the 7 ports
08-00-2B-96-F0-6E of the specific bridge you are looking at.
09-00-2B-01-00-01 This is an "All Local Bridges" multicast address
assigned by Digital.
These can be found along with many other LAN addresses in the Ethernet
Registry documents located at the following public area.
FILES::NET$ARCH:[REGISTRY]
There are versions of the Registry which are for *Internal Use Only*
and other public registry documents at this same pointer.
Enjoy....
Bob
