 One more!

Vendor code filter - prevent explorer packet from sent out that by vendor
portion/any portion of Mac address

700-799 48-bit MAC address access list
access-list 704 deny 0260.8c00.0000 0000.00FF.FFFF - deny's 3Com NICs
access-list 704 permit 0000.0000.0000 FFFF.FFFF.FFFF - permit all others

F's are don't care

I forgot:

Filtering to reduce unwanted traffic/explorer packets with:

dmac-output-list - mac address filter
host-netbios-out - netbios filter

Thanks for your quick response. What phrases would lead to choose one
over the other. For example:

ICANREACH/ICANNOTREACH would be for a specific mac, netbios, sap
address.

border peers if you cannot fully mesh-similar to router reflectors in
BGP

port-list - if from a serial or token interface

ring-list/bgroup - from a logical grouping

proxy explorer - when multiple connections to a single host exist.

Is ring-list perferred over port-list?

Thanks,

Art

Art,

There are a lot of ways to control the explorer frames, like static
path,
ICANREACH, ICANNOTREACH, border peers, ring-list, bgroup-list etc.
Ring-list
is for tokenring interface, Bgroup-list is for ethernet. From CCO,
port-list
is for tokenring and serial ports, but I noticed it's a valid command in
ethernet. Anyone can confirm this?
Regards,

Zhen Cai

If asked to control the flooding of explorer frames the ring-list,
port-list
and bgroup-list seem to accomplish this task.

bgroup-list applies to Ethernet. Does ring-list and port-list apply to
both
Ethernet and Token ring?

What are the pros and cons of each or how would I determine which one to
use?

Finally, how does the proxy-explorer command fit into the picture.

Thanks,

Art
