Just some more info I've collected. Let me know if this is accurate.
Art
Peer groups/Border peers - eliminates the requirement to be fully messed
when communication is needed branch to branch, one branch sends out a
single explorer packet (instead of one to each TCP connection) to the border
router and the border router forward the packet for the branch to the other
remote peers. Simliar concept to BGP route reflectors.
proxy explorer is not needed with DLSW+, it's built in.
______
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
0's must match

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 - for both token and
ethernet. used if peering between token and ethernet.
ring-list/bgroup - from a logical grouping
Ring list over port list - easier to configure if you have many routers.
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
