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
