Hi Brian,
Thanks for your help. I would like to clearly understand the operation of
DLSW+.
How can I configure R1 so that hosts on To1 OR R1 will not send explorer
frames to R2.
I know that I can set a destination mac address filter list and apply on R1
DLSW+. Do you know any other solution instead of mac address filter list.
Many thanks for your help.
Voller

Voller,
The icanreach on R1 is to advertise DLSW reachability information
to remote DLSW peers. The icanreach on R1 does not apply to the hosts
hanging off R1's own to1. host 1 will contact hosts, or explore for hosts
as per the reachability information on R2.
