Hi all,
The following scenario:
e0--R1-----R2--e0
R1 peer R2 with DLSW, And I want R1not send netbios explore frame to R2 and R2 not send netbios explore frame to R1.So Can I use a netbios access-list in the e0 interface to bar the netbios packet so that R1 will not send explore frame out and also do that in R2 to meet the target? And Should I just use "dlsw icanreach netbios-exclusive" int the config mode in R1 and R2 to meet the target? Anybody has idea? Thank You!
Best Regards

The usual method of restricting netbios is using a SAP filer to deny the netbios SAP of F0, eg
access-list 200 deny 0xF0F0, 0x0101
access-list 200 permit 0x0000 0xFFFF
You can apply this either on the lan eg
bridge-group 1 input-lsap-list 200
or on the DLSW remote-peer command itself with the lsap-output-list parameter.
bridhe 1 or to the DLSW peer using the

Hi,
Thank You for your answer. But if I apply the access-list to the remote-peer, will the list also bar the explore frame? Thank You!

Dlsw icanreach netbios-exclusive is exactly what you're after. If you define the available netbios names on each router, these are advertised to the dlsw peer during capabilities exchange, and no netbios explorers are forwarded at all.
