Thanks all! I have 2 related Qs:
(1) So use netbios-exclusive at R2, not sure understand how does it meet the
req that it sends ONLY hostxyx to R1 and block all other? should I include the
remote option as in below? i don't quite understand what the doc says.
dlsw icanreach netbios-exclusive remote !** "remote" option
dlsw icanreach netbios-name hostxyz
(2) I notice there is one way of using a filter at R2 LAN int:
interface Ethernet1
ip address 10.1.1.1 255.255.255.0
access-expression input netbios-host(hostfilter)
bridge-group 1
netbios access-list host hostfilter permit hostxyz
My problem is that IP is blocked once netbios filter is applied, can anyone
help to explain what's happened? in theory, how netbios filter can impact L3 IP
traffic?
TIA
