Hai all,
First of all, I am not sure about what the accurate answer to this problem
is, so any hints and suggestion are welcomed.
I am refering to Step ( on FatKid 441)
11. Configure a SAP filter on R4 and R3 to keep NetBIOS names from being
received from the Token Ring network.
and in the solutions Derek filters all from token ring SNA traffic,
"
interface TokenRing0
source-bridge input-lsap-list 200
no shutdown
!
access-list 200 permit 0x0000 0x0D0D
"
>From CCO I gathered that the netbios traffic uses SAP values of F0 and F1.
Even I filter out "0xF0F0 0x0101" it will filterout all netbios traffic.
So I think something like following could be the better solution:
!
netbios acess-list host FilterName deny *
int to 0
netbios input-access-filter host FilterName
!
Please comment
Thanks in advance
