Frank :
The filter rules are as below :
Input Filter 1 :
Generic...
Forward = No
Offset = 34
Length = 1
Mask = FF00000000000000
Value = 8300000000000000 #loose source route
Compare = Equals
More = No
Input Filter 1 :
Generic...
Forward = No
Offset = 34
Length = 1
Mask = FF00000000000000
Value = 8900000000000000 #strict source route
Compare = Equals
More = No
These filters will discard incoming packets with sourece route
option.(ex:traceroute -g or traceroute -G)

Subject: source routing and Ascend P50
I have an Ascend Pipeline 50 router and would like to kill all
incoming source-routed packets.
1) Is it possible to filter source-routed packets with a P50?
2) If so, can anyone provide an example of such a filter rule?
I've spent some time on the phone with Ascend in an attempt to
answer these questions. In that hunt, I spoke with four support
people, none of whom were familiar with the concept of source
routing. (That was, in itself, a little disturbing.) I tried to
explain what source routing was and why it was of interest, but I
never did get any useful responses.
