Hi, here is an issue I have been working on but no lucky..

    rL:s0 ----------------s1:rM:s0 --------------- s0:rR
 "tr < rR:s0 IP>" ACL# 100 /out
                        apply on rM:s0

Q: apply access-group 100 OUT on rM:s0 to block the output
   of traceroute from rL toward rR:s0, but allow rL ping
rR

My cfg. on rM:
 int s0
  ip access-group 100 out
 !
 acl 100 deny icmp any Any eq traceroute
 acl 100 permit ip any Any
 !
While verify, from rL: using " tr <rR:s0's IP> "
 I can still see the output from both routers: rM and rR.
 not just rM.

Was anything wrong in my cfg. ?

Thanks in advance.
