You see this behavior because your traceroute program does not understand the ICMP "administratively prohibited" (ICMP type 3, code 13 - defined in RFC 1812) messages being sent back to it from cpe1.reston.mci.net. Cisco routers typically return ICMP messages of this nature to the source of traffic which is being blocked by a traffic-filtering ACL on the Cisco router. - roy - ------------------------------------------------------------------------- | roy alcala | MCI | | IP Development | 2100 Reston Parkway | | roy () mci net | Reston, Virginia 22091 | | beep-roy () mci net (pager) | (703) 715-7425 | | (800) SKY-PAGE PIN 1633689 | (703) 715-7066 FAX | -------------------------------------------------------------------------
