[c-nsp] Sup720 dropping LDP neighbourships

2013-05-24 Thread Grischa Stegemann
Hi all Today we were facing a ddos attack with approx. 1.5 GBit/s and 3 Mpackets/s. The traffic came in on a port of a 6704 and went out on another port of the same linecard. We have two annoying phenomena to deal with: 1. The 6509 is equipped with a Sup720-3BXL and DCEF on all linecards. During
