[c-nsp] GSR: 3GE-GBIC-SC v4 traffic influenced by v6 traffic?

2010-02-26 Thread Sascha Pollok
Good day, the 3GE-GBIC-SC card does IPv6 in software on the linecard. Is anyone aware of a problem that IPv6 traffic that is software-forwarded could influence IPv4 hardware forwarding? It looks like a linecard could hit 100% with ~80 Mbit/s of v6 traffic + other tasks like TAG Stats Backgr or

Hello Jan, thanks for your reply. It sheds some light on that annoying problem. forwarding IPv4 traffic or AT LEAST stops responding to ICMP Echo (directed to the interface IP) or loses IP protocols like LDP or OSPF which could point to problems GRP/PRP - Interface. It seems like this happens
