IPv6 RAs cause issues on asr9k

Hi,

 

Im working with asr9k running 4.3.4 and I performed various ipv6 lab tests. when I flooded the asr9k box with multiple ipv6 router advertisements, the box didn't quite survive. Ospfv3 adjacencies went down, I think as a consequence of neighbour discovery packets being dropped, as ospfv3 adjacencies didn't go down straight away. IPv4 remained running ok.

 

Looks like LPTS didn't help either as it possibly doesn't differentiate between RAs and other Neighbour discovery packets ? 

Now in my case I don't need RAs at all, no SLAAC or DHCPv6 required, so it's looking silly that something not required on the box can cause so much harm.

Hoping some of the experts here can show me if I'm missing something in terms of how to handle this

 

thanks

 

Mark
