[vpp-dev] Ipv6 neighbor not getting discovered

2019-12-03 Thread Rajith PR
Hello Team, During integration of our software with VPP 19.08 we have found that ipv6 neighbor does not get discovered on first sw_if_index on which ipv6 is enabled. On further analysis we found that, it is due to radv_info->mcast_adj_index being checked against "0" in the following code :- Func

Hi Dom, I’ve never tried to run the stack in a VM, so not sure about the expected performance, but here are a couple of comments: - What fifo sizes are you using? Are they at least 4MB (see [1] for VCL configuration). - I don’t think you need to configure more than 16k buffers/numa. Addition
