OK I have done that .... BUT after restarting I am now seeing .... ZEBRA: netlink-cmd (NS 0) error: Invalid argument, type=RTM_NEWROUTE(24), seq=1554090, pid=0 repeated lots of times - I am trying a reboot (as that has cleared this before ....). And after a reboot those errors have gone ... NOW I know this is normally down to the kernel routing table size... BUT I have as yet not found guidance on how to set this correctly for routers. I'm actually willing to pay for some help getting these running correctly as a one off if anyone would be interested in helping / advising ... I think the setup is close here ... Just trying to determine what I am missing ...

Hi there
I am testing FRR as an alternative to Quagga on what is a very busy core router - with multiple full table BGP Sessions.
I am currently using this on Slackware 14.2 ... I have things up and running and some of the quagga bugs seem to have been cleared which is a PLUs BUT I am seeing oddness - most obviosuly with IPv6.
Running a traceroute from a server behind it is alternating between

Thanks!
