[FROG] Getting Started...

Tue Jun 13 18:16:32 EDT 2017

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 ...

Thanks in advance

Richard
