Hi Vitaly,

Can you explain to me what you mean by ‘stops responding’? If you can execute 
‘sh fib mem’ that implies it’s still responsive?

Are you sure you are adding 1 million unique addresses at step 2?

Regards,
neale

Subject: [vpp-dev] Million prefixes - FIB test

Hi,
Vpp 17.04. I am trying to add 1 million prefix.
1) up interface
vpp# set int state GigabitEthernet82/0/3 up
vpp# set int l3 GigabitEthernet82/0/3
vpp# set int ip addr GigabitEthernet82/0/3 1.1.1.10/24<http://1.1.1.10/24>
vpp# set ip arp GigabitEthernet82/0/3 1.1.1.1 11:22:33:44:55:66 static
2) and repeat vppctl with cmd like
vppctl ip route add 10.x.x.x/32 via 1.1.1.1
3) check fib
vpp# show fib mem

My tests always end at ~162k prefixes and vpp stops responding.
FIB memory

        Node-list heads          8      18   /    18      144/144

What do I need to do to increase the number of FIB entries?

Thanks.
