Run ./configure with a --enable-multipath=X Where X is not 1.

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.

Richard - You use sysctl to increase the number of route entries, on my home system I have this: sharpd@robot ~/f/zebra> sysctl net.ipv4.route.max_size net.ipv4.route.max_size = 2147483647 sharpd@robot ~/f/zebra> sysctl net.ipv6.route.max_size net.ipv6.route.max_size = 4096 sharpd@robot ~/f/zebra> To set these values: sharpd@robot ~/f/zebra> sudo sysctl -w net.ipv6.route.max_size=8192 [sudo] password for sharpd: net.ipv6.route.max_size = 8192 sharpd@robot ~/f/zebra> sysctl net.ipv6.route.max_size net.ipv6.route.max_size = 8192 sharpd@robot ~/f/zebra> These are temporary values. To modify at reboot edit /etc/sysctl.conf with the value you want. I've also sent you a slack invite so you can log into slack and discuss this there for a quicker resolution. donald On Tue, Jun 13, 2017 at 6:16 PM, Richard J Palmer <richard@merula.net> wrote:
