The Linux come from by my compiled kernel that supports uSID, please check my last blog: Compile SRv6 uSID and VPP on ubuntu 20.04
Before doing SRv6 lab, please double confirm enable the function by following cmd:
sysctl -w net.ipv6.conf.all.forwarding=1
sysctl -w net.ipv4.conf.all.forwarding=1
sysctl -w net.ipv6.conf.all.seg6_enabled=1
Check by following cmd:
[email protected]:/home/cisco# sysctl -a |grep net.ipv6.conf.all.forwarding
net.ipv6.conf.all.forwarding = 1
Above cmd will disappear after reboot, you can permanently write to “/etc/sysctl.conf”.
Btw, how to config srv6 and usid, reference follows:
