Hi, - there is no " ignore lcp default netns" declaration in startup.conf or init.conf. If you start VPP(systemctl vpp start) with no netns configured, plugin linux_nl_plugin.so will not sync correct routing table and fail. - If you run the entire VPP process inside netns dataplane, you can skip configuration line "lcp default netns dataplane". - To make "plugin linux_nl_plugin.so" working, you need to run VPP inside netns dataplane (same as bird). This can be done by editing VPP systemd startup file (add something like " NetworkNamespacePath=/var/run/netns/dataplane" ) and ensuring that netns "dataplane" will be started first.
