Hi Petr,
Thanks for the response, bird is actually running in the dataplane ns:

One other thing, I am running this in a kubernetes POD, maybe this might be
affecting something.
Also can you clarify how to perform *plugin "linux_nl_plugin.so" ignore
"lcp default netns" configuration?* Should this be placed in the
startup.conf or init.conf?
I want to test without netns, I tried the following in the startup config
but vpp was crashing
plugin "linux_nl_plugin.so" {
ignore "lcp default netns"
}
I also tried using the full command in init.conf but that did not work.
