Hi,
there can be a few misconfigurations:
1. "lcp default netns dataplane" start synchronizing interfaces/address/etc
inside netns "dataplane" (netns "dataplane" must exist) - NOT synchronizing
routes
2. plugin "linux_nl_plugin.so" ignore "lcp default netns" configuration =>
"linux_nl_plugin.so" will synchronize VPP with default namespace "0"
Solution with netns:
0. Create netns "dataplane" with systemd
1. run VPP inside netns "dataplane" (edit systemd, start after previous
point)
2. run Bird inside netns "dataplane" (edit systemd, start after previous
point)
3. do not use "lcp default netns dataplane", it is controlled by VPP netns
For running without netns only skip "lcp default netns dataplane".
