Hello

These are not errors, these are log messages enabled by 'debug all'.

The only unexpected thing is that received routes are marked as
unreachable. That is most likely because an IP address from route
attribute bgp_next_hop cannot be resolved in your routing table
But there should be routes learned by kernel protocols. What
is your output of 'show route all' command?
