Hello

Don't you have enabled option rfc1583compat ? That would cause such behavior.

Do you have messages 'LSAID collision for ...' in bird log?

If the rfc1583compat option is not the cause, you could post 'show ospf state'
and 'show ospf lsadb' to see whether there are LSAs for both external routes.
