reject debug messages

[Angel]

Hello Jonathan,

We have a fullrouting bgp with a carrier and we configure it with AS174transit bpg protocol. This routes are not from our AS, they come from carrier's bgp session.


What we could not understand is why all added messages have their own rejected by protocol messages, what they mean? we disable all filters and it appears again. 


Regards,

Are those routes part of your own AS?  Is there anything special about the rejected routes?

Hello, 

We are configuring a new bird router, and after configure a carrier, we can see following messages on debug every minute:

We understand that added messages is because carrier sent us new routes, ignored looks like that we know this route, so we do not need to add to our table, but what about rejected messages?  How could we fix it? What could be our misconfiguration?
