Hi James,

I don't see a routing database object for your routes pointing too your

This is a really good observation, and a likely explanation!

@ OP - during IP space migrations from AS A to AS B you should ensure that route
objects exist for both ASNs.

You may also want to double check with your upstream providers what
their AS path
filters look like for your circuits.

Kind regards,

Job
