[ixpmanager] Filtered because Transit Free ASN

[Ian Chilton]

Hi,

It's a safety net. Generally Tier 1 networks do not connect to an IX or 
peer with route servers, so if a route is seen with a tier 1 in the 
path, it's been accidentally leaked.

However, occasionally they do - we had this in the past with 6461.

If the network you are having problems with peers at a lot of IXPs, then 
there may be a case to remove it from the list. If not, then you can 
always override the list in your install.
