It used to be the case that looped routes didn't even show up as
hidden routes, because Junos discarded them even from Adj-RIB-In,
although this may have changed at some Junos version.
Also, Junos won't even advertise such looped routes to a neighbor with

us know.

Hi Joel,
It is right that the BGP route containing the local ASN will be droped.

can run show route hidden terse aspath-regex .*local ASN.* on
Juniper to check them. We are looking for those routes. If you can run
