bgp default-route-advertise with policy apply community

waiting for help

what's the ip prefix tran.
"if-match ip-prefix tran" is a rule check , if match this, the actions below would be executed.
you can try to modify the ip-prefix tran to 0.0.0.0/0 or just delete if-match judgement command.

Well, that's what seems like should happen, but in actual practice, it is originating a default but without a local preference of 10, or community 65000:1.

tran is an ip-prefix list of some IP addresses, at least one of which should be present, before this router orginiates a default to the peer in question.

In your example the route-policy configured and the route policy which was applied is different, so definitely it will not work.
