you probably don't want this, bgpd picks one itself. you certainly
don't need it, it shouldn't make a differnce tho.

this might be your problem - just leave it out.

whilst fine for debugging, I doubt you want this in the long run,
syslog will likely chew more CPU logging than bgpd actually doing its
job ;)

these two are defaults anyway, I'd leave them out.

you left anything out here?
you either have an error in the filters or, well, not obvious at a
first glance.

that points to a problem with the filters, or your ISP is not adding
its own AS leftmost to the path. in the latter case, try
enforce neighbor-as no
in the neighbor spec. That would be s slightly strange setup tho unless
you talk to a route-server at an IX or the like.
