HI Jim,

could you please send the output of show route x.x.209.0/24 detail ?

I think x.x.209.0/24 also have the community 5061 and because this it
is being denied by the first term.

Thanks

I have a new advertisement with the pass community but it is not making it out. I have soft cleared several time and I still don't see it in the wild. Any thoughts on what I am missing? Hoping it doesn't need a hard clear etc.
