[c-nsp] BGP Communities - Sample Configs

[Paul Stewart]

Thanks for all the replies.... I'm actually looking for IOS config showing
how to take a community being sent from a customer and apply that towards a
community received from an upstream for example.  Furthering that a bit, if
I wanted one of our downstreams to be able to prepend their IP space
specifically towards one of our upstreams or perhaps not advertise at all...

This all seems to be route-map driven but can't quite figure out the total
picture ...

Thanks,

Paul

There are some good links to the ISP policies on the nanog site:

Hi folks...

I'm looking for a site or info on BGP communities.  I have a fairly good
understanding I think, we use them on some upstreams today to influence
routes etc.....

My question is that now we want to implement BGP communities in our network
core.  This way our BGP customers can influence routes to our upstreams and
peers.  Anyone have any good resources on this as I'm missing a small piece
of the puzzle and/or best practices on implementing?

Thanks,

Paul
