I'm puzzled by one aspect on the implementation.. how to build your customer prefix filters.. that is, we have prefix-lists for prefix and length. Therefore at present we can only accept a tagged route for a whole block.. not good if the announcement is a /16 etc ! Now, I could do as per the website at secsup.org which means we have a route-map entry to match the community before the filtering .. but that would allow the customer to null route any ip. What we need is one to allow them to announce any route including more specifics of the prefix list - how are folks doing this? Steve On Wed, 3 Mar 2004, james wrote:
Global Crossing has this, already in production. I was on the phone with Qwest yesterday & this was one of this things I asked about. Qwest indicated they are going to deploy this shortly. (i.e., send routes tagged with a community which they will set to null)
