Goals of this presentation:
• Clarify the objectives.
• Acquire a feeling of the WG’s thoughts about the concept.
• Answer questions about the mechanism.
• The draft is exploratory and possibly too detailed; we know it, we welcome the WG’s feedback on what needs to be removed / rewritten.

What this draft is not:• An attempt to standardize bogon filtering.
What this draft is:• A mechanism to distribute filtering information.
Bogon filtering is only one example of filtering information. The objective is to standardize the mechanism.
• Idea: re-use ORF mechanisms. The ORF specifications are not modified; what is required is a syntax enhancement that is mostly a matter of implementation.

In complement of:
router BGP 65001
neighbor bogonserver remote-as 65000
neighbor bogonserver capability orf prefix-list send
We also want the capability to do this:
router BGP 65001
neighbor bogonserver remote-as 65000
neighbor bogonserver capability orf prefix-list send THEIRBOGONS
Which is: naming the filtering object received from the peer

• The "THEIRBOGONS" object is the ORF information received from the peer.
• The reason we want to name it is because we want to reuse the "THEIRBOGONS" object in other parts of the router's configuration (for other peers).
• The object received from the peer may or may not be a prefix-list; it can be an as-path or any future ORF object.

Open mike:
Questions ?
Suggestions ?
Issues ?• Interactions between ORF and iBGP; are there any
issues with full meshes, route reflectors and confederations?
• If the ORF object received from the peer is named, should the object not be applied automatically to the peer it was received from?
