IDR WG

• Goals of this presentation
• Clarify the objectives.
• Acquire a feeling of the WGs thoughts about the
  concept.
• Answer questions about the mechanism.
• The draft is exploratory and possibly too
  detailed we know it, we welcome the WGs
  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?
