  1. Link-local security J.W. Atwood, S. Islam, S. Maziar PIM Working Group 2008/03/11 bill@cse.concordia.ca

  2. draft-ietf-pim-sm-linklocal-03 • Minor changes • Added empty IANA Considerations • Additional author • Some housekeeping • New Stuff • Section 10 on “IPsec Protection Barrier and GSPD”

  3. Recent activity • (Not yet reflected in the draft) • We have a much better understanding of common features among OSPF, PIM-SM and RSVP •  an idea for extending GDOI for our use •  ideas on controlling adjacency

  4. Protection Rules • Manual • We give the SPD and SAD rules for the manual case • Automatic • Rules will be in the GSPD • SAD rules will be dynamically allocated • Precise rules will come once the adjacency model is determined

  5. SPD Table entry • To protect outgoing link-local packets

  6. SAD Table entries • To protect incoming link-local packets • If single shared key, lines 2-4 merge, with Remote address = “any”

  7. Plans • Complete the exploration of the adjacency control issues • Once the (sub-) problem of “adjacency control issues” is better understood, find the right partners to create a problem statement • Attend the “kmart” BOF • Key Management for Routing Protocols

  8. ..2 • Present needed extensions for GDOI (to the MSEC wg) and ask for interest • Extend the link-local Internet Draft to use these GDOI extensions (in PIM wg)

  9. Questions?
