3. Forgetting sequence numbers Suppose A  D via B, C  D via B Suppose B reboots and forgets everything Suppose A does not know this yet If B sends RREQ to C a routing loop results A B C D

4. DELETE PERIOD Long enough for B’s neighbors to find out that links to B have broken After neighbors find out, they maintain last sequence number for at least DELETE_PERIOD After reboot, B sends RERRs in response to receiving any data packets Lifetime of route assumes dual role

5. Multicast – after reboot A node loses all of its multicast tree info Broadcast a MACT with ‘R’ bit set Upstream neighbors delete the node from any relevant lists of next hops Downstream neighbors try to rebuild their tree branch

6. IP Address Autoconfiguration Some nodes may not have IP addresses Following zeroconf idea, try 169.254/16 Pick an address from upper 62k range Perform duplicate address detection by sending RREQ for that address For source address of RREQ, pretend to be a node in lower 2k range Sequence numbers to be zero

7. Other details Assigned type numbers for extensions Changes appendix added Typos, improvements Corrected sequence number handling in RERR message

8. Other issues IPv6 versions for messages by next IETF Should RREQ/RREP contain source routes? –if so, how long should route information persist? Rethink service discovery extensions?
