2. Revision of 03 version
03 version claims ISIS-autoconf mostly fit for small networks.

3. Revision of 04 version 1/2 (04 hasn’t been published yet)
Improved the Double Duplication Detection mechanism
DD-LSP : an LSP indicates Double-Duplication happens
DD-state : a boolean which indicates if a DD-LSP #0 has been received
DD-count: the count of the number of occurences of reception of a DD-LSP
DD-timer: a timer associated with reception of DD-LSPs. Recommended value is 60 seconds.
DD-max : the maximum number of DD-LSPs allowed to be received in DD-timer interval. Recommended value is 3.

4. When a DD-LSP is received:
If DD-state is FALSE
DD-state is set to TRUE
DD-timer is started
DD-count is initialized to 1.
If DD-state is TRUE
DD-count is incremented
If DD-count is >= DD-max:
Local system MUST generate a new System ID and Router-Fingerprint and restart the protocol. DD-state is (re)initialized to FALSE and DD-timer cancelled.
If DD-timer expires:
DD-state is set to FALSE

5. Revision of 04 version 2/2 (04 hasn’t been published yet)
Specified some parameters in ISIS-autconf default configuration
originatingLSPBufferSize is set to 512.
MaxAreaAddresses is set to 3
Extended IS Reachability and IP Reachability TLVs MUST NOT be used i.e. a router operating in auto configuration mode MUST NOT use any of the following TLVs:
IIS Neighbors (2)
IP Internal Reachability (128)
IP External Reachability (130)

6. Next Steps
Upload the 04 version for review
Then move forward to WGLC?
