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

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.

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

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)
