Hi all,
I have some concerns with regards to the deployment of this extension in brownfield multi-vendor networks as this could result in the formation of persistent forwarding loops. As a constructive proposal, and as mitigations, I would like the document be improved with the following changes: 1. Sending MUST be controlled by configuration [1] 2. For existing TLVs (and "any level of sub-TLVs"), details the TLV which could be advertised with no risks for the network and TLVs which must not be advertised before all nodes be upgraded. 3. Given this document typically may require global support before this be enabled, I think this draft would be a good candidate for the addition of the relevant yang module as per draft-qgp-lsr-isis-pics-yang [3]. I personally don't see a problem with adding a normative reference to an individual draft, but if I'm wrong, an option for the chairs to consider would be to pause this adoption call and start an adoption call for draft-qgp-lsr-isis-pics-yang. Some of those comments are not new and have already been expressed on this list [2] I would welcome the feedback of authors on the above proposals before the end of this WG adoption call. Thanks, Regards Bruno [1] OLD: It is RECOMMENDED that implementations which support the sending of MP-TLVs provide configuration controls to enable/disable generation of MP-TLVs. NEW: It is REQUIRED that implementations which support the sending of MP-TLVs provide configuration controls to enable/disable generation of MP-TLVs.
