Hi Les, In last IETF, you presented/stated that Backwards compatibility is not possible. This seems not true. The solution proposed in draft-chen-lsr-isis-big-tlv is backwards compatible. Can you give your definition of backwards compatibility?
In this IETF and last IETF, the slides states that With partial deployment behavior is unpredictable. This seems resolved by draft-chen-lsr-isis-big-tlv. A container TLV is used by a node to contain a piece of new information. The nodes that do not support the capability of container TLV will ignore container TLVs. This will resolve unpredictable behavior with partial deployment. Best Regards, Huaimo
