I have two meta topics which I would like to discuss. 1) The link-attr-op-mode knob is not clear since it is neither offering detailed description nor referencing the RFC 9479 subsections. choice link-attr-op-mode { default "legacy"; >>> Why is this the default? Is that coming from RFC9479? leaf legacy { type empty; description "Only send legacy advertisements."; >>> What does this mean? Not send via ASLA but only legacy advertisements (sec 3) or send via ASLA with the L-bit (sec 4.2)? } leaf transition { type empty; description "Send both application-specific and legacy advertisements."; >>> What does this mean? Is there a reference from the base RFC on how this is supposed to work? } leaf app-specific { type empty; description "Only send application-specific advertisements."; >>> If there is a compulsion to pick a default (I think there shouldn't be one?), then I would pick this one. } description "Link attributes mode. Default to legacy mode for backward compatibility."; } Based on my understanding of RFC9479, we can only think of an enablement knob for ASLA advertisements at global level. The L-bit is perhaps something to control under the interface config under isis-asla. It could also be global if there is a desire to support hierarchical config for just the app selection (SABM/UDABM) and the L-bit setting. 2) When new sub-sub-TLVs are introduced under ASLA sub-TLV or under FAD sub-TLV, how does the current structure make augmentation of the module easy and straightforward? I am not a YANG expert and hence I would like to cross-check. _______________________________________________ Lsr mailing list -- [email protected] To unsubscribe send an email to [email protected]
