OSPF

OSPFv2 and OSPFv3. The RFCs whose summary names the ospf aggregate, with their mandatory and optional coverage.

All profiles · All RFCs

Mandatory36.9%151 of 409 (36.9%)

MUST, MUST NOT, REQUIRED, SHALL and SHALL NOT rows of the walked RFCs that a recorded test break proves.

Optional4.1%10 of 242 (4.1%)

MAY, NOT RECOMMENDED, OPTIONAL, RECOMMENDED, SHOULD and SHOULD NOT rows, counted the same way.

Mandatory ceiling80.7%330 of 409 (80.7%); excluded: Optional feature not offered (classification can be revisited): 1 of 409 (0.2%); Met by a lower layer: 6 of 409 (1.5%); Not applicable (classification can be revisited): 72 of 409 (17.6%)

Attainable mandatory rows under current classifications, over the unchanged total.

Optional ceiling92.6%224 of 242 (92.6%); excluded: Not applicable (classification can be revisited): 18 of 242 (7.4%)

Attainable optional rows under current classifications, over the unchanged total.

Not walked3of 23 RFCs

RFCs with no valid extraction sign-off: their rows count in neither figure.

Mandatory registernot completeevery row proven, none unwalked

A profile is complete only when it requires at least one RFC and none of them is unwalked.

Mandatory ceiling: 330 of 409 (80.7%); excluded: Optional feature not offered (classification can be revisited): 1 of 409 (0.2%); Met by a lower layer: 6 of 409 (1.5%); Not applicable (classification can be revisited): 72 of 409 (17.6%). Optional ceiling: 224 of 242 (92.6%); excluded: Not applicable (classification can be revisited): 18 of 242 (7.4%). Lowest mandatory ceiling: rfc4576 0 of 4 (0.0%). Lowest optional ceiling: rfc4577 2 of 20 (10.0%). Ceilings describe current classifications, not an immutable Linux maximum. Not-applicable and feature-declined classifications can be revisited. Every gap remains work Ze owes.

Tree

Roots first: an RFC sits one level above the highest level of the RFCs it builds on, and the RFCs of one citation cycle share a level. Each bar is the share of that figure's rows a recorded break proves; the ceiling below it shows attainable rows under current classifications. An RFC that is not walked shows an empty bar and no figure or ceiling.
