First-hop redundancy

First-hop redundancy. The RFCs whose summary names the fhrp aggregate, with their mandatory and optional coverage.

All profiles · All RFCs

Mandatory57.8%96 of 166 (57.8%)

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

Optional1.5%1 of 65 (1.5%)

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

Mandatory ceiling91.6%152 of 166 (91.6%); excluded: Optional feature not offered (classification can be revisited): 2 of 166 (1.2%); Met by a lower layer: 3 of 166 (1.8%); Not applicable (classification can be revisited): 9 of 166 (5.4%)

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

Optional ceiling98.5%64 of 65 (98.5%); excluded: Optional feature not offered (classification can be revisited): 1 of 65 (1.5%)

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

Not walked0of 3 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: 152 of 166 (91.6%); excluded: Optional feature not offered (classification can be revisited): 2 of 166 (1.2%); Met by a lower layer: 3 of 166 (1.8%); Not applicable (classification can be revisited): 9 of 166 (5.4%). Optional ceiling: 64 of 65 (98.5%); excluded: Optional feature not offered (classification can be revisited): 1 of 65 (1.5%). Lowest mandatory ceiling: rfc9568 60 of 66 (90.9%). Lowest optional ceiling: rfc5798 25 of 26 (96.2%). 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.
