Section 184.108.40.206.2. says:
If padding bytes are needed but the algorithm does not specify the padding contents, then the padding octets MUST have a value of zero.
It should say:
The padding bytes MUST be zero. The algorithm MUST NOT specify anything else.
This is forced two times in this RFC4302, namely before in this
section 220.127.116.11.2 and in 3.4.4 .
Section 3.4.4 deals with verification of the ICV, whereas section 3.3.3 deal with generation of an ICV. Thus discussion of padding is needed in both contexts and is not redundant. The text should remain as it is.
