Section 5.7 says:
vvvvvvv v | OSPFv2 Options Registry (Section 2.1) Value Description Reference ----- ----------- --------- 0x01 B-bit [RFC2328] | 0x02 W-bit [RFC2328] 0x04 V-bit [RFC2328] 0x08 W-bit [RFC1584] 0x10 Nt-bit [RFC3101]
It should say:
vvvvvvvvvvvvvvvvv vvv | OSPFv2 Router Properties Registry (Section 2.4.2) Value Description Reference ----- ----------- --------- 0x01 B-bit [RFC2328] | 0x02 E-bit [RFC2328] 0x04 V-bit [RFC2328] 0x08 W-bit [RFC1584] 0x10 Nt-bit [RFC3101]
Notes:
Apparently, the headline has been erroneously copied from Section 5.1
without performing the necessary edits.
The duplicate occurrence of "W-Bit" in the table is striking -
Section A.4.2 of RFC 2328 normatively gives the correct name of bit
0x02, and the Appendices of RFC 3101 and RFC 1584 correctly replicate
the field names as stated in RFC 2328 (and its predecessors).
