Fields¶

Name	Type	Description
optionalBit	bool	1 bit, Optional bit. It defines whether the attribute is optional (if set to 1) or well-known (if set to 0).
transitiveBit	bool	1 bit, Transitive bit. It defines whether an optional attribute is transitive (if set to 1) or non-transitive (if set to 0). Transitive bit MUST be set to 1 for well-known attributes
partialBit	bool	1 bit, Partial bit. It defines whether the information contained in the optional transitive attribute is partial (if set to 1) or complete (if set to 0). For well-known attributes and for optional non-transitive attributes, the Partial bit MUST be set to 0.
extendedLengthBit	bool	1 bit, Extended Length bit. It defines whether the Attribute Length is one octet (if set to 0) or two octets (if set to 1).
reserved	unsigned short	4 bit
typeCode	BgpUpdateAttributeTypeCode	1 octet
length	unsigned short	2 octets or just 1 depending on the value of flags.extendedLengthBit
