es.tid.ospf.ospfv2.lsa.tlv.subtlv.AdministrativeGroup

public class AdministrativeGroup
extends OSPFSubTLV

Represents Administrative Group Sub-TLV, as defined in RFC 3630. The Administrative Group sub-TLV contains a 4-octet bit mask assigned by the network administrator. Each set bit corresponds to one administrative group assigned to the interface. A link may belong to multiple groups. By convention, the least significant bit is referred to as 'group 0', and the most significant bit is referred to as 'group 31'. The Administrative Group is also called Resource Class/Color [5]. The Administrative Group sub-TLV is TLV type 9, and is four octets in length.
