Class LinkTLV

es.tid.ospf.ospfv2.lsa.tlv.LinkTLV

public class LinkTLV
extends OSPFTLV

Link TLV from RFC 3630 (TE Extensions to OSPF Version 2). 2.4.2. Link TLV The Link TLV describes a single link. It is constructed of a set of sub-TLVs. There are no ordering requirements for the sub-TLVs. Only one Link TLV shall be carried in each LSA, allowing for fine granularity changes in topology. The Link TLV is type 2, and the length is variable. The following sub-TLVs of the Link TLV are defined: 1 - Link type (1 octet) 2 - Link ID (4 octets) 3 - Local interface IP address (4 octets) 4 - Remote interface IP address (4 octets) 5 - Traffic engineering metric (4 octets) 6 - Maximum bandwidth (4 octets) 7 - Maximum reservable bandwidth (4 octets) 8 - Unreserved bandwidth (32 octets) 9 - Administrative group (4 octets) This memo defines sub-Types 1 through 9. See the IANA Considerations section for allocation of new sub-Types. The Link Type and Link ID sub-TLVs are mandatory, i.e., must appear exactly once. All other sub-TLVs defined here may occur at most once. These restrictions need not apply to future sub-TLVs. Unrecognized sub-TLVs are ignored. Various values below use the (32 bit) IEEE Floating Point format. For quick reference, this format is as follows: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |S| Exponent | Fraction | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ S is the sign, Exponent is the exponent base 2 in "excess 127" notation, and Fraction is the mantissa - 1, with an implied binary point in front of it. Thus, the above represents the value: (-1)**(S) * 2**(Exponent-127) * (1 + Fraction) For more details, refer to [4].
