public class TNAIPv6SubTLV
extends PCEPSubTLV
All PCEP TLVs have the following format:
Type: 2 bytes
Length: 2 bytes
Value: variable
A PCEP object TLV is comprised of 2 bytes for the type, 2 bytes
specifying the TLV length, and a value field.
The Length field defines the length of the value portion in bytes.
The TLV is padded to 4-bytes alignment; padding is not included in
the Length field (so a 3-byte value would have a length of 3, but the
total size of the TLV would be 8 bytes).
Unrecognized TLVs MUST be ignored.
IANA management of the PCEP Object TLV type identifier codespace is
described in Section 9.
In GEYSERS,
The format of the TNA�s TLVs is the same defined in [OIF-ENNI-OSPF] (see Figure 3.4). The following types are defined:
� IPv4 TNA: 32776
� IPv6 TNA: 32778
� NSAP TNA: 32779
The address length (in bits) is used to represent the TNA address prefix.
