I know TLV stands for Time, Length and Value. I also understand that:
The Version field in EIGRP packet headers is actually a protocol discriminator: a value of 1 would mean IGRP, the value 2 means EIGRP. The true EIGRP version, however, is indicated in the Version TLV.
TLV is 32 bit-triplet field that is used to carry route entries, as well as provide EIGRP DUAL information.
General TLVs
- 0x0001 - General EIGRP parameters (applies to any EIGRP packet regardless of protocol)
- 0x0003 - Sequence (used by Cisco's Reliable Multicast)
- 0x0004 - EIGRP software version, the original version being 0 and the current version being 1 (used by Cisco's Reliable Multicast)
- 0x0005 - Next Multicast Sequence (used by Cisco's Reliable Multicast)
I need more basic and granualar understanding of TLV, please assist.
Thanks,
