Binding SID: If the length is 2, then no Binding SID is present.
If the length is 6 then the Binding SID is encoded in 4 octets
using the format below. Traffic Class (TC), S, and TTL (Total of
12 bits) are RESERVED and MUST be set to zero and MUST be ignored.
If the length is 18 then the Binding SID contains a 16-octet SRv6
SID./
Jeffrey: Why do we need the a 16-octet Binding SID since we have the following
"SRv6 Binding SID Sub-TLV"?
Ketan (KT2): We put it up front so it is more clear - putting it at the end may
result in it being missed. This is an editorial thing and I prefer keeping
it as is.
