Hi all,
As defined in [RFC8231], the length of LSP Object Flag field is 12 bits and it
defined the value from bit 5 to bit 11.
The bits from 1 to 3 are defined in [RFC8623] and the bit value 4 is used in
[RFC8281]. So all bits of the flag has been occupied as the following shown.
I noticed many other drafts have extended the flag, for example,
draft-li-pce-sr-path-segment defined a new P bit.
But no unused bit can be assigned for it. So I propoese a new
LSP-EXTENDED-FLAG TLV for LSP object to extend the
length of the flag as the following shown.
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
