Hello,
This is regarding the query for Locator TVL ,
As per the draft there is flags D (L2-L1 leaking) and A (anycast )
defined. Since there is space already exists for other flags , why
can’t R flag is not defined in the main tlv.
the A flag has been moved to Prefix Attribute Flags Sub-TLV.
R-flag is part of the Prefix Attribute Flags Sub-TLV as well.
Prefix Attribute Flags Sub-TLV can be advertised as a Sub-TLV inside the
Locator TLV.
Defining in main tlv when it had space, have some benefit as per me.
1. Many operator may opt to support main tlvs and may not support
sub-sub-tvl.
I don't understand. Either you support a particular extension or not.
You can not be selective based on what level of nesting is being used
for it.
thanks,
Peter
2. Easy implantation and inter-op can work with main tvl
implementation itself.
I understand that rfc7794 can define extended prefix attribute tlv, for
the same and Locator tlv can sent with sub-sub-tlv define in rfc7794.
