Robert:

Thanks for the good question about specifics.

Just specify one or more L3VPN/L2VPN RFC.
If you have time, you could even put it in the
context of the draft-wang-idr-vpn-prefix-orf-03.txt
specification.

Just so it is clear, I’ve included the same inline.

Hi Sue,

Item #1:  In phrases like “during import RDs are rewritten and RTs are not”,
please be specific on what vendors support and do not support.
This helps us understand how you are supporting your logic.
I am quite puzzled as to what more specifics are needed. RD rewrite on local import is the basic premise of L3VPN (and L2VPNs for that matter) architecture.

And BGP Path Attributes (including extended communities which in turn include RTs) are just copied (well linked to original paths).
[Sue]:  Give one or more RFC for L3VPN or L2VPN that specifies rewrite of RD and RT.
If you have time, you could even put it in the context of the
draft-wang-idr-vpn-prefix-orf-03.txt  specification.
these backward pointers help people link to specific cases.
Thanks!!
[Sue-end]
Item #2: When stating things like:
 “If you like to complicate your import and keep tons of  run time import stats for no legitimate reasons no one will stop you”

State as:
IMHO, “If you like to complicate your import and keep tons of
run time import stats for no legitimate reasons no one will stop you, but… “

OK. If IMHO was missing I am happy to see this prepended :)

Kind regards,
Robert
