hi idr-dyanmic-cap-all team,

i'm happily announcing you all that we've just finished implementing the
draft in question.

from now, rare/freertr is able to turn on/off an arbitrary bgp (s)afis that
it supports.

please find attached a router of 3 networks, r1-r2-rr, where r1 turned off
then back on an mpls-vpn (s)afi...

the code is out on the internet, you can reproduce the captures by doing the
following:

wget freertr.org/rtr.zip
unzip rtr.zip
cd src
./c.sh
./tw.sh rout-bgp779.tst capture r1 eth1 capture r2 eth1 capture r3 bvi1



so from now, rare/freertr team is seeking for some interop partners if there
is one....


regarding the
https://datatracker.ietf.org/doc/html/draft-ietf-idr-dynamic-cap-16

it's well written as usual, and was easy-peasy to implement (half a week),
only one thing is that we noticed:

"
5. Error Handling
7 CAPABILITY Message Error
"
should had written as
"
8 CAPABILITY Message Error
"

because 7 is reserved for route-refresh codes for a while:


https://www.iana.org/assignments/bgp-parameters/bgp-parameters.xhtml#bgp-parameters-3


seeking for your comments about the captures,

thanks,

csaba
