Regarding the IPv6-SR compatibility, as SRH is basically 'loose source routing', it only requires: - SRH processing by all SR-enabled router whose segment id is in the SRH, typically some PE routers. Those will need to be modified indeed but those will be minority - SRH forwarding (i.e. Not parsing or acting upon the SRH) for all remaining routers. Those will be the majority The latter is currently OK, I wrote a small script https://www.vyncke.org/sr.php which basically sends a dummy SRH to your browser (requirement is that your browser/clients supports IPv6) and after a dozen of tests, all were successful. While this is not a mathematical proof, this is good enough from my engineer's point of view Hope this helps -éric _______________________________________________ spring mailing list spring@ietf.org https://www.ietf.org/mailman/listinfo/spring
