As mentioned in both [1] and [2] this is especially critical as at present Cisco IOS will tear down sessions when receiving an AS4_PATH containing an AS_CONFED_SET/SEQUENCE.
Hi, Whilst this is behaviour is RFC compliant, as previously described, it is sub-optimal operationally. I have raised this issue with Cisco TAC, and CSCsx10140 has been opened to track this problem. I would encourage those network operators who may be planning to deploy AS4-support and use Cisco equipment to open a SR with Cisco, tracking this bug, to try to ensure that both the IOS behaviour, and RFC are changed.
