主题: RE: Magnus Westerlund's Discuss on draft-ietf-i2rs-yang-l2-network-topology-14: (with DISCUSS)

Hi All,

This was on the agenda to be discussed in the IEEE Yangsters meeting on Weds 9th, but unfortunately that meeting was cancelled at short notice.  I'm hopefully that this can be discussed in next week's Yangsters meeting (16th).
	
My hope is for an agreement in that meeting that sufficient review has been down and any necessary changes have been made, such that the document can continue to progress in IETF without requiring any formal liaison statement between IEEE and IETF.

I attend the Yangsters meetings on a semi-regular basis anyway, plan to attend next week, and was intending to feedback the meeting conclusions via Martin.

Regards,
Rob
