yes it's all looking really hot.

> And no, nV is not (currently) all that one could hope for, like redundant uplinks are missing. I'm sure that will improve over time. (At least, that's what marketecture like this says: http://www.cisco.com/en/US/solutions/collateral/ns341/ns524/ns562/ns592/asr_nv_100611.pdf)

yes that's the one paper all googling ends up at.

I do not care too much about having to manage one or multiple chassis.

What I find interesting though is getting rid of hsrp, vrrp, glbp and all other next hop redundancy shims while having redundant uplinks to multiple chassis. Sort of like multichassis port-channels in Vss.

I am not sure yet what can of worms this opens though as I am still lacking understanding of new IOS XR concepts.

Seems we do not have to worry about vlan id signifance so much as IOS XR just pushes and pops vlan ids from subinterfaces.

Lets just hope this all comes together and we will find a way to transition smoothly ;)

Greetings
Christian
