That's excellent news - any word on when Cisco will be back-porting these
truly useful features from XR to that platform which so many of us are still
running on (ie "traditional IOS")?
The general feeling is that XR won't be ported to a lot of existing
hardware, and traditional IOS is just royally screwed (see 12.3T EOL'd
and 12.4 bloated and full of bugs, and everything older missing critical
PE functionality for unnumbered vlans).
