Known Affected Releases

5.1.0.BASE

Description (partial) 

Symptom:
If an ASR9k acting as a BNG attempts to terminate PPP subscriber sessions when receiving a Framed-Route attribute sent from RADIUS without a next-hop and metric string, the PPP session will fail to establish.

Conditions:
ASR 9000 acting as a BNG running IOS-XR 5.1.0, and when PPP subscriber profiles in RADIUS are configured with a Framed-Route attribute which does not explicitly specify a next-hop and metric/distance value.  

For example:  Framed-Route = "10.1.1.0 255.255.255.252"

This is not observed in XR 4.3.
