5.1.2.BASE

Description (partial)

Symptom:
XR allows an exactly same (same IP addresses , groups etc) VRRP and HSRP config on the same 
interface. In the the XR architecture (where VRRP and HSRP are separate processes without any knowledge about each other) the process independence prevents cross checks, but this DDTS documents what would be a misconfiguration  which would prevent operation.
