Symptom
Currently in OC Model, since interface-name could not be mapped for VRRP Config model directly, it was manually mapped by forming interface name and index.
Now when delete request comes at ipv4-vrrp level or ipv6-vrrp level, it doesnt know whether the request is for complete interface config or just for ipv4 /ipv6 container, hence currently it deletes both ipv4 and ipv6 config as it deletes interface list for VRRP.
Need to discuss it with MGBL YAng team and find out the best possible way to fix this.
