When terminating PPP into VRF using Accel-VRF-Name radius attribute and with Framed-Route attribute in the radius reply message, the route provided by radius is installed into default routing table instead of the appropriate table corresponding to the VRF.
Example. Access accept packet:
```
[2022-04-27 15:00:00.303] : fe1b34439de428b9: recv [RADIUS(1) Access-Accept id=1 <Service-Type Framed-User> <Framed-Route "**192.168.255.0/24**"> <Accel-VRF-Name "**client100**">]
