IP routing and VRF tables

Notes

• Interfaces must NOT have IP address before assignment to VRF table!
• If VRF table was not created before assignment, it will be created automatically.

Scenarios

---

1. Assign VRF table to interface

This process assigns VRF table to interface.

1. create new interface IFACE
2. assign VRF table X to IFACE
3. set IP address for IFACE

Now the routes for the interface will be listed in the assigned VRF table.

---

2. Automatic removal of VRF table

This process assigns VRF table to interface and then changes back to default table (VRF 0).

1. create new interface IFACE
2. assign VRF table X to IFACE
3. set IP address for IFACE
4. unset all IP addresses from IFACE

Now the assigned VRF table will be automatically deleted, since no other interface uses it.

---

3. Assigning IP to deleted VRF table

This process will crash the VPP!!

1. create new interface IFACE
2. assign VRF table X to IFACE
3. add IP address for IFACE
4. delete IP address from IFACE
5. delete VRF table X
6. add IP address for IFACE

This is probably caused by some access of invalid pointer from deleted VRF table.
