+## Overview
+The purpose of this test is to verify that FRR programs SRv6 SIDs and policies correctly into the SONiC dataplane.
+
+### Scope
+The test is targeting a running SONIC system with fully functioning configuration. The purpose of the test is to test SRv6 uSID functionality.
+
+### Testbed
+The test will run on t0 testbed.
+
+## Setup configuration
+The test requires to configure BGP neighborship between DUT and one neighbor.
+
+## Test cases
+### Test case # 1 - Verify SRv6 uSID BGP L3VPN services
+* Configure a BGP session between DUT and one neighbor.
+* Setup an SRv6 uSID L3VPN between the DUT and the neighbor.
+* Verify that the DUT programs a SID list in the SONiC data plane.
+* Verify that the DUT programs a route to steer VPN traffic over the SID list.
+* Verify that the DUT programs an SRv6 uDT6 SID to decapsulate and forward the VPN traffic received from the neighbor.
