+### SRv6
+
+The **SRV6_MY_SIDS** and **SRV6_MY_LOCATORS** tables introduce Segment Routing over IPv6 configuration.
+An example is as follows:
+```
+{
+    "SRV6_MY_LOCATORS" : {
+        "loc1" : {
+            "prefix" : "FCBB:BBBB:20::"

+    }
+    "SRV6_MY_SIDS" : {
+        "loc1|FCBB:BBBB:20::" : {
+           "action": "uN"
+        },
+        "loc1|FCBB:BBBB:20:F1::" : {
+           "action": "uDT46",
+           "decap_vrf": "default",
+           "decap_dscp_mode": "pipe"
+        }
+    }
+}
+```
+
 ### FIPS
 
 The FIPS table introduces FIPS  configuration.
