### 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
