### BGP Device Global
The **BGP_DEVICE_GLOBAL** table contains device-level BGP global state.
It has a STATE object containing device state like **tsa_enabled**
which is set to true if device is currently isolated using
traffic-shift-away (TSA) route-maps in BGP
```
{
"BGP_DEVICE_GLOBAL": {
"STATE": {
"tsa_enabled": "true"
}
}

### BGP Sessions ### BGP Sessions
BGP session configuration is defined in **BGP_NEIGHBOR** table. BGP BGP session configuration is defined in **BGP_NEIGHBOR** table. BGP
