# Route Synchronization
The route synchronization feature keeps the kernel routing table in sync with WireGuard's _AllowedIPs_ setting.
This synchronization is bi-directional:
- Networks with are found in a Peers AllowedIP list will be installed as a kernel route.
- Kernel routes with the peers link-local IP address as next-hop will be added to the Peers _AllowedIPs_ list.
This rather simple feature allows user to pair cunicu with a software routing daemon like [Bird2](https://bird.network.cz/) while using a single WireGuard interface with multiple peer-to-peer links.
## Configuration
The following settings can be used in the main section of the [configuration file](../config/) or with-in the `interfaces` section to customize settings of an individual interface.
import ApiSchema from '@theme/ApiSchema';
