### IPv4 forwarding
To be able to route (static or dynamic) on the interface it is
required to enable forwarding. This setting controlls if packets
received on this interface can be forwarded.
```
admin@example:/config/> edit interface eth0
admin@example:/config/interface/eth0/> set ipv4 forwarding
admin@example:/config/interface/eth0/> leave
admin@example:/>
```
### IPv6 forwarding
This flag behaves totally different than for IPv4. For IPv6 the
ability to route between interfaces is always enabled, instead this
flag controls if the interface will be in host/router mode.

### View routing table
The routing table can be viewed from the operational datastore over
NETCONF or using the CLI:
