# Traffic Engineering

Traffic Engineering (TE) is possibility to send traffic from node to node using
alternative path.

## Common link parameters

Traffic Engineering parameters are used for both IS-IS and OSPF (not supported
yet).

```{cfgcmd} set protocols traffic-engineering admin-group \<admin-group-name\> bit-position \<bit-position-value\>

Create Administrative group and associate bit position with it. These groups can be
used in the following commands.

\<bit-position-value\> can have value 0-31. There cannot be two groups with same bit position.
```


```{cfgcmd} set protocols traffic-engineering interface \<ifname\> admin-group \<admin-group-name\>

Set administrative group for interface \<ifname\>. Multiple values can be provided.
```


```{cfgcmd} set protocols traffic-engineering interface \<ifname\> max-bandwidth \<max-bandwidth-value-mbps\>

Set maximum bandwidth for interface \<ifname\>. Value given in Mbits per second.
```


```{cfgcmd} set protocols traffic-engineering interface \<ifname\> max-reservable-bandwidth \<max-reservable-bandwidth-value-mbps\>

Set maximum reservable bandwidth for interface \<ifname\>. Value given in Mbits per second.
```

## IS-IS TE Configuration

Traffic Engineering (TE) can be enabled and exported for IS-IS
using the following commands:

```{cfgcmd} set protocols isis traffic-engineering enable

Enable Traffic Engineering for IS-IS.
```
```{cfgcmd} set protocols isis traffic-engineering export

Export Traffic Engineering data to neighbors.
```
```{cfgcmd} set protocols isis traffic-engineering address \<ipv4-address\>

Configure IPv4 address for MPLS-TE.
```
