# Edit the FRR configuration file

To configure dynamic routing on the command line of the Security Engine, edit the Free Range Routing (FRR) configuration file.

##

The protocol-specific configuration file (for example, ospfd.conf) must exist in the /data/config/frr directory, and the routing daemon must be running before you configure dynamic routing using vtysh. Otherwise, vtysh cannot save protocol-specific configurations.

## Steps

1. Open an SSH connection to the command line of the Security Engine.
2. To create empty protocol-specific configuration files, enter, for example:

       sg-dynamic-routing sample-config ripd ospfd bgpd

3. To start the routing daemon, enter:

       sg-dynamic-routing restart|force-reload

4. To start the FRR command shell, enter:

       vtysh
