If the hostname setting is only a test to prove you can save the config, I suggest you try a different command for testing. I've found the hostname setting to be unreliable because FRR derives it from the kernel. I have a bug assigned to me to figure how to make it persistent but haven't gotten around to it yet.

Hi,

I have the following problem:

I'm not able save the router config.If I exit out of vtysh and jump back in, the config is reset back to defaults.

[root@frr frr]# vtysh

Hello, this is FRRouting (version 7.3.1).

frr# conf t

frr(config)# hostname Heikki

Heikki(config)# do write

Note: this version of vtysh never writes vtysh.conf

Building Configuration...

Integrated configuration saved to /etc/frr/frr.conf

[OK]

Heikki(config)# do sh running-config

Building configuration...

Current configuration:

!

frr version 7.3.1

frr defaults traditional

hostname frr

hostname Heikki

service integrated-vtysh-config

!

line vty

end

Heikki(config)# do sh startup-config

Heikki(config)# exit

Heikki# exit

[root@frr frr]# vtysh

Hello, this is FRRouting (version 7.3.1).

frr#

According to systemctl, the config save runs with code 0.

Aug 11 12:23:38 frr watchfrr[1514]: configuration write completed with exit cod0

I'm pretty sure I'm missing something very simple here, but just can't figure out what it is.

Any suggestions for troubleshooting steps?

Heikki
