General questions
1

I am new to VyOS and while learning, I’m trying to create an L2TPv3 interface on a VyOS VM, and I get this output :

vyos@vyos# sh interfaces l2tp
+l2tpv3 l2tpeth0 {

  • bridge-group {
  •    bridge br0
  • }
  • destination-port 10000
  • encapsulation udp
  • local-ip 172.31.31.2
  • peer-session-id 1
  • peer-tunnel-id 1
  • remote-ip 172.30.30.2
  • session-id 1
  • source-port 10000
  • tunnel-id 1
    +}
    [edit]
    vyos@vyos# commit
    [ interfaces l2tpv3 l2tpeth0 ]
    RTNETLINK answers: Network is unreachable
    RTNETLINK answers: No such device
    Cannot find device “l2tpeth0”

[[interfaces l2tpv3 l2tpeth0]] failed
Commit failed

vyos@vyos#

Any ideas or help is appreciated!

at 1st you should try a newer version. 1.1.7 is end of life.

Option 1 the Rolling Release:
https://downloads.vyos.io/?dir=rolling/current/amd64

Option 2 a version before the official 1.2.0 LTS release:
https://downloads.vyos.io/?dir=testing/1.2.0-rc11

or the last Option :slight_smile:

In the config i notice, that you don’t have a route to your remote-ip 172.30.30.2?
