l2tpv3 error on IPv6 local-ip
Open, LowPublicBUG

Description

Hi,

It is unclear, but the auto complete allows the usage of IPv6 onto L2TPv3 and commiting does not give any errors. However after that the interface is broken and does not come online. As a result i cannot delete it afterwords:

[ interfaces l2tpv3 l2tpeth1010 ]
RTNETLINK answers: No such device
RTNETLINK answers: No such device

delete [ interfaces l2tpv3 l2tpeth1010 ] failed
Commit failed

to reproduce, us the example from manual and replace local/remote IP's with IPv6.

Hello @kruisdraad . I trying to reproduce this issue, but without success. Tunnel works.

set interfaces l2tpv3 l2tpeth1010 address '192.168.37.2/27'
set interfaces l2tpv3 l2tpeth1010 encapsulation 'ip'
set interfaces l2tpv3 l2tpeth1010 local-ip '2001:db8::2'
set interfaces l2tpv3 l2tpeth1010 peer-session-id '100'
set interfaces l2tpv3 l2tpeth1010 peer-tunnel-id '200'
set interfaces l2tpv3 l2tpeth1010 remote-ip '2001:db8::1'
set interfaces l2tpv3 l2tpeth1010 session-id '100'
set interfaces l2tpv3 l2tpeth1010 tunnel-id '200'

Can you provide show log tail 100 after creating l2tpv3?
