Here is an old implementation for Vyatta. Moreover Jool does MAP-T, offers a kernel module, and is being implemented into nftables.

I tested vyos-1.3-rolling-202105011026-amd64.iso and everything is correct

Will take a look later today starting of with VyOS 1.4

Which proper format do we need?
For example 2 tunnels:
peer-100.64.0.2-tunnel-0
peer-100.64.0.2-tunnel-1

PBR works if we change the static route to:

Maybe related task T3505 which deletes the default route for DHCP in the commit.

Confirming that this bug is still present on 1.4-rolling-20210505111.

I have not built vyos since 2018, so my last production version was 201803051831.

@carl.byington is it working in 1.3?

19: l2tpeth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master foo state UNKNOWN mode DEFAULT group default qlen 1000
    link/ether 7e:0a:f4:5c:ef:8c brd ff:ff:ff:ff:ff:ff
    alias L2 VPN Tunnel

master foo <- foo is the VRF name

@Viacheslav it must be added in the proper order and contexts need to be entered - exited appropriately

It seems a bug with frr-reload

!

 no bgp network import-check
 exit
!
vrf foo
 ip protocol bgp route-map RMAP

Update I find an example

!
vrf foo
 ip protocol bgp route-map RMAP
 exit-vrf
!
router bgp 64500 vrf foo
 no bgp ebgp-requires-policy
 no bgp network import-check

@ernstjo
Is it supported by FRR?
Can you provide an example?

Problem is because of LSP MTU missmatch

Maybe I found the issue:

@rob it fixed in the latest 1.3 with commit https://github.com/vyos/vyos-1x/commit/c7430fbb8738d76e63a6972b7399fa39572e2254
probably just not hit at that time in 1.3-rc4

this error also occure in VyOS 1.3 RC4.

Implemented, wait for approval

Don't think this is related to the i40e driver. I think it's because vyos sees

Hi @hard, I think behavior should be another for VM. Did you try to change speed when you connected via serial?
