Hoi,
Does the same behavior happen with linux_cp_plugin and linux_nl_plugin
enabled instead? I saw a change in linux_cp that will walk the fib and
remove routes associated with down interfaces; and I think this is because
FRR does not remove them while Bird does. Can you try with

Preferred/supported build platform is Ubuntu LTS. It'll build well on
Ubuntu Focal and Jammy. I additionally build and run on Debian Bullseye,
which works well.

Can you be more specific on 'statistic data extraction' What numbers/data

Take a look at the 'stats segment' which you might address read-only using
/run/vpp/stats.sock or mount as a FUSE filesystem with

Hoi Baurine,
Do you happen to have the ability to tcpdump on the DHCP server? I am
confident that linux-cp (and the lcpng) will forward this traffic out
because it's a broadcast packet (and all traffic will be handled), but I am
not confident that the packet is (a) arriving at the DHCP server and

Linux CP forwards all (unicast, multicast, ARP) through the TAP tunnel to
the Linux kernel. It's not possible to add a classifier that selectively
forwards some but not all traffic. Matthew mentioned in a thread about NAT

Hoi,
I would suggest not matching (only) MAC but (foremost) the ethertype, and
then punting those packets into the TAP, take a look at VLIB_REGISTER_NODE
(lip_punt_node) in src/plugins/linux-cp/lcp_node.c, contributions are
welcome.

Linux CP supports ARP, IPv4 and IPv6. ISIS uses its its own ethertype, as
do other protocols (like LLDP for example). Those will not be punted into
the TAP by the plugin (and it's difficult to uniquely identify the ethernet
frames that should be punted as compared to being handled entirely

I noticed that the acl-plugin will allow to replace an existing ACL using
the API, but not while using the CLI.
As well I see an acl_del API call, but no equivalent CLI. I've added them

Hoi folks,
I was diagnosing an issue today and needed to see some traffic that was
traversing an l2xc between a sub-int and a vxlan_tunnel.
Take the following simple config:
create vxlan tunnel src 194.1.163.5 dst 194.1.163.1 instance 11 vni 10502
decap-next l2
create sub GigabitEthernet4/0/0
Hoi Brian,
I think that Linux CP does not consume the netlink message that assigns the
interface to a new VRF (table)- doing it the other way around will likely
work better.
It would be pretty slick if "sudo ip link set dev ge0 master vrf-blue"
could pivot the VPP-side interface into the correct

Hoi folks,
I noticed that linux-cp plugin is not quite right with endianness:
Example code:
lcp_add = vpp.api.lcp_itf_pair_add_del_v2(is_add=True, sw_if_index=17,
host_if_type=VppEnum.vl_api_lcp_itf_host_type_t.LCP_API_ITF_HOST_TAP,

+Matthew Smith and +Jon Loeliger can
you let me know what you think?
Does Netgate value the 'lcp default netns' or ability to create LIPs in a
namespace other than 'dataplane'?
As I described, I think the ability to change these in the API, or set them
in 'lcp create' yields erratic behavior.
Hoi,
I've had a few instances of a recent VPP hanging - API and CLI go
unresponsive, forwarding stops (at least, I think), but the worker threads
are still consuming CPU.

Hoi,
Also worth noting, several sockets are created in /run/vpp/* notably the
API socket /run/vpp/api.sock - the second invocation of "vpp" may have
overwritten the socket with a new one, rendering the existing first
invocation of "vpp" unusable.

Hoi,
I am starting to work on a few APIs and noticed that the vpp_papi module's
method find_api_dir promises that it will include VPP_API_DIR first, if
specified in the environment. It doesn't actually do that.
I wrote a changelist that prepends VPP_API_DIR if it exists. This is

Hoi Petr,
I think that the keys in the wireguard plugin are represented
as bytestream, and your 44 character string probably refers to its base64
representation. Try sending the raw key (32 bytes).
As an aside, I thought I'd ask ChatGPT this question, because I thought it
was a fun puzzle.

VPP does not run on that board, because the soc does not enumerate its DPDK
enabled interfaces on the PCIe bus, but rather has a custom bus, which VPP
is not integrated with.
Incidentally, I did get VPP itself to run but without DPDK (or AVF or etc)
interfaces; and its basic functionality
Hoi Konrad,
Looking at your configs, gre0 will have been created as an L3 interface. If
you'd like it to be an L2 interface, create it with 'teb' (transparent
ethernet bridge).

think because you're using a TAP (L2) rather than

I don't know much about memif, but seeing as it creates an L2 device, one
avenue is adding the memif into a bridge-domain together with a transport

vpp# create bridge-domain 10
vpp# create vxlan tunnel src

Your description isn't very clear to me, unfortunately. But I think what
you're trying to do is connect an existing vlan100 interface outside of
