Hello, I'm working on SPDK library + VPP, because some report said that VPP
reduces the overhead of network. When I test with VPP (with mlx5 poll mode
driver mtu 9000) and null device with spdk, 4k performance with VPP is much
better than the default(kTCP). But, 128k write performance with VPP
Hi all,
I have two interfaces (wan0 and wan1) with two different IP addresses.
vpp config:
set int state wan0 up
set int state wan1 up
set int state lan1 up
set int ip address wan0 10.100.1.5/29
ip route add 0.0.0.0/0 via 10.100.1.8
loopback create
set int l2 bridge loop0 1 bvi
set int ip
The MAC address ad:ef:ad:ef:de:ad is a multicast address. That’s why packet
with that destination MAC is flooded in the bridge. Try assign a unicast MAC
address to gtpu_tunnel1.
Regards,
John

Hi All,
I request your help on L2 Bridge in VPP. I wanted to know if we can selectively
forward L2 packets
to different interfaces on a bridge based on the ethernet address.
For e.g there is one interface and 2 GTPU tunnels on a L2 bridge.
I have added an entry into the L2 Fib table telling
Hello VPP developers,
We have a problem with VPP used for NAT on Ubuntu 18.04 servers

VPP is dropping packets in the ip4-input node due to "ip4

Hi Neale and Dave,

On the sending side, to make it send multicast packets:
adj_index_t adj_index_for_multicast =
you need to set it on both sides:
For VPP:
$ ccmake build-root/build-vpp-native/vpp
and change PRE_DATA_SIZE to 256
or modify following line:
src/vlib/CMakeLists.txt:
set(PRE_DATA_SIZE 128 CACHE STRING "Buffer headroom size.”)
For DPDK you should be able to build custom ext deps package:

Hi folks,
In FD.io vpp the default VLIB_BUFFER_PRE_DATA_SIZE data header room size is
defined as 128.
And in dpdk also it is defined as 128 as we have encapsulation which goes
beyond 128 bytes
the packet descriptor block is getting corrupted in the structure
vlib_buffer_t as defined in
12 matches
