Create veth interfaces on host
|
||
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
In Linux, there is a type of interface call 'veth'. Think of a 'veth'
|
||
|
|
interface as being an interface that has two ends to it (rather than
|
||
|
|
one).
|
||
|
|
|
||
|
|
Create a veth interface with one end named **vpp1out** and the other
|
||
|
|
named **vpp1host**
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ sudo ip link add name vpp1out type veth peer name vpp1host
|
||
|
|
|
||
|
|
Turn up both ends:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ sudo ip link set dev vpp1out up
|
||
|
|
$ sudo ip link set dev vpp1host up
|
||
|
|
|
||
|
|
Assign an IP address
|
||
|
|
~~~~~~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ sudo ip addr add 10.10.1.1/24 dev vpp1host
|
||
|
|
|
||
|
|
Display the result:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
$ sudo ip addr show vpp1host
|
||
|
|
5: vpp1host@vpp1out: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
|
||
|
|
link/ether e2:0f:1e:59:ec:f7 brd ff:ff:ff:ff:ff:ff
|
||
|
|
inet 10.10.1.1/24 scope global vpp1host
|
||
|
|
valid_lft forever preferred_lft forever
|
||
|
|
inet6 fe80::e00f:1eff:fe59:ecf7/64 scope link

|
||
|
|
Create vpp host-interface
|
||
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
Create a host interface attached to **vpp1out**.
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
vpp# create host-interface name vpp1out
|
||
|
|
host-vpp1out
|
||
|
|
|
||
|
|
Confirm the interface:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
vpp# show hardware
|
||
|
|
Name Idx Link Hardware
|
||
|
|
host-vpp1out 1 up host-vpp1out
|
||
|
|
Ethernet address 02:fe:d9:75:d5:b4
|
||
|
|
Linux PACKET socket interface
|
||
|
|
local0 0 down local0
|
||
|
|
local
|
||
|
|
|
||
|
|
Turn up the interface:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
vpp# set int state host-vpp1out up
|
||
|
|
|
||
|
|
Confirm the interface is up:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
vpp# show int
|
||
|
|
Name Idx State MTU (L3/IP4/IP6/MPLS) Counter Count
|
||
|
|
host-vpp1out 1 up 9000/0/0/0
|
||
|
|
local0 0 down 0/0/0/0
|
||
|
|
|
||
|
|
Assign ip address 10.10.1.2/24
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
vpp# set int ip address host-vpp1out 10.10.1.2/24
|
||
|
|
|
||
|
|
Confirm the ip address is assigned:
|
||
|
|
|
||
|
|
.. code-block:: console
|
||
|
|
|
||
|
|
vpp# show int addr
|
||
|
|
host-vpp1out (up):
|
||
|
|
L3 10.10.1.2/24
|
||
|
|
local0 (dn):
|
