One of the nice things about network namespaces is that they allow one
to easily create and test complex environments.
Unfortunately, these namespaces can not be used with actual switching
ASICs, as their ports can not be migrated to other network namespaces
(NETIF_F_NETNS_LOCAL) and most of them probably do not support the
L1-separation provided by namespaces.
However, a similar kind of flexibility can be achieved by using VRFs and
by looping the switch ports together. For example:
br0
+
vrf-h1 | vrf-h2
+ +---+----+ +
| | | |
192.0.2.1/24 + + + + 192.0.2.2/24
swp1 swp2 swp3 swp4
+ + + +
| | | |
+--------+ +--------+
The VRFs act as lightweight namespaces representing hosts connected to
the switch.
This approach for testing switch ASICs has several advantages over the
traditional method that requires multiple physical machines, to name a
few:
1. Only the device under test (DUT) is being tested without noise from
other system.
2. Ability to easily provision complex topologies. Testing bridging
between 4-ports LAGs or 8-way ECMP requires many physical links that are
not always available. With the VRF-based approach one merely needs to
loopback more ports.
These tests are written with switch ASICs in mind, but they can be run
on any Linux box using veth pairs to emulate physical loopbacks.
v2:
* Order local variables declaration according to function arguments
order (Petr)
v1:
* Change location to net/forwarding instead of forwarding/
* Add ability to pause on failure
* Add ability to pause on cleanup
* Make configuration file optional
* Make ping/ping6/mz configurable
* Add more tc tests

Add initial framework to test packet forwarding functionality. The tests
can run on actual devices using loop-backed cables or using veth pairs.

+Motivation
+==========
+
+One of the nice things about network namespaces is that they allow one
+to easily create and test complex environments.
+
+Unfortunately, these namespaces can not be used with actual switching
+ASICs, as their ports can not be migrated to other network namespaces
+(NETIF_F_NETNS_LOCAL) and most of them probably do not support the
+L1-separation provided by namespaces.
+
+However, a similar kind of flexibility can be achieved by using VRFs and
+by looping the switch ports together. For example:
+
+ br0
+ +
+ vrf-h1 | vrf-h2
+ + +---+----+ +
+ | | | |
+ 192.0.2.1/24 + + + + 192.0.2.2/24
+ swp1 swp2 swp3 swp4
+ + + + +
+ | | | |
+ +--------+ +--------+
+
+The VRFs act as lightweight namespaces representing hosts connected to
+the switch.
+
+This approach for testing switch ASICs has several advantages over the
+traditional method that requires multiple physical machines, to name a
+few:
+
+1. Only the device under test (DUT) is being tested without noise from
+other system.
+
+2. Ability to easily provision complex topologies. Testing bridging
+between 4-ports LAGs or 8-way ECMP requires many physical links that are
+not always available. With the VRF-based approach one merely needs to
+loopback more ports.
+
+These tests are written with switch ASICs in mind, but they can be run
+on any Linux box using veth pairs to emulate physical loopbacks.
+
+Guidelines for Writing Tests
+============================
+
+o Where possible, reuse an existing topology for different tests instead
+ of recreating the same topology.
+o Where possible, IPv6 and IPv4 addresses shall conform to RFC 3849 and
+ RFC 5737, respectively.
+o Where possible, tests shall be written so that they can be reused by
+ multiple topologies and added to lib.sh.
+o Checks shall be added to lib.sh for any external dependencies.
+o Code shall be checked using ShellCheck [1] prior to submission.
+

Add initial framework to test packet forwarding functionality. The tests
can run on actual devices using loop-backed cables or using veth pairs.

+Motivation
+==========
+
+One of the nice things about network namespaces is that they allow one
+to easily create and test complex environments.
+
+Unfortunately, these namespaces can not be used with actual switching
+ASICs, as their ports can not be migrated to other network namespaces
+(NETIF_F_NETNS_LOCAL) and most of them probably do not support the
+L1-separation provided by namespaces.
+
+However, a similar kind of flexibility can be achieved by using VRFs and
+by looping the switch ports together. For example:
+
+ br0
+ +
+ vrf-h1 | vrf-h2
+ + +---+----+ +
+ | | | |
+ 192.0.2.1/24 + + + + 192.0.2.2/24
+ swp1 swp2 swp3 swp4
+ + + + +
+ | | | |
+ +--------+ +--------+
+
+The VRFs act as lightweight namespaces representing hosts connected to
+the switch.
+
+This approach for testing switch ASICs has several advantages over the
+traditional method that requires multiple physical machines, to name a
+few:
+
+1. Only the device under test (DUT) is being tested without noise from
+other system.
+
+2. Ability to easily provision complex topologies. Testing bridging
+between 4-ports LAGs or 8-way ECMP requires many physical links that are
+not always available. With the VRF-based approach one merely needs to
+loopback more ports.
+
+These tests are written with switch ASICs in mind, but they can be run
+on any Linux box using veth pairs to emulate physical loopbacks.
+
+Guidelines for Writing Tests
+============================
+
+o Where possible, reuse an existing topology for different tests instead
+ of recreating the same topology.
+o Where possible, IPv6 and IPv4 addresses shall conform to RFC 3849 and
+ RFC 5737, respectively.
+o Where possible, tests shall be written so that they can be reused by
+ multiple topologies and added to lib.sh.
+o Checks shall be added to lib.sh for any external dependencies.
+o Code shall be checked using ShellCheck [1] prior to submission.

Add test cases for unknown unicast and unregistered multicast flooding.
For each traffic type, turn off flooding on one bridged port and inject
a packet of the specified type through the second bridged port. Make
sure the packet was not received by checking the ACL counters on the
other end. Later, turn on flooding and make sure the packet was
received.

Configure two hosts which are directly connected to the same router and
test IPv4 and IPv6 ping. Use a large MTU and check that ping is
unaffected.

Create a topology with two hosts, each directly connected to a different
router. Both routers are connected using two links, enabling multipath
routing.
Test IPv4 and IPv6 ping using default MTU and large MTU.

I love this series on so many levels.
First and foremost, we now have more tests! We always need more tests!
Second, this is yet another interesting and practical use for one of
the most underutilized and most powerful facilities we have, VRF.
Whatever problems or limitations these tests have can be easily fixed
with follow-on changes.
Series applied, thanks a lot!
