Testing VRRP Module
|
|
===================
|
|
|
|
This page describes how to test Ryu VRRP service
|
|
|
|
Running integrated tests
|
|
========================
|
|
|
|
Some testing scripts are available.

Running multiple Ryu VRRP in network namespace
|
|
==============================================
|
|
|
|
The following command lines set up necessary bridges and interfaces.
|
|
|
|
And then run RYU-VRRP::
|
|
|
|
# ip netns add gateway1
|
|
# ip netns add gateway2
|
|
|
|
# brctl addbr vrrp-br0
|
|
# brctl addbr vrrp-br1
|
|
|
|
# ip link add veth0 type veth peer name veth0-br0
|
|
# ip link add veth1 type veth peer name veth1-br0
|
|
# ip link add veth2 type veth peer name veth2-br0
|
|
# ip link add veth3 type veth peer name veth3-br1
|
|
# ip link add veth4 type veth peer name veth4-br1
|
|
# ip link add veth5 type veth peer name veth5-br1
|
|
|
|
# brctl addif vrrp-br0 veth0-br0
|
|
# brctl addif vrrp-br0 veth1-br0
|
|
# brctl addif vrrp-br0 veth2-br0
|
|
# brctl addif vrrp-br1 veth3-br1
|
|
# brctl addif vrrp-br1 veth4-br1
|
|
# brctl addif vrrp-br1 veth5-br1
|
|
|
|
# ip link set vrrp-br0 up
|
|
# ip link set vrrp-br1 up
|
|
|
|
# ip link set veth0 up
|
|
# ip link set veth0-br0 up
|
|
# ip link set veth1-br0 up
|
|
# ip link set veth2-br0 up
|
|
# ip link set veth3-br1 up
|
|
# ip link set veth4-br1 up
|
|
# ip link set veth5 up
|
|
# ip link set veth5-br1 up
|
|
|
|
# ip link set veth1 netns gateway1
|
|
# ip link set veth2 netns gateway2
|
|
# ip link set veth3 netns gateway1
|
|
# ip link set veth4 netns gateway2
|
|
|
|
# ip netns exec gateway1 ip link set veth1 up
|
|
# ip netns exec gateway2 ip link set veth2 up
|
|
# ip netns exec gateway1 ip link set veth3 up
|
|
# ip netns exec gateway2 ip link set veth4 up
|
|
|
|
# ip netns exec gateway1 .ryu-vrrp veth1 '10.0.0.2' 254
|
|
# ip netns exec gateway2 .ryu-vrrp veth2 '10.0.0.3' 100
|
|
|
|
|
|
.. admonition:: Caveats
|
|
|
|
Please make sure that all interfaces and bridges are UP.
|
|
Don't forget interfaces in netns gateway1/gateway2.
