Specific set up equipment before testing
MX204#1 uses breakout cable on FPC 0 PIC 0 port 3 for testing purpose.
Due to the lack of servers we need to make some additional settings on the HCoS#2 server itself to isolate 2 ports belonging to different logical servers (HCoS#2-D and HCoS#2-B) in order to achieve that the traffic from the first server passes through both MX204 routers and reaches another server. We added some lines in the following files:
/etc/network/interfaces file
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto em1
iface em1 inet static
address 10.1.1.22
netmask 255.255.255.0
network 10.1.1.0
broadcast 10.1.1.255
gateway 10.1.1.1
# dns-* options are implemented by the resolvconf package, if installed
dns-nameservers 8.8.8.8
up ip netns add isolated
up ip link set dev p4p2 netns isolated
up ip netns exec isolated ip addr add 192.168.2.1/24 dev p4p2
up ip netns exec isolated ip link set p4p2 up
#auto p4p2
#iface p4p2 inet static
# address 192.168.2.1
# netmask 255.255.255.0
auto p4p1.10
iface p4p1.10 inet static
address 192.168.0.2
netmask 255.255.255.0
vlan-raw-device p4p1
auto p4p1.20
iface p4p1.20 inet static
address 192.168.1.2
netmask 255.255.255.0
vlan-raw-device p4p1
auto p4p1.30
iface p4p1.30 inet static
address 192.168.2.2
netmask 255.255.255.0
vlan-raw-device p4p1
In this file we added seperated name space called isolated in which we put p4p2 interface. In order to have any action with that interface it is necessary to type ip netns exec isolated before any known command.For example, to see configuration on that interface we need to type the following:
ip netns exec isolated ifconfig
root@HQoS2:/home/taas# ip netns exec isolated ifconfig

/etc/modules file

In this file we added 8021q in order to support tagging.
