First setting up the Interfaces:
R1:
interfaces {
ethernet eth0 {
address 10.0.12.1/24
description R1TOR2
}
ethernet eth1 {
address 192.168.10.254/24
description LAN1
}
ethernet eth2 {
address 10.0.10.1/24
description R1TOR10
}
ethernet eth3 {
address 10.0.13.1/24
description R1TOR3
}
loopback lo {
address 1.1.1.1/32
}
R2:
interfaces {
ethernet eth0 {
address 10.0.12.2/24
description R1TOR2
}
ethernet eth1 {
address 192.168.2.254/24
description LAN2
}
loopback lo {
address 2.2.2.2/32
}
R3
interfaces {
ethernet eth0 {
address 10.0.13.3/24
description R1TOR3
speed auto
}
ethernet eth1 {
address 192.168.3.254/24
description LAN3
}
loopback lo {
address 3.3.3.3/32
}
}
Setting up the IGP:
R1:
protocols {
ospf {
area 0 {
network 10.0.12.0/24
network 10.0.13.0/24
}
area 1 {
network 1.1.1.1/32
network 192.168.10.0/24
}
area 10 {
network 10.0.10.0/24
}
parameters {
router-id 1.1.1.1
}
}
R2:
protocols {
ospf {
area 0 {
network 10.0.12.0/24
}
area 2 {
network 2.2.2.2/32
network 192.168.2.0/24
}
parameters {
router-id 2.2.2.2
}
}
}
R3:
protocols {
ospf {
area 0 {
network 10.0.13.0/24
}
area 3 {
network 192.168.3.0/24
network 3.3.3.3/32
}
}
}
Setting up the QoS Policy:
R1:
qos-policy {
traffic-shaper SITE1 {
bandwidth 125kbit
class 10 {
bandwidth 85Kbit
match VOIP-RTP {
ip {
dscp 46
}
}
}
class 20 {
bandwidth 15kbit
match VOIP-CONTROL {
ip {
protocol udp
source {
port 5060
}
}
}
}
class 30 {
bandwidth 10kbit
match OSPF {
ip {
protocol ospf
}
}
queue-type fair-queue
}
default {
bandwidth 10kbit
}
description QOS_for_SITE1
}
The applying it:
R1:
interfaces {
ethernet eth0 {
address 10.0.12.1/24
description R1TOR2
qos-policy {
out SITE1
}
Here is the video where I configure and test it:
