Address Group

The following scenario shows how to configure a traffic group with different IPv4 addresses. traffic selectors can be configured to filter network packets based on their source / destination address.

Test Traffic Group With IPv4 Addresses

Description

In this scenario, an ingress traffic policy is configured to deny non-matching packets in DUT0 (‘eth0’ interface). Packets are filtered using a traffic selector and a traffic group.

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth0 address 10.0.0.1/24
set interfaces ethernet eth0 traffic policy in ACCEPT_ALLOWED
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set traffic group address ALLOWED element 10.0.0.2-10.0.0.9
set traffic group address ALLOWED element 10.0.0.254
set traffic policy ACCEPT_ALLOWED rule 1 action accept
set traffic policy ACCEPT_ALLOWED rule 1 selector SEL_ALLOWED
set traffic policy ACCEPT_ALLOWED rule 2 action drop
set traffic selector SEL_ALLOWED rule 1 source address-group ALLOWED

Step 2: Set the following configuration in DUT1:

set interfaces ethernet eth0 address 10.0.0.2/24
set interfaces ethernet eth0 vrf A
set interfaces ethernet eth1 address 10.0.0.20/24
set interfaces ethernet eth1 vrf B
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
set system vrf A
set system vrf B

Step 3: Ping IP address 10.0.0.1 from DUT1:

admin@DUT1$ ping 10.0.0.1 vrf A count 1 size 56 timeout 1

Show output

ping: Warning: source address might be selected on device other than: A
PING 10.0.0.1 (10.0.0.1) from 10.0.0.2 A: 56(84) bytes of data.
64 bytes from 10.0.0.1: icmp_seq=1 ttl=64 time=0.283 ms

--- 10.0.0.1 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.283/0.283/0.283/0.000 ms

Step 4: Initiate a tcp connection from DUT1 to DUT0 and try to send some messages between both endpoints

admin@DUT0$ monitor test connection server 8080 tcp
admin@DUT1$ monitor test connection client 10.0.0.1 8080 tcp local-interface eth0

Step 5: Expect a failure in the following command: Initiate a tcp connection from DUT1 to DUT0 and try to send some messages between both endpoints

admin@DUT0$ monitor test connection server 8080 tcp
admin@DUT1$ monitor test connection client 10.0.0.1 8080 tcp local-interface eth1
