Test SCEP Credentials Ready

Description

In this scenario, the credentials (X509 certificates) are retrieved before VPN settings are configured.

Scenario

Step 1: Set the following configuration in DUT0:

set interfaces ethernet eth1 address 10.215.168.64/24
set interfaces ethernet eth1 tcp-mss 1200
set protocols static route 192.168.212.0/22 next-hop 10.215.168.1

Step 2: Set the following configuration in DUT2:

set interfaces ethernet eth1 address 10.215.168.66/24
set interfaces ethernet eth1 tcp-mss 1200
set protocols static route 192.168.212.0/22 next-hop 10.215.168.1

Step 3: Ping IP address 192.168.213.25 from DUT0:

admin@DUT0$ ping 192.168.213.25 count 1 size 56 timeout 1
Show output
PING 192.168.213.25 (192.168.213.25) 56(84) bytes of data.
64 bytes from 192.168.213.25: icmp_seq=1 ttl=126 time=1.09 ms

--- 192.168.213.25 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 1.086/1.086/1.086/0.000 ms

Step 4: Ping IP address 192.168.213.25 from DUT2:

admin@DUT2$ ping 192.168.213.25 count 1 size 56 timeout 1
Show output
PING 192.168.213.25 (192.168.213.25) 56(84) bytes of data.
64 bytes from 192.168.213.25: icmp_seq=1 ttl=126 time=0.857 ms

--- 192.168.213.25 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.857/0.857/0.857/0.000 ms

Step 5: Set the following configuration in DUT0:

set interfaces ethernet eth1 tcp-mss 1200
set interfaces dummy dum0 address 192.168.1.1/24
set interfaces ethernet eth0 address 8.0.0.2/24
set system certificate scep csr CSR distinguished-names 'DC=scep, DC=com, CN=entity1'
set protocols static route 0.0.0.0/0 next-hop 8.0.0.1
set system certificate scep csr CSR cgi-path CertSrv/mscep/mscep.dll/pkiclient.exe
set system certificate scep csr CSR challenge-password 8287796B080BB7573AD2C751E374FF64
set system certificate scep csr CSR url http://192.168.213.25/

Step 6: Set the following configuration in DUT1:

set interfaces ethernet eth0 address 8.0.0.1/24
set interfaces ethernet eth1 address 9.0.0.1/24

Step 7: Set the following configuration in DUT2:

set interfaces ethernet eth1 tcp-mss 1200
set interfaces dummy dum0 address 192.168.2.1/24
set interfaces ethernet eth0 address 9.0.0.2/24
set system certificate scep csr CSR distinguished-names 'DC=scep, DC=com, CN=entity2'
set protocols static route 0.0.0.0/0 next-hop 9.0.0.1
set system certificate scep csr CSR cgi-path CertSrv/mscep/mscep.dll/pkiclient.exe
set system certificate scep csr CSR challenge-password 8287796B080BB7573AD2C751E374FF64
set system certificate scep csr CSR url http://192.168.213.25/

Step 8: Run command pki scep show CSR at DUT0 and check if output matches the following regular expressions:

CA_CERT\s+Valid
USER_CERT\s+Valid
Show output
-----------------------------------------------------------------------
Certificate  Status         NotBefore                  NotAfter
