Scep
These scenarios show how to configure the protocol SCEP to retrieve certificates from a PKI server; and then, establish a VPN site-to-site connection between two end-points.
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 1Show 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=0.745 ms --- 192.168.213.25 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.745/0.745/0.745/0.000 ms
Step 4: Ping IP address 192.168.213.25 from DUT2:
admin@DUT2$ ping 192.168.213.25 count 1 size 56 timeout 1Show 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=0.839 ms --- 192.168.213.25 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.839/0.839/0.839/0.000 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+ValidShow output
----------------------------------------------------------------------- Certificate Status NotBefore NotAfter ----------------------------------------------------------------------- CA_CERT Valid Dec 14 10:00:35 2023 GMT Dec 14 10:10:34 2053 GMT USER_CERT Valid Feb 13 16:13:30 2024 GMT Feb 12 16:13:30 2026 GMT
Step 9: Run command pki scep show CSR at DUT2 and check if output matches the following regular expressions:
CA_CERT\s+Valid USER_CERT\s+ValidShow output
----------------------------------------------------------------------- Certificate Status NotBefore NotAfter ----------------------------------------------------------------------- CA_CERT Valid Dec 14 10:00:35 2023 GMT Dec 14 10:10:34 2053 GMT USER_CERT Valid Feb 13 16:13:33 2024 GMT Feb 12 16:13:33 2026 GMT
Note
Now, the credentials are ready, so let’s configure the VPN site-to-site tunnel.
Step 10: Set the following configuration in DUT0:
set vpn ipsec auth-profile AUTH mode x509 set vpn ipsec auth-profile AUTH x509 csr CSR set vpn ipsec site-to-site peer PEER tunnel 1 esp-group ESP-POLICY set vpn ipsec site-to-site peer PEER ike-group IKE-POLICY set vpn ipsec ike-group IKE-POLICY key-exchange ikev2 set vpn ipsec ike-group IKE-POLICY lifetime 28800 set vpn ipsec ike-group IKE-POLICY proposal 1 encryption null set vpn ipsec ike-group IKE-POLICY proposal 1 hash sha1 set vpn ipsec ike-group IKE-POLICY proposal 1 dh-group 15 set vpn ipsec ike-group IKE-POLICY proposal 2 encryption aes256 set vpn ipsec ike-group IKE-POLICY proposal 2 hash sha1 set vpn ipsec ike-group IKE-POLICY proposal 2 dh-group 15 set vpn ipsec ike-group IKE-POLICY dead-peer-detection interval 60 set vpn ipsec esp-group ESP-POLICY lifetime 28800 set vpn ipsec esp-group ESP-POLICY proposal 1 encryption null set vpn ipsec esp-group ESP-POLICY proposal 1 hash sha1 set vpn ipsec esp-group ESP-POLICY proposal 1 pfs dh-group15 set vpn ipsec logging log-types any log-level 1 set vpn ipsec site-to-site peer PEER auth-profile AUTH set vpn ipsec site-to-site peer PEER local-address 8.0.0.2 set vpn ipsec site-to-site peer PEER remote 9.0.0.2 set vpn ipsec site-to-site peer PEER tunnel 1 local prefix 192.168.1.0/24 set vpn ipsec site-to-site peer PEER tunnel 1 remote prefix 192.168.2.0/24 set vpn ipsec site-to-site peer PEER connection-type respond
Step 11: Set the following configuration in DUT2:
set vpn ipsec auth-profile AUTH mode x509 set vpn ipsec auth-profile AUTH x509 csr CSR set vpn ipsec site-to-site peer PEER tunnel 1 esp-group ESP-POLICY set vpn ipsec site-to-site peer PEER ike-group IKE-POLICY set vpn ipsec ike-group IKE-POLICY key-exchange ikev2 set vpn ipsec ike-group IKE-POLICY lifetime 28800 set vpn ipsec ike-group IKE-POLICY proposal 1 encryption null set vpn ipsec ike-group IKE-POLICY proposal 1 hash sha1 set vpn ipsec ike-group IKE-POLICY proposal 1 dh-group 15 set vpn ipsec ike-group IKE-POLICY proposal 2 encryption aes256 set vpn ipsec ike-group IKE-POLICY proposal 2 hash sha1 set vpn ipsec ike-group IKE-POLICY proposal 2 dh-group 15 set vpn ipsec ike-group IKE-POLICY dead-peer-detection interval 60 set vpn ipsec esp-group ESP-POLICY lifetime 28800 set vpn ipsec esp-group ESP-POLICY proposal 1 encryption null set vpn ipsec esp-group ESP-POLICY proposal 1 hash sha1 set vpn ipsec esp-group ESP-POLICY proposal 1 pfs dh-group15 set vpn ipsec logging log-types any log-level 1 set vpn ipsec site-to-site peer PEER auth-profile AUTH set vpn ipsec site-to-site peer PEER local-address 9.0.0.2 set vpn ipsec site-to-site peer PEER remote 8.0.0.2 set vpn ipsec site-to-site peer PEER tunnel 1 local prefix 192.168.2.0/24 set vpn ipsec site-to-site peer PEER tunnel 1 remote prefix 192.168.1.0/24 set vpn ipsec site-to-site peer PEER connection-type initiate
Step 12: Run command vpn ipsec show sa at DUT0 and check if output matches the following regular expressions:

----------------------------------------------- Certificate Status NotBefore NotAfter ----------------------------------------------- CA_CERT Uninitialized USER_CERT Uninitialized
Note
The credentials will not be downloaded because the port for the connection to PKI server is configured wrong on purpose. Once the credentials are ready, the VPN should be established automatically.
