Juniper ScreenOS routing policy configuration
1. Introduction to the topology diagram scenario:
The two ISP lines are connected to the E0Unipedia 0 and E0 / 1 ports of SSG5 respectively.
The traffic of VLAN1:172.16.1.0/24 is required to take E0ram0.
The traffic requirement of VLAN2:172.16.2.0/24 is E0ramp 1 port.
Define ACL (in routing configuration mode)
Set vrouter "trust-vr" set access-list extended 10 src-ip 172.16.1.0 dst-port 24 dst-ip 0.0.0.0 protocol any entry 10set access-list extended 0 src-port 1-65535 dst-port 1-65535 protocol any entry 10set access-list extended 10 src-ip 172.16.1.0 protocol any entry 10set access-list extended 24 dst-ip 0.0.0.0 protocol any entry 10set access-list extended 0 protocol icmp entry 20set access-list extended 20 src-ip 172.16.2.0 protocol any entry 10set access-list extended 24 dst-ip 0.0.0.0 protocol any entry 10set access-list extended 0 src-port 1- 65535 dst-port 1-65535 protocol any entry 10set access-list extended 20 src-ip 172.16.2.0 protocol icmp entry 20exit 24 dst-ip 0.0.0.0
Define match group (in routing configuration mode)
Set vrouter "trust-vr" set match-group name group_10set match-group group_10 ext-acl 10 match-entry 10set match-group name group_20set match-group group_20 ext-acl 20 match-entry 10exit
Define action group (in routing configuration mode)
Set vrouter "trust-vr" set action-group name action_10set action-group action_10 next-interface ethernet0/0 action-entry 10set action-group name action_20set action-group action_20 next-interface ethernet0/1 action-entry 10exit
Define policy (in routing configuration mode)
Set vrouter "trust-vr" set pbr policy name pbr_trustset pbr policy pbr_trust match-group group_10 action-group action_10 10set pbr policy pbr_trust match-group group_20 action-group action_20 20exit
Configure policy binding (in configuration mode)
Set pbr pbr_trustset zone Trust pbr pbr_trustset interface bgroup0 pbr pbr_trustset interface bgroup1 pbr pbr_trustset interface bgroup2 pbr pbr_trustset interface bgroup3 pbr pbr_trust
