From operational mode, enter the show security nat source rule all command. In the Translation hits field, verify whether there is traffic that matches the source NAT rule. The support for multicast traffic is available when the security device is operating with forwarding option set as as flow-based in the set security forwarding-options family mpls mode hierarchy. See forwarding-options Security.

Flow Management Using VRF Routing Instance An SRX Series device flow creates sessions based on 5-tuple data source IP address, destination IP address, source port number, destination port number, and protocol number along with interface tokens of input interface and output interface of traffic.
You can use the following matching criteria along with existing 5-tuple matching conditions in a security policy to permit or deny traffic based on given VRF: Source VRF—This is the VRF routing instance associated with the incoming interface of the packet. Figure Note: If the traffic is initiated in the opposite direction, the VRF groups switch roles with respect to the direction of the traffic.
VRF Movement From Figure 3 , the initial traffic flow for a session establishment is from left to right. Assign a name to the VRF group. It cannot be a part of multiple VRF groups.
Overview In Junos OS, security policies enforce rules for transit traffic, in terms of what traffic can pass through the device and the actions that need to take place on the traffic as it passes through the device. Configuration Procedure CLI Quick Configuration Step-by-Step Procedure Results CLI Quick Configuration To quickly configure this example, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, copy and paste the commands into the CLI at the [edit] hierarchy level, and then enter commit from configuration mode.

See the appropriate chapter for information on how to configure VRFs for the routing protocol. This section uses OSPFv2 as an example protocol for the detailed configuration steps.
Optional maximum-paths paths. Creates a new OSPFv2 instance with the configured instance tag. Used for load balancing. Assigns this interface to the OSPFv2 instance and area configured. You can configure a VRF-aware servic e for reachability and filtering.
Use the filter-vrf keyword to filter information from the selected VRF to this server. Sets the routing context for all EXEC commands. Default routing context is the default VRF. To display VRF configuratio n information, perform one of the following tasks:.
For additional information related to implementing virtualization, see the following sections:.

The mgmt 0 interface cannot be assigned to another VRF.
No routing protocols can run in the management VRF static only. VRF lite is generally used in the office LAN or data center environment to virtualize various security zones and network elements.
There are several key terms to define in the context of virtual routing and forwarding, and a few comparisons to make, because they answer common questions. Here they are:. A virtual private network referred to as VPN is a network that provides private services over a public infrastructure. Sets of sites that privately communicate together over other private or public networks over the internet are virtual private networks VPNs. Virtual routing and forwarding or VRF configurations enable multiple VPN environments to simultaneously co-exist in a router on the same physical network or infrastructure.
This allows an organization to have segregated network services that reside in the same physical infrastructure invisible to each other—such as wireless, voice VoIP , data, and video.
You should add the mgmt0 interface to the management VRF and configure the mgmt0 IP address and other parameters after you add it to the management VRF. You should make the mgmt0 interface a member of the management VRF.
The write erase boot command does not remove the management VRF configurations. You must use the write erase command and then the write erase boot command. You can restrict route leaking to specific routes using route map filters to match designated IP addresses. There is no limit on the number of routes that can be leaked between two non-default VRFs.
Optional show vrf [ vrf-name ] 5. Step 5 copy running-config startup-config Example: switch config copy running-config startup-config Optional Saves this configuration change. T o delete the VRF and the associated configuration, use the following command in global configuration mode: Command Purpose no vrf context name Example: switch config no vrf context Enterprise Deletes the VRF and all associated configurations.
This example shows how to create a VRF and add a static route to the VRF: switch configure terminal switch config vrf context Enterprise switch config-vrf ip route Optional show vrf vrf-name interface interface-type number 6. Step 6 copy running-config startup-config Example: switch config copy running-config startup-config Optional Saves this configuration change. Optional maximum-paths paths 5. Step 2 router ospf instance-tag Example: switch config-vrf router ospf switch config-router Creates a new OSPFv2 instance with the configured instance tag.
Step 4 maximum-paths paths Example: switch config-router-vrf maximum-paths 4 Optional Configures the maximum number of equal OSPFv2 paths to a destination in the route table for this VRF. Step 8 ip router ospf instance-tag area area-id Example: switch config-if ip router ospf area 0 Assigns this interface to the OSPFv2 instance and area configured.
Step 9 copy running-config startup-config Example: switch config copy running-config startup-config Optional Saves this configuration change. Optional show bgp process vrf [ vrf-name ] 6.
Step 2 vrf context vrf-name Example: switch config vrf context vpn1 switch config-vrf Creates a new VRF. The range is from 1 to , and the default value is Step 5 show bgp process vrf [vrf-name] Example: switch config-vrf-af-ipv4 show bgp process vrf vpn1 Optional Displays the BGP process information for the specified VRF.
Step 2 snmp-server host ip-address [ filter-vrf vrf-name ] [ use-vrf vrf-name ] Example: switch config snmp-server host Step 4 ip domain-list domain-name [ all-vrfs ][ use-vrf vrf-name ] Example: switch config-vrf ip domain-list List all-vrfs use-vrf Blue switch config-vrf Configures the domain list in the VRF and optionally configures the VRF that Cisco NX-OS uses to reach the domain name listed.
