Does ASA support policy based routing?
This post describes how to configure a Cisco ASA firewall to support Policy Based Routing (PBR). PBR allows an administrator to define routing based on source address, source port, destination address, destination port, protocol or a combination of all these.
What is policy based routing Cisco?
Policy-based routing is a process whereby the device puts packets through a route map before routing them. To enable policy-based routing on an interface, indicate which route map the device should use by using the ip policy route-map map-tag command in interface configuration mode.
What is policy based routing used for?
When to Use Policy-Based Routing? Policy-based routing is ideal for overriding the default behavior of a routing table. When default protocols or metrics send packets through an inefficient or just undesirable path, PBR lets us divert traffic to a route that’s more desirable.
How do I set up policy based routing?
How to Configure PBR (Policy-Based Routing)?
- Step1: Configure ACLs. Permit statement in ACL is what will be matched.
- Step2: Configure route map instances.
- Step3: Configure match commands.
- Step4: Configure set commands.
- Step5: Configure PBR on the interface.
- Step6: (Optional) Configure local PBR.
How do I set policy based routing on Cisco FTD?
Access List
- Navigate to Objects > Object Management > Access List > Extended.
- Click Add Extended Access List.
- Name the ACL appropriately, i.e., PBR-OUTSIDE-2.
- Click Add.
- Set the Action as Allow.
- Set the Source Networks as the network object(s) previously created.
- Select any4 as the Destination Network.
- Click Save.
How do I set up policy-based routing?
What is policy-based routing FortiGate?
Policy routing allows you to specify an interface to route traffic. This is useful when you need to route certain types of network traffic differently than you would if you were using the routing table.
What is local policy-based routing?
Local policy-based routing allows you to configure a defined policy for IPv6 traffic flows, lessening reliance on routes derived from routing protocols. The route maps dictate the policy, determining where to forward packets. Route maps are composed of match and set statements that you can mark as permit or deny.
What Cannot you do with policy-based routing?
Limitations of PBR One issue with PBR is that it is like a static route in that it is locally significant. If you need to have policy applied on multiple routers in a path between devices, PBR would have to be configured hop by hop.
Does Asa 5506-x support policy based routing?
Cisco ASA 9.4 (and later) is now supporting Policy Based Routing. Yeah. Great news, since many customers are requesting something like “HTTP traffic to the left – VoIP traffic to the right”. Coming with a new Cisco ASA 5506-X I was happy to try the policy based routing feature.
How does policy routing work in ASA?
Since the ASA performs routing on a per-flow basis, policy routing is applied on the first packet and the resulting routing decision is stored in the flow created for the packet. All subsequent packets belonging to the same connection simply match this flow and are routed appropriately.
What is PBR configuration in Cisco ASA?
Cisco ASA Policy Based Routing (PBR) Configuration. Policy Based Routing (PBR) is a feature that has been supported on Cisco Routers for ages. However, Cisco ASA firewalls didn’t support this until version 9.4.1 and later.
What is equal-access source sensitive routing (Asa)?
As an example, in the topology depicted in the Equal-Access Source Sensitive Routing scenario, an administrator can configure policy based routing to load share the traffic from HR network through ISP1 and traffic from Eng network through ISP2. The ASA uses ACLs to match traffic and then perform routing actions on the traffic.
