Contributed by Daniel Perez Vertti Vazquez, Cisco TAC Engineer.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

- PBR configuration on  Cisco Adaptive Security Appliance (ASA)

- FlexConfig on  Firepower

- IP SLAs

Components Used

The information in this document is based on these software and hardware versions:

- Cisco FTD version 7.0.0 (Build 94)

- Cisco FMC version 7.0.0 (Build 94)

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Background Information

This document describes how to configure  Policy Based Routing (PBR)  along with  Internet Protocol Service Level Agreement (IP SLA)  on a Cisco  Firepower Threat Defense (FTD)  that is managed by Cisco Firepower Management Center (FMC).

The traditional routing takes forwarding decisions based on the destination IP addresses only. PBR is an alternative to routing protocols and static routing.

It provides more granular control over routing because it allows the use of parameters such as source IP addresses or source and destination ports as routing criteria besides the destination IP address.

Possible scenarios for PBR include source sensitive applications or traffic over dedicated links.

Along with PBR, IP SLAs can be implemented in order to ensure availability of the next hop. An IP SLA is a mechanism that monitors end to end connectivity through the exchange of regular packets.

At the time of publication, PBR is not directly supported through FMC  Graphical User Interface (GUI) , the configuration of the feature requires the use of FlexConfig policies.

On the other hand, only  Internet Control Message Protocol (ICMP)  SLAs are supported by FTD.

In this example, PBR is used to route packets over a primary  Internet Service Provider (ISP)  circuit based on the source IP address.

In the meantime, an IP SLA monitors connectivity and forces a fallback to backup circuit in case of any failure.

Configure

Network Diagram

In this example, Cisco FTD has two outside interfaces: VLAN230 and VLAN232. Each one connects to a different ISP.

The traffic from internal network VLAN2813 is routed through the primary ISP which uses PBR.

The PBR route map takes forwarding decisions based on the source IP address only (everything received from VLAN2813 must be routed to 10.88.243.1 in VLAN230) and it is applied in interface GigabitEthernet 0/1 of FTD.

In the meantime, FTD uses IP SLAs in order to monitor connectivity to each ISP Gateway. In case of any failure in VLAN230, FTD failovers to the backup circuit on VLAN232.

Configurations

Step 1. Configure PBR Access List

At the first step of PBR configuration, define which packets must be subject of the routing policy. PBR makes use of route maps and access list to identify traffic.

In order to define an access list for the matching criteria navigate to  Objects > Object Management  and select  Extended  under the  Access List  category in the table of contents.

Click  Add Extended Access List . In the  New Extended Access List Object  window, assign a name for the object, then select the  Add  button in order to start with access list configuration.

In the  Add Extended Access List Entry  window, select the object that represents the inside network, in this case VLAN2813.

Click  Add to Source  to define it as the source of the access list.

Click  Add  to create the entry.

Click  Save . The object must be added to object list.

Step 2. Configure PBR Route Map

Once the PBR access list is configured, assign it to a route map. Route map evaluates traffic against the match clauses defined in the access list.

After a match occurs, route map executes the actions defined in the routing policy.

To define route map, navigate to  Objects > Object Management  and select  Route Map  in the table of contents.

Click  Add Route Map >. In the  New Route Map Object  assign a name for the object, then click  Add  to create a new route map entry.

In the  Add Route Map Entry  window, define a sequence number for the position of the new entry.

Navigate to IPv4 > Match Clauses and select Extended in the  Available Access List drop down menu.

Select the access list object created in Step 1.

Click  Add  to create the entry.

Note: FTD supports up to 65536 (from 0 to 65535) different entries. The lower the number, the highest the priority evaluation.

Click  Save . Add the object to the object list.

Step 3. Configure FlexConfig Text Objects

The next step involves the definition of FlexConfig text objects that represent default Gateways for each circuit. These text objects are used later in the configuration of FlexConfig object that associates PBR with SLAs.

In order to define a FlexConfig text object navigate to  Objects > Object Management  and select  Text Object  under the  FlexConfig  category in the table of contents.

Click  Add Text Object  . In the  Add Text Object window, assign a name for the object that represents the primary Gateway and specify the IPv4 address for this device.

Click  Save  to add the new object.

Click  Add Text Object  again to create a second object, this time for the Gateway on the backup circuit.

Fill the new object with the appropriate name and IP address and click  Save .

The two objects must be added to the list along with the default objects.

Step 4. Configure SLA Monitor

To define the SLA objects used to monitor connectivity to each Gateway, navigate to  Objects > Object Management  and select  SLA Monitor  in the table of contents.

Select the  Add SLA Monitor  object.

In the New SLA Monitor  window, define a name along with an identifier for the SLA operation, the IP address for the device that must be monitored (in this case the primary Gateway), and the interface or zone through which the device is reachable.

Additionally, it is also possible to adjust the timeout and threshold. Click  Save .

Note: FTD supports up to 2000 SLA operations. The values for the SLA ID range from 1 to 2147483647.

Note: If timeout and threshold values are not specified, FTD uses default timers: 5000 miliseconds in each case.

Select the  Add SLA Monitor  button once more in order to create a second object, this time for the Gateway on the backup circuit.

Fill the new object with the appropriate information, ensure the SLA ID is different from the one defined for the primary Gateway, and save changes.

The two objects must be added to the list.

Step 4. Configure Static Routes with Route Track

Once the IP SLA objects are created, define a route for each Gateway and associate them to the SLAs.

These routes do not actually provide connectivity from inside to outside (all the routing is performed through PBR), instead, they are needed to track connectivity to the Gateways through SLAs.

In order to configure static routes, navigate to  Devices > Device Management , edit the FTD at hand and select  Static Route in the table of contents within the  Routing  tab.

In the  Add Static Route Configuration  window, in the Interface drop down, specify the name for the interface through which the primary Gateway must be reachable.

Then select the destination network and the primary Gateway in the  Gateway drop down.

Specify a metric for the route and in the Route Track drop down and select the SLA object for the primary gateway created in Step 3.

Click OK to add the new route.

A second static route must be configured for the backup Gateway.

Click Add Route  to define a new static route.

Fill the  Add Static Route Configuration  with the information for the backup Gateway and ensure the metric for this route is higher than the one configured in the first route.

The two routes must be added to the list.

Step 5. Configure PBR FlexConfig Object

Enable SLAs under the route map used for PBR and apply this route map in an interface of the FTD.

So far, route map has been only associated to the access list that defines the matching criteria. However, the last adjustments are not supported through FMC GUI so a FlexConfig object is needed.

To define the PBR FlexConfig object navigate to Objects > Object Management and select  FlexConfig Object  under the  FlexConfig  category in the table of contents.

Select the  Add FlexConfig Object  button. In the  Add FlexConfig Object  window assign a name and navigate to  Insert > Insert Policy Object > Route Map .

In the  Insert Route Map Variable  window, assign a name for the variable and select the PBR object created in Step 2.

Click  Save  to add the route map as part of the FlexConfig object.

Besides the route map variable, we must add the FlexConfig text objects that represent each Gateway (defined in Step 3). In the  Add FlexConfig Object  window navigate to  Insert > Insert Policy Object > Text Object .

In the  Insert Text Object Variable  window assign a name for the variable and select the text object that represents the primary Gateway defined in Step 3.

Click  Save  button in order to add it to the FlexConfig object.

Repeat these last steps for backup Gateway. At the end of the process, the two variables must be appended to the FlexConfig object.

The syntax for the PBR configuration must be the same as in Cisco ASA. The sequence number for the route map must match the one configured in Step 2 (10 in this case) as well as the SLA IDs.

To configure PBR to check availability for the next hop, the  set ip next-hop verify-availability command must be used.

Route map must be applied to the inside interface, in this case VLAN2813. Use  policy-route route-map  command under the interface configuration.

Click  Save  when configuration is completed.

The FlexConfig object must be added to the list.

Step 6. Assign PBR FlexConfig Object to FlexConfig Policy

Navigate to  Devices > FlexConfig  and edit the FlexConfig policy at hand.

Select the PBR FlexConfig object in Available FlexConfig  table of contents, save changes, and deploy changes to FTD.

Verify

After the deployment finishes, FTD must send regular ICMP echo request to the monitored devices in order to ensure reachability. In the meantime, a tracked route to the primary Gateway must be added to the routing table.
