What is Cisco Policy-Based Routing?

The Policy-Based Routing feature is a process whereby a device puts packets through a route map before routing the packets. The route map determines which packets are routed next to which device. Policy-based routing is a more flexible mechanism for routing packets than destination routing.

How do I configure Cisco Policy-Based Routing?

PBR on Cisco router can configure using following steps:

1. Step1: Configure ACLs. Permit statement in ACL is what will be matched.
2. Step2: Configure route map instances.
3. Step3: Configure match commands.
4. Step4: Configure set commands.
5. Step5: Configure PBR on the interface.
6. Step6: (Optional) Configure local PBR.

What is Policy-Based Routing firewall?

Policy-based routing (PBR) is a technique that forwards and routes data packets based on policies or filters. The goal of PBR is to make the network as agile as possible. By defining routing behavior based on application attributes, PBR provides flexible, granular traffic-handling capabilities for forwarding packets.

How do I enable policy based routing?

How to Configure Policy-Based Routing

1. enable.
2. configure terminal.
3. interface type number.
4. ip policy route-map map-tag.
5. exit.
6. route-map map-tag [permit | deny ] [ sequence-number ] [
7. Enter one or both of the following commands:
8. set ip next-hop { ip-address […

What is policy based routing used for?

Policy-based routing provides a tool for forwarding and routing data packets based on policies defined by network administrators. In effect, it is a way to have the policy override routing protocol decisions.

What is IP policy route map?

Policy-based routing (PBR) is a process whereby the device puts packets through a route map before routing them. The route map determines which packets are routed to which device next. This ip policy route-map command disables fast switching of all packets arriving on this interface.

What routing is policy based?

Policy-based routing (PBR) is a process whereby the device puts packets through a route map before routing them. The route map determines which packets are routed to which device next. You might enable policy-based routing if you want certain packets to be routed some way other than the obvious shortest path.

How do you do policy-based routing?

Can a ACL be used in policy based routing?

An ACL used in a policy-based routing route map cannot include deny access control entries (ACEs). Policy-based routing is supported only in the default system routing mode. The Cisco Nexus 9000 Series switches do not support the set vrf and set default next-hop commands.

How to disable policy based routing in Cisco?

Use the no form of this command to disable the policy-based routing feature. Note The no feature pbr command removes the policies applied under the interfaces. It does not remove the ACL or route-map configuration nor does it create a system checkpoint. (Optional) Displays enabled and disabled features.

How is PBR ( policy-based routing ) used in routing?

By using PBR, customers can implement policies that selectively cause packets to take different paths. Traditional IP routing forwards packets based only on the destination IP address in the packet. PBR can be configured to forward packets based on other criteria, such as source address, application and the length of the packet.

What do I need to know about Cisco Nexus 9000 routing?

Matches an IPv4 or IPv6 address against one or more IP or IPv6 access control lists (ACLs). This command is used for policy-based routing and is ignored by route filtering or redistribution. (Optional) Sets the IPv4 next-hop address for policy-based routing.
