What is policy-based routing Cisco?

What is policy-based routing Cisco?

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.

What benefits does policy-based routing provide?

Policy-based routing (PBR) provides network administrators with agility and flexibility to better manage traffic. With carefully architected policies, you can optimize how segments of your network process data, as well as how bandwidth is managed for business-critical applications.

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. All packets received on an interface with local policy-based routing are configured in route maps.

What is route based and policy-based VPN?

In a policy-based VPN configuration, the action must be permit and must include a tunnel. Route-based VPNs support the exchange of dynamic routing information through VPN tunnels. You can enable an instance of a dynamic routing protocol, such as OSPF, on an st0 interface that is bound to a VPN tunnel.

What is source based routing?

Source-based routing selects which gateway to direct outgoing client traffic through based on the source IP address in each packet header. When enabled, source-based routing automatically scans your network configuration to create client traffic rules.

What is IP source route Cisco?

IP source-route is a little-used option that allows the originator of a packet to decide which routers he should go through to get to his destination. He does this by supplying the full path of routers on the options header of the IP packet.

Does Cisco ASA support PBR?

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. Finally Cisco acknowledged the usefulness of PBR on firewall devices and has implemented this on ASA as well.

Can route based VPN connect to policy based VPN?

Route-based VPNs support NAT for st0 interfaces. Policy-based VPNs cannot be used if NAT is required for tunneled traffic. Proxy ID is supported for both route-based and policy-based VPNs. Route-based tunnels also offer the usage of multiple traffic selectors also known as multi-proxy ID.

Is Palo Alto route-based or policy-based?

Palo Alto Network firewalls do not support policy-based VPNs. The policy-based VPNs have specific security rules/policies or access-lists (source addresses, destination addresses and ports) configured for permitting the interesting traffic through IPSec tunnels.
