Problem description You can define your own rules to route data packets, not just the destination address. Here You can learn how to use policy-based routing to solve this problem. In specific applications, policy-based routes include: ☆Source IP address-

Note: PBR was previously a major tool used by Cisco to discard messages. For example, set interface null 0, which, according to Cisco, would save a bit more overhead than the ACL's deny. Here I remind: Interface NULL 0No IP unreachable//Join this commandThis avoids the return of many ICMP unreachable messages because of the large number of packets discarded. When a three-tier device forwards a packet

network address. It is found that the traffic of hosts in different network segments has indeed accessed external resources from different egress, and different Nat addresses are used for address translation! Note: The NAT address translation function is required for most ISP scenarios. However, in some special cases, the NAT Function is not required. If the NAT Function is not used, remove the NAT configuration in the configuration, Remove ip nat inside source list 1 interface FastEthernet0/0

policy-based Routing (PBR) is a flexible packet routing and forwarding mechanism. By applying the policy route on the router, the router determines how the router's packets are handled based on the

matches a datagram successfully? The standard action of the routing software is generally to select the next hop address and the output interface, which can be called a "Match set" action. However, Linux adopts a more flexible approach, and there are multiple actions available in Linux. The default action is to query a specific route table based on the destinat
