Packet Flow From Switch To Router

In case any of the above mentioned points are true the packet gets forwarded to the switch cpu port.

Packet flow from switch to router.

Thanks for the series i wish to know how the packet flow between two switches with one host 192 168 1 1 24 in one switch and another host 192 168 1 5 24 in another switch. Ip packet s flow across the network. I am going to map each step to the upper large figure so i recommend to print or open it in different window to map each step. In flow mode srx processes all traffic by analyzing the state or session of traffic.

All the routers in these detailed steps are using ospfv2 routing protocol already configured with routes and subnets. If not packet dropped with icmp time exceeded 11. Run a packet through the switch host table to make a forwarding decision. The functions of a router switch and hub and are all different even if at times they are integrated into a single device.

Else the packet has to be routed. An srx device can operate in two different modes. The packet exits through the switch cpu port and it will be further processed by the routeros packet flow. Here s the network we are going to be playing with today.

Can you please explain this for me. This is also called stateful processing of traffic. The biggest thing to keep in the back of your mind is two things. We re going to look at a couple of things here.

Host d will reject the request and the host b will accept it and generates an arp reply for the mac address 000b be8e 5202 router fa0 1 mac address because the arp reply has to be given to that mac address from which arp request has been recieved. Checks the ttl value is 1. In packet mode srx processes the traffic as a traditional router on a per packet basis. The router use the next hop ip and interfaces to be used to build the new data link frame 13.

The packet is received by the switch which in turn broadcast the request to host b and d. Routers connect two or more logical subnets which do not necessarily map one to one to the physical. Packet mode and flow mode. Today we are going to see how switches and a router interact with each other by tracing arp and icmp packet flow.

Routers and switches are both computer networking devices that allow one or more computers to be connected to other computers networked devices or to other networks. Tracing packet flow between a 2 switches and a router.
