What routes are present in the routing table? What two statements are correct regarding how a router forwards packets? If the packet is destined for a directly connected network, the router forwards the packet out the exit interface indicated by the routing table.

Difference between Router and Gateway – Based on internal routing tables, routers read each incoming packet and decide how to forward it. Routers work at the network layer (layer 3) of the protocol. Device that converts one protocol or format to another. A network gateway converts packets from one protocol to another.

2 Answers. It's "method A". ARP requests for addresses outside the subnet won't be sent at all. The only ARP request will be for the gateway's IP address.

Layer 3 Switches also known as multilayer switches can forward frames based on layer 2 address and packet based on layer 3 address. They infact perform the functions of both Routers and Switches.

A router is a networking device which connects two or more networks and forwards data packets between them. The TP Link or some other brand's router will enable connecting the residential or office network (LAN) with the internet (WAN).

Adjusting the router's MTU is the best solution because it avoids the need to adjust individual devices. Example: Your ISP states your internet access MTU is set to 1472. Your Router is however set to 1500 (default). Your network devices are sending packets at 1500 bytes when your network can only handle 1472 bytes.

Because of changing network conditions a router may not always pick the same route each time for your packets. When this happens, your packet may end up traversing a path that involves a different number of routers. This is why you see a different TTL. This is perfectly normal.

Routing is the decision over which interface a packet is to be sent. This decision has to be made for locally created packets, too. Routing tables contain network addresses and the associated interface or nexthop. ... Forwarding refers to packets which reach a system but are not destined for this system.

Traceroute uses the TTL (Time to Live) field in the IP packet header. Normally, TTL is used to prevent packets from being forwarded forever when there is a routing loop. Whenever an IP packet is forwarded by a router, the TTL is decreased by one. When the TTL is zero, the IP packet will be discarded.

IP forwarding is the ability for an operating system to accept incoming network packets on one interface, recognize that it is not meant for the system itself, but that it should be passed on to another network, and then forwards it accordingly.

TCP does something in between GBN and SR, closer to SR. TCP sends only one packet that it thinks is lost, not entire window, so not like GBN. TCP receiver buffers out of order segments. But ACK indicates the sequence number that is missing (unlike SR).
