What information does the next hop entry in a routing table identify?
The first router in the path to the destination network. The next hop router is the first (or next) router in the path to the destination network. Each router looks at the destination network in the packet, then consults the routing table to identify the next hop router to the destination network. The hop count identifies the numbers of routers in the path to the destination network. A default gateway router is a router that is used for packets used to external networks. Most routers do not have a default gateway setting, but instead use a default route setting which identifies the next hop router for all unknown networks.
When devices send packets to destinations not on their segment what actions must the router take?
The router must determine if it has a path to another network or router that may be in the path of the destination. When that occurs, it tries to find the "best path" (least cost) route to the destination. It has to consult its routing tables for that.
Which information is used by the router to determine the path between the source and destination?
network portion of ip address
Which information is used by the router to determine the path between the source and destination hosts?
network portion of ip address
What device determines the destination and optimal path for messages?
router
2 How do routers use the routing table to determine the best path to a destination network?
They check the number of hops a packet passes to reach the the destination. The router then uses the route with least number of Hops.
What is an router?
router is a device which finds best possible path for the data to transfer from host to destination.................it provide shortest and clearest path for the data
What does the tracert command test?
the network path to a destination
What part of the network layer address does the router use during path determination?
routers work at layer 3 (network) which usually means TCP/IP. Routing decisions are made based on a packets DESTINATION IP address.
Which part a network layer address does the router use during path determination?
The network address
What is a router's convergence time?
the time it takes for a router to recognize a best path in the event of a change or network outage.
Which OSI layer defines the functions of a router?
Network Layer - Does path determination and logical addressing.
