Answer / Himansh Sagar

A switch operates at Layer 2 (Data Link Layer) of the OSI model, forwards data based on MAC addresses, creates a dedicated link between devices, and reduces collisions. A hub operates at Layer 1 (Physical Layer) of the OSI model, broadcasts all incoming packets to all connected devices, and does not create dedicated links. A router operates at Layer 3 (Network Layer) of the OSI model, forwards data based on IP addresses, performs routing decisions, and connects different networks.

here is your question sahin Hi Jitendera, If i m not wrong, then in EIGRP, Metric weight is set to K1(Bandwidth)=1, K2(Delay)=0, K3(Reliability)=1, K4(Load)=0, K5(MTU)=0. This is default setting for EIGRP. I knew about it from ICND 2 cisco press book. Three more questions - a) If we change the K value (I mean metric weight)on a router what will happen??? b) When redistribution is necessary in EIGRP. Is there any condition for that??? c) What is reference bandwidth for metric calculation in EIGRP. As we know, in OSPF, on a CISCO router reference bandwidth is 10Mbps.
