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.
