    simple routing question

    -Post your arp of PC2 and router1 -do the below steps to get some more idea 1.clear arp entry on router1 and PC 2 2.ping from PC2 3.check arp in PC 4.post the arp results here General terms: when you ping an ip in same network, PC never worry about gateway. It simply sent arp request ( broadcast ) to get the mac of destination IP When you ping an IP in different network, PC will send arp request ( broadcast ) to get the mac of gateway IP to build Layer 2 packet So as we all know gateway always must be the same network You can test the "Generea terms" by using GNS and wireshark . Install wireshark on PC and esatblish "cloud" connection to router on GNS. Run debug arp on the router. do ping from pc to different network and same network . also ping from pc with & with out gateway . whenever ping from pc check the debug output in router

    aceess-list for router input traffic

    Thanks Lord .. However "Network-Based Application Recognition (NBAR) includes a feature called Protocol Discovery. Protocol Discovery provides an easy way to discover the application protocols that are operating on an interface" It show protocal base output. not ip based.. I need to see ip based output .. Could you kindly put little more efforts on this ? i have statseeker .. i can see the whole utilization .. not ip based.. is there any way by this ? thanks in advance
  5. Hi all, Could some one gimme how to find out input traffic on perticular interface ? ip accounting will help for outbound traffic. what about inbound traffic ? Can we apply ACL with debug to find out inbound traffic ? My case is i have WAN like and it's Rx is high utilized . So i want to find out who are all in top utilization thanks in advance

    Ospf Lsa 2

    hi thanks for the reply ... mmmm How you are telling that DR save the bandwidth ( i have read the same in book also ).. i couldn't get ... See let's take an example .. Assume in a broadcast network there are 10 routers R1 to R10 ... R1 is a DR R2 is BDR ... assume some changes happened in R5 router .. Obviously it'll update to DR and BDR .. so one way traffic from R5 to R1, R2 .. Next R1(DR) will update to all ospf network except R5 .here R3,R4 and R6 to R10 .. so again traffic will go all routes from R1 except R2,R5 .. ok Now forget about DR and BDR concept in broadcast network ... What will happen when some changes happened in R5 it'll update to all routes except R5 .. only one way traffic ...? can you you tell me where the bandwidth gonna save here ...? see it's up to my knowledge ... but when we user DR and BDR there may be easy administration .. but bandwidth save ...? friend let's love all the protocols like our child .. ?

    Ospf @ Layer 4

    Dear dreamer2062 ... "Protocol" filed helps to identify which kind of information IP packet contains in its "data" filed .... my ques is will this L3 information (OSPF PACKET) move layer 4 function or not ..? then What about BGP packet will bgp packet move to layer 5 function ( because BGP packet identify by TCP port 179,so layer 4) and further ?

    Ospf @ Layer 4

    I have a clarification ... OSPF works at layer 3 with protocol number 89 .. ok what is the message format in transport layer ..? i think encapsulation happends up to layer 3 it self than packet will be forwared is it right ? this same concept will match for other protocol ... i mean BGP information will be encapsulated up tp application level .. coz it uses TCP port number 179... or will encapsulation stop layer 4 itself then packet will forward is it right pls clear my concepts .. thanks in advance
