Question: Hello,I have some questions reagrding OSPF metric calculation. Within network configuration I have uploaded, I have shown two routing tables, with lines indicating which router they are from. I understand that the OSPF metric calcualtion uses...

Each multi-access segment (ex: Ethernet Segment), will have 1 DR and 1 BDR. Each router on the segment forms a Full adjacency with the DR/BDR. Keep in mind that a router might be a DR/BDR on one of its attached multi-access networks, and it might not...

OSPF is an interior gateway routing protocol that uses link states rather than distance vectors for path selection. OSPF propagates link-state advertisements rather than routing table updates. Because only LSAs are exchanged instead of the entire routing...

Question: Since using version 5 I have one recurring issue with a couple of Cisco WS-C3750X-48T-L Stacks. When it runs the scan it returns the model and IOS version but no interfaces. After the scan snmp no longer works on the stack reporting 'queue length...

Before you configure EIGRP, there are some things you should know about it first. Here they are: EIGRP is the Enhanced Interior Gateway Routing Protocol. EIGRP is a Cisco proprietary routing protocol based on their original Interior Gateway Routing Protocol....

Cisco Express Forwarding (CEF) is an advanced layer 3 switching technology used mainly in large core networks or the Internet to enhance the overall network performance. Although CEF is a Cisco proprietary protocol other vendors of multi-layer switches...

Type-1 LSA – It’s is the Router LSA; this is defined in order to send the link state information about the attributes of the directly connected routes, besides of that you have just ONE type-1 LSA per every router inside your area. Type-2 LSA – It’s the...
