So that is how the network statement works!

[@Santucci73]

Dude, that was probably the best explanation that I've ever heard about the network statement and I'm a ccnp. Great Video for all those that aren't clear on the topic.

[@SalahJawad]

Thanks and informative as usual. I just can't pass by after watching any of your videos withing expressing my gratitude.

Ketih you are the greatest teacher there is.

[@KeithBarker]

Thanks Brian! I appreciate your feedback. Best wishes, Keith

Hi Ben. If you configure the OSPF in the interface, you don't need the network statement. There is no equivalent interface option in IPv4 for RIP or EIGRP (but that is how it is done in IPv6).

Thank you very much, your analogy is very good.

:) thanks man, you just saved me a lot of time...going for my CCNA next month...

Hello Shahed- Great question. ACLs and Network Statements (OSPF and EIGRP) are the only places we use the wildcard mask. Keith

[@KeithBarker]

Hello Jaelyn- Thanks for the question. On a Cisco router running IPv4 and EIGRP we use network statements in router configuration mode. On a Cisco router running IPv4 and OSPF, we could use the network statements in router configuration mode OR interface configuration statements to enable OSPF on those individual interfaces. In IPv6, the network statements are gone, and we only use interface commands for RIP, OSPF and EIGRP. Does that help with your question?

i appreciate pro , you have explain it in a very simple way

[@KeithBarker]

Thank you Alaa Alktawy!

great video!

Thank you, thank you, thank you so much for your immediate reply.

[@mohamedguezouri4175]

great corse Keith, thank you

[@shahedmohammed7451]

Great Video...Thank you so much for this Video.. Basically, where else we can use Wild card mask apart from ACL defining Network in OSPF and EIGRP apart from this do we have any other area where we can define in Wildcard Mask?

[@Yugandhar635]

@Keith6783 But the EIGRP should advertise its entire routing table to its neighbor. Here R1 and R2 are neighbors. In R1's routing table we have loop back interfaces as directly connected. As you said network command is a qualifier to include an interface in the routing protocol, Here R1's interface included in EIGRP process and from that interface eigrp should advertise its entire routing table (entire best paths) to its Neighbor.

Thanks wally

[@Yugandhar635]

Hi Keith, In R1 say there is fa0/0 with ip 192.168.4.1/24,enabled eigrp on this interface This fa0/0 is connected to another router R2 fa0/1 and its ip add 192.168.4.2 /24 and also enabled eigrp on this interface.Now I haven't enabled eigrp on the loop back interfaces of R1 though assigned ip addresses for loop back interfaces.Both R1&R2 are directly connected have become eigrp neighbors as we enabled eigrp on their fa0/0 and fa0/1. Now will the R1 advertise its loop back networks to R2 ?

Keith, Pertaining to the video, what's the difference between the following two commands. network 0.0.0.0 0.0.0.0 v/s network 0.0.0.0 255.255.255.255

[@jaelyncane5879]

isnt it done by the command prompt or something else just asking

[@roguebeez]

I read it is possible to enable OSPF on the interface using the command (config-if)# ip ospf 1 area 0 Using this method do you still need to use the network statement for the "roll-call" ? Also could this method be used for RIP and EIGRP?
