Hi I have a really stupid question. I have 2 xLayer 2 switches (Cisco) and two routers connected to those switches. One routing to another network and the other to the internet. I want to setup OSPF to enter routes dynamically. They don’t want to pick-up neighbors unless they are directly connected. Any help will [...]
In GNS, I manually assigned IP address to the serial links between two routers, and also made two more areas. All of them are running OSPF. When I restarted all the routers, I found out below that some interfaces it is shown as SLARP (using the command #show ip int brief). Does anyone know how [...]
hi , i have a cisco 1841 router connected to 2 different isp & running 2 different protocol ( ospf & bgp ) i want to use ospf link as a primary & auto switch to bgp link in case of pri link failure . i have added static route to make ospf link [...]
Now a days also why we are using RIP instead of OSPF,EIGRP.Any one knows means please tell me.
How can I configure OSPF to speed up our internal traffic using a Cisco 1800? What information do I need to begin with? Does it need to be installed on all routers? Or just one?
My question is simple. what happened if I set ip unnumbered fa0/0 in my serial interface and later my fa0/0 goes down. if I establish ospf in that network which interface will proces the hello packet and which interface via send the hello packet ?. load balance ?
Is there a way to tell OSPF to not advertise a specific network on a spefic interface without stopping the adverts of other networks? Example Router has 5 interfaces F1 is a link to another router F2 is a link to another router F3 = netB F4 = netC F5 = netD I need nets [...]

I’m moving our flat network which covers a three-story building and about 450 users to a subnetted network. I would like to know about connecting data closet switches to the core with redundant links. Can I implement OSPF on the core and connecting switches and eliminate spanning tree? In this environment do I really need [...]
