Virtualization, networking, security, and storage. I've seen many small shops where part of the IT tasks was done by an accountant or the manager itself as those small shops simply cannot afford to have an IT person working full-time.
So this is sometimes a real challenge. The lab PDF guide itself is good for walking you through the labs. If you're not into video courses, you can always seek online to learn the different network terminology and technologies. The internet is a waste resource.

But we can tune the timers to converge it little faster. Is that clear to you? Next, we will verify split-horizon, it is basically used to prevent loop in the RIP. Split-horizon says, if an update is received on an interface the same update will not be sent back over the same interface.
Basically split-horizon need to disable on Hub router in Hub and Spoke topology, where Hub router need to send back same update over the same interface to share the routing update with Spoke routers. Once best path was found then it will be installed in Routing table. Wildcard mask is opposite of subnet mask. If you know the subnet mask easily you can calculate wild card mask. For example, you have a subnet Just follow me. Now we will check Neighbor Table on R2. Now let me explain each and every field of this output.
It starts from 0 and first neighbor will use 0. The amount of time in milliseconds that EIGRP will wait before retransmitting a packet from the retransmission queue to this neighbor. Ideally you want this number to be 0 otherwise it might be an indication of congestion on the network. Just notice here, R2 is learning route When the route is leaning from R1 it has metric and when it is learning from R3 it has metric Metric lowest is best.
Next we will verify routing table and we will see route Same you may verify for route As discussed above, R2 will install route So it means, in topology table we can see router is learning one route from many different neighbors but routes from best neighbor will be installed in routing table. Now we will do the ping test from PC. Let me explain first what is load balancing, Cisco router cannot do the actual load balancing, but still we say router is doing load balancing.
Cisco router can do load sharing, it is basically, when router will send data to destination it will use multiple path to send data towards destination. So multiple path must be exist in the routing table to accomplish this. As we know in topology table EIGRP can keep multiple path for same destination and best path will be chosen based on metric and put it in routing table.
What about those paths which was not chosen as best path? These paths also can be installed in the routing table by configuring variance under EIGRP global process.
Condition is — route must be meeting feasibility condition. Actually the metric from a router to destination. This is actually metric from my neighbor router to destination.
It other words, it is the metric of the route used by the neighboring router to reach the network. Actually it is backup route, store in topology table. What is feasible condition? EIGRP uses feasible condition to select backup route or feasible successor and keep these routes in topology table. In our case, route Equal cost load balancing can happen automatically, but unequal cost load balancing cannot happen automatically.
We have configure for that, the configuration will be done under EIGRP routing process using command variance [multiplier]. The biggest drawback of variance command is, it will take effect of all routes those are fall under this condition. You cannot do it for a single route. Now we will check routing table of R2 to check whether the route But what about the route Now we will verify the timers on R2.
Cisco recommends, when you are changing hello and hold time please do change on all the interfaces throughout the EIGRP routing domain. Because, the interface is not able send hello to maintain neighborship. Dual-homed WAN connections have more management-application overhead than single-homed connections. Dual-homed WAN connections require more skill to administer than single-homed connections. Dual-homed WAN connections have a simpler topology than single-homed connections.
Broadcast B. Select and Place:. Correct Answer: D. Hosts in the server farm are unable to communicate with each other. The primary VLAN and hosts are able to reach community ports. After you apply the given configuration to arouter, the DHCP clients behind the device connot communicate with hosts outside of their subnet. Which action is most likely to correct the problem? Configure the dns server on the same subnet as the clients B.
