How are directly connected and local routes created?
Directly connected and local routes are automatically created whenever an interface is configured with an IP address and activated. Match the routing table entry to the corresponding function. (Not all options are used.) - identifies how the route was learned: route source - identifies the address of a remote network: destination network
What is the route source code for a directly connected interface?
Directly connected interfaces have two route source codes. C identifies a directly connected network. Directly connected networks are automatically created whenever an interface is configured with an IP address and activated. L identifies that this is a local route.
Which command would be used to configure a router to automatically summarize?
To configure a router to automatically summarize networks, the auto-summary command would be used. Which two route source codes are automatically created within a routing table whenever a router interface is configured with an IP address and activated? (Choose two.) - C - D Refer to curriculum topic: 3.3.1:
How are routing table entries created on a router interface?
Notice that two routing table entries are automatically created when an active router interface is configured with an IP address and subnet mask. Figure 3-53 displays one of the routing table entries on R1 for the directly connected network 172.16.1.0.
When would it be more beneficial to use a dynamic routing protocol instead of static routing?
on a network where there is a lot of topology changes
When would it be more beneficial to use static routing instead of dynamic routing protocols?
on a network where dynamic updates would pose a security risk
What is a purpose of the network command when configuring RIPv2 as the routing protocol?
It identifies the interfaces that belong to a specified network.
What is the purpose of the passive-interface command?
allows a router to receive routing updates on an interface but not send updates via that interface
What is dynamically built routing table?
A dynamically built routing table provides a great deal of information, as shown in Figure 3-55. Therefore, it is crucial to understand the output generated by the routing table. Special terms are applied when discussing the contents of a routing table.
What is a level 1 parent route?
The routing table hierarchy in Cisco IOS has a classful routing scheme. A level 1 parent route is the classful network address of the subnet route. This is the case even if a classless routing protocol is the source of the subnet route.
What is the routing table of R1?
The routing table of R1 is displayed in Figure 3-69 using the show ipv6 route command. Although the command output is displayed slightly differently than in the IPv4 version, it still contains the relevant route information.
How many bits are needed to match IPv4 address?
For there to be a match between the destination IPv4 address of a packet and a route in the routing table, a minimum number of far left bits must match between the IPv4 address of the packet and the route in the routing table.
What is Cisco routing table?
The routing table hierarchy in Cisco IOS was originally implemented with the classful routing scheme. Although the routing table incorporates both classful and classless addressing, the overall structure is still built around this classful scheme.
Why is it important to know the routing table?
As a network administrator, it is important to know the routing table in depth when troubleshooting network issues. Understanding the structure and lookup process of the routing table will help you diagnose any routing table issue, regardless of your level of familiarity with a particular routing protocol.
Why are serial links used?
The reference bandwidth is not a realistic representation of modern networks. It is used only to provide a visual sense of link speed.
What is routing protocol?
Fill in the blank. routing protocols are used to dynamically exchange routing information between routers. Noted: In netacad system, you can use one of the following: “ routing ” or “ dynamic routing “. But in our system, you can use only “ routing “.
What is dynamic routing?
Explanation: Dynamic routing protocols exist to discover the network, maintain routing tables, and calculate the best path. Having low levels of routing overhead, using the path specified by the administrator, and avoiding the exposure of network information are functions of static routing. Refer to the exhibit.

What is IPv6 routing?
In IPv6, all routes in the routing table are level 1 ultimate routes and contain a next-hop IPv6 address or exit interface or both.When a match is found, the traffic is forwarded.
Is dynamic routing better than static routing?
Dynamic routing is simpler to configure than static routing in larger networks. Static routing does not scale well as networks grow in size. Refer to the exhibit. All hosts and router interfaces are configured correctly.
What is a default route?
A default route is a level 1 ultimate route, but not all ultimate routes are default routes. Routing table entries that are subnetted are level 1 parent routes but do not meet either of the two requirements to be ultimate routes. Ultimate routes do not have to be classful network entries.
Which protocol consumes more router resources?
on a network where there is a lot of topology changes. Explanation: Dynamic routing protocols consume more router resources, are suitable for larger networks, and are more useful on networks that are growing and changing.
What is dynamic routing?
Dynamic routing is when a routing protocol is used. Static routing is when every remote route is entered manually by an administrator into every router in the network topology. From year to year, Cisco has updated many versions with difference questions. The latest version is version 6.0 in 2018.
What is RIP protocol?
Explanation: The RIP protocol was created with a metric that does not support larger networks. Other routing protocols, including OSPF, EIGRP, and IS-IS, scale well and accommodate growth and larger networks.
What is ultimate route?
Explanation: An ultimate route is a routing table entry that contains either a next-hop IP address (another path) or an exit interface, or both. This means that directly connected and link-local routes are ultimate routes. A default route is a level 1 ultimate route, but not all ultimate routes are default routes.
Is IPv6 classless?
By design IPv6 is classless so all routes are effectively level 1 ultimate routes. The selection of IPv6 routes is based on the shortest matching prefix, unlike IPv4 route selection which is based on the longest matching prefix. IPv6 does not use static routes to populate the routing table as used in IPv4.
What is a default route?
A default route is a level 1 ultimate route, but not all ultimate routes are default routes. Routing table entries that are subnetted are level 1 parent routes but do not meet either of the two requirements to be ultimate routes. Ultimate routes do not have to be classful network entries. 14.
When to use static and dynamic routing?
Both static and dynamic routing could be used when more than one router is involved. Dynamic routing is when a routing protocol is used. Static routing is when every remote route is entered manually by an administrator into every router in the network topology.
What is RIP protocol?
The RIP protocol was created with a metric that does not support larger networks. Other routing protocols, including OSPF, EIGRP, and IS-IS, scale well and accommodate growth and larger networks. 3.
