cisco 300-410 exam questions q5-1 cisco 300-410 exam questions q5-2

Down

This is the first OSPF neighbor state. It means that no information (hellos) has been received from this neighbor, but
hello packets can still be sent to the neighbor in this state. During the fully adjacent neighbor state, if a router doesn\\’t receive

hello packet from a neighbor within the Router Dead Interval time (RouterDeadInterval = 4*HelloInterval by default) or if the manually configured neighbor is being removed from the configuration, then the neighbor state changes from Full to Down.

Attempt

This state is only valid for manually configured neighbors in an NBMA environment. In Attempt state, the router sends
unicast hello packets every poll interval to the neighbor, from which hellos have not been received within the dead
interval.

Init

This state specifies that the router has received a hello packet from its neighbor, but the receiving router\\’s ID was not
included in the hello packet. When a router receives a hello packet from a neighbor, it should list the sender\\’s router ID in its hello packet as an acknowledgment that it received a valid hello packet.

2-Way

This state designates that bi-directional communication has been established between two routers. Bi-directional means that each router has seen the other\\’s hello packet. This state is attained when the router receiving the hello packet sees its own Router ID within the received hello packet\\’s neighbor field. At this state, a router decides whether to become adjacent with this neighbor. On broadcast media and non-broadcast multiaccess networks, a router becomes full only with the designated router (DR) and the backup designated router (BDR); it stays in the 2-way state with all other neighbors.

On Point-to-point and Point-to-multipoint networks, a router becomes full with all connected routers.
At the end of this stage, the DR and BDR for broadcast and non-broadcast multiacess networks are elected. For more
information on the DR election process, refer to DR Election. Note: Receiving a Database Descriptor (DBD) packet from
a neighbor in the init state will also a cause a transition to 2-way state.

Exstart

Once the DR and BDR are elected, the actual process of exchanging link state information can start between the
routers and their DR and BDR. (ie. Shared or NBMA networks). In this state, the routers and their DR and BDR
establish a master-slave relationship and choose the initial sequence number for adjacency formation. The router with the higher router ID becomes the master and starts the exchange, and as such, is the only router that can increment the sequence number. Note that one would logically conclude that the DR/BDR with the highest router ID will become the master during this process of master-slave relation. Remember that the DR/BDR election might be purely by virtue of a higher priority configured on the router instead of highest router ID. Thus, it is possible that a DR plays the role of slave. And also note that master/slave election is on a per-neighbor basis.

Exchange

In the exchange state, OSPF routers exchange database descriptor (DBD) packets. Database descriptors contain linkstate advertisement (LSA) headers only and describe the contents of the entire link-state database. Each DBD packet has a sequence number which can be incremented only by master which is explicitly acknowledged by slave. Routers also send link-state request packets and link-state update packets (which contain the entire LSA) in this state. The contents of the DBD received are compared to the information contained in the routers link-state database to check if new or more current link-state information is available with the neighbor.

Loading

In this state, the actual exchange of link state information occurs. Based on the information provided by the DBDs,
routers send link-state request packets. The neighbor then provides the requested link- state information in link-state
update packets. During the adjacency, if a router receives an outdated or missing LSA, it requests that LSA by sending a linkstate request packet. All link-state update packets are acknowledged.

Full

In this state, routers are fully adjacent with each other. All the router and network LSAs are exchanged and the routers\\’ databases are fully synchronized. Full is the normal state for an OSPF router. If a router is stuck in another state, it is an indication that there are problems in forming adjacencies. The only exception to this is the 2-way state, which is normal in a broadcast network. Routers achieve the FULL state with their DR and BDR in NBMA/broadcast media and FULL state with every neighbor in the remaining media such as point-to- point and point-to-multipoint.
Note: The DR and BDR that achieve FULL state with every router on the segment will display FULL/DROTHER when
you enter the show ip ospf neighbor command on either a DR or BDR. This simply means that the neighbor is not a DR
or BDR, but since the router on which the command was entered is either a DR or BDR, this shows the neighbor as
FULL/DROTHER.

Each router compares the DBD packets that were received from the other router: Exchange
+
Routers exchange information with other routers in the multiaccess network: Exstart
+
The neighboring router requests the other routers to send missing entries: Loading
+
The network has already elected a DR and a backup BDR: 2-way
+
The OSPF router ID of the receiving router was not contained in the hello message: Init
+
No hellos have been received from a neighbor router: Down

When OSPF adjacency is formed, a router goes through several state changes before it becomes fully adjacent with its
neighbor.

The states are Down -> Attempt (optional) -> Init -> 2-Way -> Exstart -> Exchange -> Loading -> Full. Short descriptions about these states are listed below:

Down: no information (hellos) has been received from this neighbor. Attempt: only valid for manually configured
neighbors in an NBMA environment. In Attempt state, the router sends unicast hello packets every poll interval to the
neighbor, from which hellos have not been received within the dead interval.

Init: specifies that the router has received a hello packet from its neighbor, but the receiving router\\’s ID was not
included in the hello packet

2-Way: indicates bi-directional communication has been established between two routers. Exstart: Once the DR and
BDR are elected, the actual process of exchanging link state information can start between the routers and their DR
and BDR.

Exchange: OSPF routers exchange and compare database descriptor (DBD) packets Loading: In this state, the actual
exchange of link state information occurs. Outdated or missing entries are also requested to be resent.

Full: routers are fully adjacent with each other

Correct Answer:

cisco 300-410 exam questions q9-1

Unlike legacy network technologies such as ISDN, Frame Relay, and ATM that defined separate data and control
channels, IP carries all packets within a single pipe. Thus, IP network devices such as routers and switches must be
able to distinguish between data plane, control plane, and management plane packets to treat each packet
appropriately. From an IP traffic plane perspective, packets may be divided into four distinct, logical groups:

1.

Data plane packets -End-station, user-generated packets that are always forwarded by network devices to other endstation devices. From the perspective of the network device, data plane packets always have a transit destination IP
address and can be handled by normal, destination IP address- based forwarding processes.

2.

Control plane packets -Network device generated or received packets that are used for the creation and operation of
the network itself. From the perspective of the network device, control plane packets always have a receive destination
IP address and are handled by the CPU in the network device route processor. Examples include protocols such as
ARP, BGP, OSPF, and other protocols that glue the network together.

3.

Management plane packets -Network device generated or received packets, or management station generated or
received packets that are used to manage the network. From the perspective of the network device, management plane
packets always have a receive destination IP address and are handled by the CPU in the network device route
processor. Examples include protocols such as Telnet, Secure Shell (SSH), TFTP, SNMP, FTP, NTP, and other
protocols used to manage the device and/or network.

4.

Services plane packets -A special case of data plane packets, services plane packets are also user- generated packets
that are also forwarded by network devices to other end-station devices, but that require high-touch handling by the
network device (above and beyond normal, destination IP address-based forwarding) to forward the packet.
Examples of high-touch handling include such functions as GRE encapsulation, QoS, MPLS VPNs, and SSL/IPsec
encryption/decryption, etc. From the perspective of the network device, services plane packets may have a transit
destination IP address, or may have a receive destination IP address (for example, in the case of a VPN tunnel
endpoint).

cisco 300-410 exam questions q11

A. Pop the label
B. Impose the label
C. Include the EXP bit
D. Exclude the EXP bit

The imp-null (implicit null) tag instructs the upstream router to pop the tag entry off the tag stack before forwarding the packet. Note: pop means remove the top MPLS label
