1. What is the default Hello interval for OSPF in a LAN?
These routes are Type-1 external routes. They define networks outside of the autonomous system and are advertised by Type 5 LSAs. The cost is calculated by adding the external cost to the internal cost of each link that the packet crosses. The use of
10 seconds is the default Hello interval and the default Dead interval is 4 times that value.
The BGP process injects local routes in two different ways[md]1) using the network configuration commands and 2) using redistribution by another routing protocol.
Router(config-router)# neighbor {ip-address | peer-group-name} prefix-list prefix-listname {in | out}

2. What key design requirement of BGP does a BGP route reflector address?
You can use the show ip ospf command to verify the router ID of an OSPF-speaking router.
Route reflectors help address the fact that BGP requires that all BGP peers in the same autonomous system form an Internal BGP (IBGP) session with all peers in the autonomous system.
For the nonbroadcast (NBMA) RFC-compliant mode of operation: Dynamic or manual neighbor configuration? Manual - DR/BDR election required? DR/BDR election
200

3. Open
After a neighbor is configured - BGP sends an open message to try to establish peering with that neighbor. Includes information such as autonomous system number - router ID - and hold time.
The default LSA aging timer is 30 minutes.
Use the bgp default local-preference command to change the default local preference value applied to all updates coming from external neighbors or originating locally.
For the nonbroadcast (NBMA) RFC-compliant mode of operation: Dynamic or manual neighbor configuration? Manual - DR/BDR election required? DR/BDR election

4. You can manipulate the administrative distance of three different types of OSPF routes. What are the three types?
Access list or L2 problem blocking Hellos in one direction - Multicast non-functional on one side - Authentication configured on only one side - broadcast keyword missing from the map command
Three different administrative distance values are possible for OSPF[md]intra-area routes - inter-area routes - and external routes. By default all are set to 110.
The command is applied on all routers in the area.
Use the variance command in EIGRP to control load balancing behavior[md]potentially across unequal bandwidth links.

5. What does a Type 7 LSA describe - what router produces it - and Where is it flooded by default?
Exterior Gateway Protocol(EGP). BGP v4 is the only EGP currently in use.
To qualify as a feasible successor - a next hop router must have an AD less than the FD of the current successor route. More than one feasible successor can exist.
The NSSA External (Type 7) LSA is almost identical to a Type 5 AS External LSA - yet it is used to create Not-So-Stubby Areas. An NSSA ASBR generates this LSA - and an NSSA ABR translates it into a Type 5 LSA - which gets propagated into the OSPF dom
The AS External (Type 5) LSAs advertise an external destination or a default route to an external destination. These LSAs are originated by ASBRs. They are flooded throughout the autonomous system.

6. What command do you use in OSPF to configure inter-area route summarization on the ABR?
BGP speakers
Use the following command to configure inter-area route summarization on the ABR: Router(config-router)# area area-id range address mask
The O indicates the route is an OSPF intra-area route. The network destination is within the same area as the router on which this command is issued.
The NSSA External (Type 7) LSA is almost identical to a Type 5 AS External LSA - yet it is used to create Not-So-Stubby Areas. An NSSA ASBR generates this LSA - and an NSSA ABR translates it into a Type 5 LSA - which gets propagated into the OSPF dom

7. What does a Type 4 LSA describe - what router produces it - and Where is it flooded by default?
An autonomous system is a group of networks under a common administration. The Internet Assigned Numbers Authority(IANA) assigns AS numbers: 1 to 64511 are public AS numbers and 64512 to 65535 are private AS numbers.
The NSSA External (Type 7) LSA is almost identical to a Type 5 AS External LSA - yet it is used to create Not-So-Stubby Areas. An NSSA ASBR generates this LSA - and an NSSA ABR translates it into a Type 5 LSA - which gets propagated into the OSPF dom
The ASBR Summary (Type 4) LSA advertises an Autonomous System Boundary Router (ASBR) destination. This LSA is originated at an ABR. This LSA type is flooded throughout an autonomous system.
The O indicates the route is an OSPF intra-area route. The network destination is within the same area as the router on which this command is issued.

8. You are interested in monitoring the use of your regular expressions for manipulating the BGP routing process. What command can you use to display routes matching the AS-path regular expression?
An OSPF stub area is an area into which External LSAs are not flooded (Type 4 and 5 LSAs are blocked.) Type 1 - 2 - and 3 LSAs are still used in a stub area.
To display routes matching the AS-path regular expression - use the show ip bgp regexp command.
The default cost of the default route is 1.
10 seconds is the default Hello interval and the default Dead interval is 4 times that value.

9. What does a Type 2 LSA describe - what router produces it - and Where is it flooded?
The Network LSA (Type 2) lists all attached routers. These LSAs are produced by the DR on every multi-access network. They are flooded within the originating area.
You can use the show ip ospf command to verify the router ID of an OSPF-speaking router.
EIGRP uses up to 50 percent of the bandwidth (as set by the bandwidth command) for its operations.
The highest IP address of an active interface is selected; any loopback interface overrides this behavior. Therefore - if you have loopback interfaces - the highest IP address on an active loopback interface is selected.

10. You are examining the results of the show ip route command - and you notice several OSPF routes bear an O IA route designator. What does this signify?
Router(config)# ip community-list 1-99 permit|deny value [ value ... ]
These route types are OSPF inter-area routes. They define networks outside of the area of the router - but within the autonomous system. Type 3 LSAs are used to advertise these route types.
The minimum metric of the specific routes is used as the metric of the summary route.
BGP speakers

11. What is the feasible successor in EIGRP?
Router(config-router)# neighbor {ip-address | peer-group-name} prefix-list prefix-listname {in | out}
Router(config-router)# neighbor ip-address shutdown
The next hop router for a backup path is called the feasible successor.
A site connected to more than one ISP at the same time. It is done for redundancy and backup if one ISP fails - and for better performance if one ISP provides a better path to frequently used networks. This also gives you an ISP-independent solution.

12. What kind of routing protocol is BGP?
EIGRP uses the multicast IP address of 224.0.0.10 for Hellos and routing updates.
BGP is a path-vector protocol
You can configure manual manipulation of the AS-path attribute with the set as-path prepend command.
Cisco's implementation of OSPF calculates the metric using the following formula: - cost = refbw/bandwidth - The default refbw is 100 Mbps.

13. Describe External BGP.
External BGP is a BGP peering relationship between routers in different autonomous systems.
Cisco's implementation of OSPF calculates the metric using the following formula: - cost = refbw/bandwidth - The default refbw is 100 Mbps.
The default value of the MED attribute is 0.
Router# clear ip bgp ip-address soft out

14. What is the command that you use in EIGRP to control the load balancing across unequal cost paths?
To ensure that the router ID can be pinged - be sure to advertise the address using the appropriate network command.
An autonomous system is a group of networks under a common administration. The Internet Assigned Numbers Authority(IANA) assigns AS numbers: 1 to 64511 are public AS numbers and 64512 to 65535 are private AS numbers.
Use the variance command in EIGRP to control load balancing behavior[md]potentially across unequal bandwidth links.
Local preference can be used to enact global autonomous system routing policies.

20. When an EIGRP-speaking router receives Hello packets from a neighbor for the first time - How does the router respond if it has matching Hello parameters in the packet?
Using the default-network command - you can configure a default route for the EIGRP process so that it propagates to other EIGRP routers within the same autonomous system.
The router responds with an update of the routing information it possesses.
After a neighbor is configured - BGP sends an open message to try to establish peering with that neighbor. Includes information such as autonomous system number - router ID - and hold time.
Router(config-router)# area area_id authentication message-digest Note: Additional (interface configuration) commands are required for the configuration of authentication - but this is the router configuration command required.

23. You are considering manipulating the K values on an EIGRP router. Which routers in the EIGRP domain must have this configuration made?
These are Type-2 external routes. Again - they define networks outside of the autonomous system and are advertised by Type 5 LSAs. In this case cost is always the external cost only. This is the default OSPF external route type on Cisco routers.
The O indicates the route is an OSPF intra-area route. The network destination is within the same area as the router on which this command is issued.
When a problem occurs that causes a router to end the BGP peering session - a notificationmessage is sent to the BGP neighbor and the connection is closed.
You must manipulate the K values on all routers if you plan to manipulate them on one.
