  The network engineer configured the summarization of the RIP routes into the OSPF domain on R5 but still sees four different 172.16.0.0/24 networks on R4. Which action resolves the issue?

  A. R5(config)#router ospf 1 R5(config-router)#no area R5(config-router)#summary-address 172.16.0.0 255.255.252.0
  B. R4(config)#router ospf 99 R4(config-router)#network 172.16.0.0 0.255.255.255 area 56 R4(config-router)#area 56 range 172.16.0.0 255,255.255.0
  C. R4(config)#router ospf 1 R4(config-router)#no area R4(config-router)#summary-address 172.16.0.0 255.255.252.0
  D. R5(config)#router ospf 99 R5(config-router)#network 172.16.0.0 0.255.255.255 area 56 R5(config-router)#area 56 range 172.16.0.0 255.255.255.0

  Area 36 is a NSSA so R5 is an ASBR so we can summarize external routes using the "summaryaddress" command. The command "area area-id range" can only be used on ABR so it is not correct. The summarization must be done on the ASBR which is R5, not R4 so the correct answer must be started with "R5(config)#router ospf 1". Note: The "no area" command is used to remove any existing "area ..." command (maybe "area 56 range ..." command).

• Question 436:

  Which command shows only OSPF routes installed into the routing table?

  A. show ip route
  B. show ip ospf route
  C. show ip route ospf
  D. show ip ospf
  E. show ip ospf database
  C. show ip route ospf

  ---

  The correct answer is show ip route ospf.

  The show ip route ospf command shows you all the OSPF learned routes in the routing table. An example of the command and its output are below with an explanation of some of the terminology.

  Router5# show ip route ospf

  O IA 10.0.0.0/8 [110/65] via 5.0.0.2, 00:00:20, Serial1/1/0 S 0.0.0.0/0 [110/1] via 5.0.0.2, 00:00:20, Serial1/1/0 O E2 172.16.0.0 [110/25] via 5.0.0.2, 00:00:30, Serial1/1/0

  -indicates that the route was learned from OSPF.

  IA - indicates that the route is an inter area route, meaning it was learned via summary type 3 link state advertisements (LSAs). S - indicates that a static default route has been configured. E2 - indicates that the route is an external router redistributed from another protocol. Via - indicates the next hop address to use and the local interface from which to send [110/65]- indicates the administrative distance with the first value and the cost in the second (AD/cost).

  The full legend of the possible route codes is below:

  Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2

  i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

  * - candidate default, U - per-user static route, o - ODR

  P - periodic downloaded static route

  The commands below can be used to monitor and verify OSPF operation:

  show ip route - displays known routes and from which protocol the routes were discovered, but for all routing protocols, not just OSPF. show ip ospf - displays the number of times the SPF algorithm has run and the default Link State Update (LSU) interval, but not the OSPF routes. show ip ospf database - displays the router ID, the OSPF process ID, and the contents of the topological database but not the routing table.

  There is no show ip ospf route command.

  Sub-Objective:

  Configure and verify OSPF operations

  D. enable-password Cisco@123

• Question 438:

  Which statements in regards to route filtering are true? (Choose two.)

  A. Network security is the primary role of route filtering.
  B. If no route filter exists for an interface, the packet is processed normally.
  C. Route filtering on an interface cannot filter routes that originate from the same router.
  D. The distribute-list command enables the administrator to filter redistributed routes.
  E. The network keyword of the passive-interface command enables you identify the routes to advertise.
  B. If no route filter exists for an interface, the packet is processed normally.
  D. The distribute-list command enables the administrator to filter redistributed routes.

  ---

  Distribute lists are used to filter inbound, outbound, or redistributed routing updates. Instead of using the passive-interface command, distribute lists enable you to selectively control which routes are processed.

  If no distribute list is associated with the interface, the routing update packets are processed normally.

  If a distribute list is associated with an interface, the routing update is compared to the access list that was specified in the distribute list. If a match is found to a permit statement, then the packet is forwarded. If a match is found to a deny statement, the packet is discarded. If no match is found, the implicit deny statement at the end of the access list will drop the packet.

  Network security is not the primary role of route filtering. Its primary function is to reduce unnecessary routing update traffic.

  Route filtering on an interface can filter routes that originate from the same router.

  The network keyword of the passive-interface command does not enable you identify the routes to advertise.

  Objective:

  Layer 3 Technologies

  Sub-Objective:

  Configure and verify filtering with any protocol

  A DHCP server that receives a DHCPDISCOVER message may respond with a DHCPOFFER message on UDP port 68 (BootP client).

  ...

  In the event that the DHCP server is not on the local subnet, the DHCP server will send the DHCPOFFER, as a unicast packet, on UDP port 67, back to the DHCP/BootPRelay Agent from which the DHCPDISCOVER came.
