NEW QUESTION # 176
On the network shown in the figure, EBGP peer relationships are established between ASs through directly connected interfaces .
* OSPF is deployed in AS 65456 (with OSPF disabled on interconnected interfaces between ASs ).
* R4 and R5 use Loopback0 to establish iBGP peer relationships with R6 .
* The IP address of Loopback0 on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router .
* R1, R2, and R3 import the external route 192.168.1.0/24 into BGP through the import-route command.
Which of the following statements are true ?
Answer: A,C
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Understanding the BGP and OSPF Network Topology in the Question:
* External Route Importation
* R1, R2, and R3 import 192.168.1.0/24 into BGP from an external source.
* This means R1, R2, and R3 will advertise this route to their EBGP and iBGP peers .
* BGP Route Selection Criteria
* BGP follows specific rules to determine the best path for a route. The most relevant factors here are:
* Highest Local Preference (LOCAL_PREF) # Preferred
* Shortest AS Path # Preferred
* Lowest Origin Type (IGP < EGP < Incomplete) # Preferred
* Lowest MED (Multi-Exit Discriminator) # Preferred
* Oldest eBGP route (if paths are equal) # Preferred
Route Selection Analysis for Each Statement:
A). For 192.168.1.0/24, R5 preferentially selects the route received from R2. # (Correct)
* R5 is in AS 65456 and peers with R6 using iBGP.
* Since R2 is a central router with direct connectivity to R5 , it is the most preferred path compared to indirect paths from R1 or R3.
* By default, R5 will prefer the path from R2 over others unless explicitly influenced by BGP attributes.
# Statement A is correct.
B). For 192.168.1.0/24, R4 preferentially selects the route received from R1. # (Incorrect)
* R4 and R5 use Loopback0 to establish iBGP with R6 , meaning they receive BGP routes from multiple sources.
* BGP prefers the shortest AS path , and there is no specific information indicating that R1's path is the shortest for R4 .
* R4 may actually prefer another router ' s advertisement (e.g., R2 or R3) depending on AS path length and other attributes.
# Statement B is incorrect.
C). For 192.168.1.0/24, if the default local-preference 150 command is configured on R3, R5 preferentially selects the route received from R3. # (Correct)
* By default, BGP assigns a local-preference of 100.
* If R3 sets local-preference to 150, it is higher than other routes (R1, R2).
* BGP prefers the highest local-preference value , so R5 will prefer the route received from R3 if this attribute is set.
# Statement C is correct.
D). For 192.168.1.0/24, R6 preferentially selects the route received from R4. # (Incorrect)
* R6 is an iBGP peer of both R4 and R5.
* BGP best-path selection depends on attributes like local-preference, AS-path, and MED.
* There is no explicit information suggesting that R4's advertisement is preferred over R5's .
* R6 may prefer R5's route depending on attributes.
# Statement D is incorrect.
Final Conclusion:
# A. R5 preferentially selects the route received from R2.
# B. R4 does not necessarily prefer R1's route.
# C. If R3 sets local-preference 150, R5 will prefer the route from R3.
# D. R6 does not necessarily prefer R4's route.
Thus, the correct answers are: A, C .

NEW QUESTION # 177
After basic QinQ is configured on an interface of a switch, the switch adds the default VLAN tag of the interface to packets only when the interface receives tagged packets. In this way, the VLAN space is expanded.
Answer: B
NEW QUESTION # 178
The OSPF protocol requires routers in the same area to save the same link state database LSDB. As the number of routes on the network continues to increase, some routers cannot carry so much routing information due to limited system resources. This state is called database overload.
If all routers in an OSPE network are configured with "Isdb-overf1low-limit number 7", which of the following scenarios may cause the router to enter the Overflow state? (Multiple choice)
Answer: A,B
NEW QUESTION # 179
On the network shown in the figure, IS-IS runs on R1, R2, R4, and R5, and the area ID is 49.0001 . IS-IS runs on R3 and R6, and the area ID is 49.0002 . The import-route isis level-2 into level-1 command is configured on R2 .
In AS 65000 , R1, R3, R4, and R6 each establish iBGP peer relationships with R2 and R5 . R2 and R5 are Route Reflectors (RRs) , and R1, R4, R3, and R6 are clients .
The iBGP peer relationships are established using Loopback0 . The IP address of Loopback0 on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router .
R1 and R4 import the external route 192.168.1.0/24 to BGP through the import-route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command.
Which of the following statements are true ?
Answer: A,D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Understanding the BGP and IS-IS Network Topology in the Question:
* IS-IS Areas:
* Area 49.0001 (Level-1 IS-IS) : Contains R1, R2, R4, R5 .
* Area 49.0002 (Level-2 IS-IS) : Contains R3, R6 .
* R2 acts as an ABR (Area Border Router) and redistributes routes between Level-1 and Level-2 using import-route isis level-2 into level-1.
* BGP Route Reflection & Peering:
* R2 and R5 are Route Reflectors (RRs).
* iBGP peering is established among all routers (R1, R2, R3, R4, R5, R6).
* R1 and R4 import 192.168.1.0/24 into BGP , meaning this prefix will be advertised to all iBGP peers .
* R3 and R6 import 192.168.2.0/24 into BGP , meaning this prefix will also be advertised to all iBGP peers .
Route Distribution Analysis:
A). The route 192.168.2.0/24 in the routing table of R4 has two next hops. # (Correct)
* R3 and R6 import 192.168.2.0/24 into BGP .
* R2 and R5 (Route Reflectors) learn this route and reflect it to their clients (R1, R3, R4, R6).
* R4 receives two valid paths to 192.168.2.0/24 via R2 and R5 (both iBGP peers).
* Since both routes have the same BGP attributes and cost , they are installed as equal-cost paths in R4 ' s routing table.
# Statement A is correct: The routing table of R4 has two next hops for 192.168.2.0/24.
B). The routing table of R1 contains two equal-cost default routes. # (Incorrect)
* In an IS-IS Level-1-2 setup, default routes are usually provided to Level-1 routers from an ABR (like R2) .
* However, the question does not mention that R1 is receiving two default routes or that it is in an equal-cost multipath (ECMP) scenario.
* R1 may have only one default route, depending on route preference and cost.
# Statement B is incorrect: The routing table of R1 does not necessarily contain two equal-cost default routes.
C). The routing table of R4 contains two equal-cost default routes. # (Incorrect)
* Similar to R1, R4 is also a Level-1 router in IS-IS .
* If R4 were receiving default routes from multiple ABRs (R2 and R5), then it could have equal- cost paths .
* However, there is no indication that R4 is receiving two default routes in this scenario.
# Statement C is incorrect: The routing table of R4 does not necessarily contain two equal-cost default routes.
D). The routing table of R1 contains the route 192.168.2.0/24. # (Correct)
* R3 and R6 import 192.168.2.0/24 into BGP .
* R2 and R5 (Route Reflectors) reflect this route to their iBGP peers, including R1.
* Since R1 is an iBGP client of R2 and R5, it will receive 192.168.2.0/24 and install it in its routing table.
# Statement D is correct: The routing table of R1 contains the route 192.168.2.0/24.
Final Conclusion:
# A. The route 192.168.2.0/24 in the routing table of R4 has two next hops.
# B. The routing table of R1 does not necessarily contain two equal-cost default routes.
# C. The routing table of R4 does not necessarily contain two equal-cost default routes.
# D. The routing table of R1 contains the route 192.168.2.0/24.
Thus, the correct answers are: A, D .
