NEW QUESTION # 73
IS-IS LSP fragments are identified by the LSP Number field in their LSP IDs. This field is 4 bits long.
Therefore, an IS-IS process can generate a maximum of 256 LSP fragments, which means only a limited amount of information can be carried. By adding additional system IDs, you can enable the IS-IS process to generate more LSP fragments.
Options:
Answer: A
Explanation:
Comprehensive and Detailed In-Depth Explanation:
* In IS-IS (Intermediate System to Intermediate System), each LSP (Link-State PDU) is identified by an LSP ID.
* The LSP Number field is 4 bits long, meaning a single IS-IS process can generate up to 16 LSP fragments per system ID.
* Since each fragment carries a limited amount of information, a router may exceed this limit if it needs to advertise a large number of routes.
* Solution: By adding additional system IDs, an IS-IS router can generate more LSP fragments, thereby overcoming the limitation.
* This method is commonly used in large-scale IS-IS networks to ensure scalability and efficient routing information exchange.

NEW QUESTION # 74
On the OSPF network shown in the figure, area 1 is an NSSA , area 2 is a stub area , and R4 imports an external route 10.0.4.4/32 . The router ID of each router is 10.0.X.X , where X is the router number . The asbr-summary 10.0.4.0 255.255.255.0 command is configured in the OSPF processes of R1 and R3 .
Match the following descriptions of routing tables with the corresponding routers :
Answer:
Explanation:
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Key OSPF Concepts to Consider:
* Area 1 is an NSSA (Not-So-Stubby Area):
* NSSAs allow external routes but advertise them as Type-7 LSAs.
* The ABR (R2) converts these Type-7 LSAs into Type-5 LSAs for the backbone (Area 0).
* Area 2 is a Stub Area:
* Stub areas do not allow external routes (Type-5 LSAs) .
* This means that R5 (inside Area 2) will NOT receive external routes like 10.0.4.4/32 or
10.0.4.0/24 .
* Effect of asbr-summary 10.0.4.0 255.255.255.0 on R1 and R3:
* This command ensures that R1 and R3 will see a summarized route 10.0.4.0/24 instead of specific /32 routes .
Routing Table Analysis:
* R1 (ABR for NSSA, with ASBR summary configured)
* Connected to Area 1 (NSSA) and Area 0 (Backbone)
* Since asbr-summary 10.0.4.0 255.255.255.0 is configured on R1, it contains both 10.0.4.4/32 (from R4) and the summarized 10.0.4.0/24 .
* # Matches Option 4: The routing table contains both 10.0.4.4/32 and 10.0.4.0/24.
* R5 (Inside Area 2 - Stub Area)
* Stub areas do not receive external routes (Type-5 LSAs) .
* Since R5 is inside a stub area, it does not contain 10.0.4.4/32 or 10.0.4.0/24 .
* # Matches Option 3: The routing table does not contain 10.0.4.4/32 or 10.0.4.0/24.
* R2 (ABR between NSSA and Backbone, but no ASBR summary configured)
* R2 converts Type-7 LSAs from R4 into Type-5 LSAs and advertises them into Area 0.
* Since no ASBR summary is configured on R2 , it only sees the specific external route 10.0.4.4
/32 but not the summarized 10.0.4.0/24 .
* # Matches Option 1: The routing table contains 10.0.4.4/32 only.
* R3 (Another ABR with ASBR summary configured)
* R3 has asbr-summary 10.0.4.0 255.255.255.0 configured, which means it will summarize the external routes.
* Instead of 10.0.4.4/32, R3 will only have the summarized 10.0.4.0/24 route.
* # Matches Option 2: The routing table contains 10.0.4.0/24 only.
