NEW QUESTION 169
Refer to the exhibit.
An engineer is trying to generate a summary route in OSPF for network 10.0.0.0/8, but the summary route does not show up in the routing table. Why is the summary route missing?
- A. The summary route is visible only in the OSPF database, not in the routing table.
- B. The summary route is not visible on this router, but it is visible on other OSPF routers in the same area.
- C. The summary-address command is used only for summarizing prefixes between areas.
- D. There is no route for a subnet inside 10.0.0.0/8, so the summary route is not generated.
Answer: D
Explanation:
The -summary-address is only used to create aggregate addresses for OSPF at an autonomous system boundary. It means this command should only be used on the ASBR when you are trying to summarize externally redistributed routes from another protocol domain or you have a NSSA area. But a requirement to create a summarized route is:
-The ASBR compares the summary route's range of addresses with all routes redistributed into OSPF on that ASBR to find any subordinate subnets (subnets that sit inside the summary route range). If at least one subordinate subnet exists, the ASBR advertises the summary route.

Answer: C
Explanation:
Restrictions for IPv6 RA Guard
* The IPv6 RA Guard feature does not offer protection in environments where IPv6 traffic is tunneled.
* This feature is supported only in hardware when the ternary content addressable memory (TCAM) is programmed.
* This feature can be configured on a switch port interface in the ingress direction.
* This feature supports host mode and router mode.
* This feature is supported only in the ingress direction; it is not supported in the egress direction.
* This feature is not supported on EtherChannel and EtherChannel port members.
* This feature is not supported on trunk ports with merge mode.
* This feature is supported on auxiliary VLANs and private VLANs (PVLANs). In the case of PVLANs, primary VLAN features are inherited and merged with port features.
* Packets dropped by the IPv6 RA Guard feature can be spanned.Reference:

aggregate-address 172.16.20.0 255.255.252.0 summary-only
Answer: D
Explanation:
When the aggregate-address command is used within BGP routing, the aggregated address is advertised, along with the more specific routes.
The exception to this rule is through the use of the summary-only command. The "summary-only" keyword suppresses the more specific routes and announces only the summarized route.

Without this command, a message may pop up and you may not know what you typed if that message is too long. When trying to erase (backspace) your command, you realize you are erasing the message instead.
With this command enabled, when a message pops up you will be put to a new line with your typing command which is very

NEW QUESTION 187
After some changes in the routing policy, it is noticed that the router in AS 45123 is being used as a transit AS router for several service provides. Which configuration ensures that the branch router in AS 45123 advertises only the local networks to all SP neighbors?
A)
B)
C)
D)
- A. Option C
- B. Option B
- C. Option A
- D. Option D
Answer: D
Explanation:
Explanation
By default BGP advertises all prefixes to external BGP neighbors. This means that if you are multi-homed (connected to two or more ISPs) then you might become a transit AS. For example, ISP 2 in AS 200 can send traffic to your router in AS 100 to reach ISP 3 in AS 300 because you advertised prefixes in ISP 3 to ISP 2.
This is what will be seen in the BGP routing table of ISP1:
