Exhibit
Which prefix in the output shown in the exhibit is an external prefix injected by an OSPF router?
- A. 192.108.1.4
- B. 172.26.4.0730
- C. 172.18.1.0/24
- D. 192.168.1.3
Answer: C
Explanation:
In the OSPF routing table output, prefixes are marked with different route types. An external prefix injected into OSPF is marked as 'Ext' (External) followed by a number that indicates whether it's an E1 or E2 route.
The prefix 172.18.1.0/24 is marked as Ext2, which indicates that it is an external route that has been redistributed into OSPF from another routing protocol or static configuration.

Exhibit
You have configured graceful RE switchover (GRES), however you cannot complete the show system switchover command.
Referring to the exhibit, what is the problem?

- C. The command is only available if non-stop routing is enabled.
- D. The command is only available If graceful restart is enabled.
Answer: C
Explanation:
Theshow system switchovercommand is used to display the status of the Graceful Routing Engine Switchover (GRES) feature. This command is available when nonstop routing (NSR) is enabled, which works in conjunction with GRES to maintain uninterrupted routing in case of a Routing Engine switchover.

BGP Attribute Categories
There are four categories of BGP attributes:
Well-known mandatory:Recognized by all BGP peers, passed to all peers, and present in all Update messages. Well-known mandatory attributes include:- Next-hop- Origin- AS PATH Well-known discretionary:Recognized by all routers, passed to all peers, and optionally included in the Update message. Well-known discretionary attributes include:- Local Preference- Atomic Aggregate Optional transitive:Possibly recognized by BGP routers and passed to BGP peers. Optional transitive attributes are marked as partial when not recognized. Optional transitive attributes include:- Aggregator- Community Optional non-transitive:Possibly recognized by BGP routers but not passed to peers.

NEW QUESTION # 56
You want to share routes between two routing instances that you have configured?
What are two ways to accomplish this task? (Choose two.)
- A. Use a non-forwarding instance.
- B. Use a RIB group.
- C. Create a forwarding instance.
- D. Configure an instance import policy
Answer: B,D
Explanation:
static route with a next-hop of next-table pointing to the appropriate routing table which contains more accurate information rib-groups to mirror routing information from one route-table to another. However, in many cases, in order to make this work, interface-routes also need to be mirrored. RIB Group policy can be used to constrain the routing information instance-import and instance-export statements configured within the individual routing-instances to leak routes from one table to another. Again, policy can be used here to constrain the routing information. This method is more straightforward than the rib-group method A final approach is to use physical interfaces or logical-tunnels to stitch routing-instances and use a routing protocol or static routes across this connection between the two routing-instances.
To share routes between two routing instances on a Junos device, you can configure an instance import policy in one or both instances to import routes from the other instance. Alternatively, a RIB (Routing Information Base) group can be used to share routes between instances.References:
