NEW QUESTION # 46
Your network is multihomed to two ISPs. The BGP sessions are established; however, the ISP peers are not receiving any routes.
Which two statements are correct about troubleshooting your configuration? (Choose two.)
- A. Verify the import policies on your router.
- B. Verify that the BGP routes are active in your routing table.
- C. Verity that the multihop settings are configured on your router.
- D. Verify the export policies on your router.
Answer: B,D
Explanation:
To troubleshoot why ISP peers are not receiving any routes in a multihomed BGP setup, the following steps are essential:
* Verify Active BGP Routes: Ensure that the BGP routes are active in the routing table. Only active routes can be advertised to BGP peers.
shell
Copy code
show route protocol bgp
* Verify Export Policies: Check the export policies configured on your router. The export policies determine which routes are advertised to BGP peers. If these policies are incorrectly configured or missing, routes will not be advertised.
shell
Copy code
show configuration policy-options policy-statement <policy-name>
show configuration protocols bgp group <group-name> export

NEW QUESTION # 49
You have scheduled maintenance operations for one of the devices in your OSPF network.
Referring to the exhibit, which three statements are correct? (Choose three.)
- A. Any traffic destined for networks that terminate on R1 will still be forwarded to R1.
- B. R1 does not send or receive transit traffic during the maintenance window even if no alternative paths exist to the given destination.
- C. R1 does not participate in OSPF routing.
- D. R1 participates in OSPF routing but does not send or receive transit traffic.
- E. The metrics for all transit interfaces on R1 is set to the maximum value of 65,535.
Answer: A,D,E
Explanation:
- Configure the local routing device so that it appears to be overloaded. You might do this when you want the routing device to participate in OSPF routing, but do not want it to be used for transit traffic. - Traffic destined to directly attached interfaces continues to reach the routing device. - When configured, the transit interface metrics are set to the maximum value of 65535.

You are troubleshooting an EVPN-VXLAN IP fabric and observe the loop shown in the exhibit.
Which two steps would you take to further troubleshoot this problem? (Choose two.)
- A. Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 3 routes are present.
- B. Verify that the same ESI is configured on the two links from the source.
- C. Verify that the same ESI is configured on the link from the host and that it matches the source.
- D. Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 4 routes are present.
Answer: A,D
Explanation:
When troubleshooting an EVPN-VXLAN IP fabric loop, the following steps are crucial:
* Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 4 routes are present: Type 4 routes indicate EVPN Ethernet Segment routes, which are essential for detecting and
* mitigating loops.
* Issue the show route table bgp.evpn.0 command on Leaf2 and verify that Type 3 routes are present: Type 3 routes (Inclusive Multicast Ethernet Tag routes) ensure that multicast and broadcast traffic is properly handled, helping identify and troubleshoot loop issues.
References:
* The commands for verifying BGP EVPN routes are standard in troubleshooting EVPN-VXLAN fabrics.
* Documentation from "Useful Juniper Commands.txt" and "Juniper Commands.pdf" which provide command references for verifying EVPN route types.

For specifying the BGP community attribute only, you also can specify community-ids as one of the following well-known community names defined in RFC 1997:
no-advertise - Routes containing this community name are not advertised to other BGP peers.
no-export - Routes containing this community name are not advertised outside a BGP confederation boundary.
no-export-subconfed - Routes containing this community are advertised to IBGP peers with the same AS number, but not to members of other confederations.
llgr-stale - Adds a community to a long-lived stale route when it is readvertised.
no-llgr - Marks routes which a BGP speaker does not want to be retained by LLGR. The Notification message feature does not have any associated configuration parameters.
