Pass Cisco Implementing Cisco Service Provider Advanced Routing Solutions PDF Dumps | Recently Updated 304 Questions
Cisco 300-510 certification exam is ideal for network engineers, network administrators, network designers, and technical support personnel who work in a service provider environment. 300-510 exam tests the candidates' ability to configure, implement, and troubleshoot various routing protocols and services, including OSPF, IS-IS, BGP, MPLS, Layer 3 VPNs, and multicast routing. 300-510 exam also covers topics such as routing policy and route manipulation, as well as high availability and network security.
Cisco 300-510 exam covers a wide range of advanced routing technologies, including Border Gateway Protocol (BGP), Multiprotocol Label Switching (MPLS), and Virtual Private Network (VPN) technologies. It also tests the candidate's knowledge of advanced routing policies, route redistribution, and route filtering techniques. Successful candidates are expected to have a deep understanding of how these technologies work and how they can be configured and optimized in a service provider network.

Topology
Tasks
Star Technology has decided to establish connectivity with an ISP for accessing the Internet. In phase 1, the approach is to establish a dual-homed connection from HQ-R1 to ISP-R1 and ISP- R2. This will provide some degree of redundancy in the connectivity between HQ-R1 and ISP routers.
Based on network design, an autonomous system of Star Technology is 1, and AS of ISP is 2. A network Implementation Engineer has already initiated the configuration; trouble-shooting is required to find out and complete missing configurations. Moreover, configuration is to be established in a way that links between HQ-R1 and ISP-R1 can be used as the preferred path for reaching AS 2.
Below are tasks to be achieved to include the missing commands and complete the troubleshooting Task 1:
On HQ-R1, configure BGP for Autonomous System 1. Establish EBGP relationship with ISP-R1 and ISP-R2.
Notes:
After performing troubleshooting at HQ-R1, the following outcome should appear.
%BGP-5-ADJCHANGE: neighbor 192.168.12.2 Up
%BGP-5-ADJCHANGE: neighbor 192.168.13.2 Up
Task 2:
On HQ-R1, Advertise LBO interface as a prefix in BGR
Task 3:
On HQ-R1, configure the route map with the name loc. Set the local preference attribute as 900.
Task 4:
On HQ-R1, define the path between HQ-R1 - ISP-R1 as the preferred path for reaching AS 2.
Route map configured in task 3 to be used in the inbound direction.
Answer:
Explanation:
Task 1: Configure BGP for AS 1 and Establish EBGP Peering with ISP-R1 and ISP-R2 To establish an EBGP relationship between HQ-R1 and ISP-R1/ISP-R2 on HQ-R1:
router bgp 1
neighbor 192.168.12.2 remote-as 2
neighbor 192.168.13.2 remote-as 2
router bgp 1: Enables BGP for AS 1 on HQ-R1.
neighbor <IP> remote-as 2: Establishes an EBGP session with the neighbors ISP-R1 (192.168.12.2) and ISP-R2 (192.168.13.2).
Task 2: Advertise Loopback0 Interface Prefix in BGP
To advertise the loopback interface (e.g., Loopback0) into BGP on HQ-R1:
router bgp 1
network <L0 IP> mask <L0 Subnet>
Example (assuming Loopback0 IP is 192.168.10.1/24):
router bgp 1
network 192.168.10.0 mask 255.255.255.0
The networkcommand specifies which prefix (L0) to advertise into BGP.
Task 3: Configure a Route Map Named locto Set Local Preference to 900
To set the local preference attribute to 900 using a route map on HQ-R1:
route-map loc permit 10
set local-preference 900
route-map loc permit 10: Creates a route map named loc.
set local-preference 900: Sets the local preference to 900, which influences route selection.
Task 4: Prefer the Path via ISP-R1 for Reaching AS 2
To prefer the link between HQ-R1 and ISP-R1 as the preferred path on HQ-R1:
router bgp 1
neighbor 192.168.12.2 route-map loc in
neighbor 192.168.12.2 route-map loc in: Applies the locroute map inbound on the session with ISP-R1 (192.168.12.2).
This sets the local preference to 900 for routes received from ISP-R1, making it the preferred path.
Verification Commands
Verify BGP Neighbors: show ip bgp summary
Expected output: Neighbors 192.168.12.2and 192.168.13.2should be Up.
Verify Advertised Routes: show ip bgp
Confirm the Loopback0 prefix is advertised.
Verify Local Preference: show ip bgp neighbors 192.168.12.2 received-routes
Check that the local preference is 900 for routes from ISP-R1.
Complete Configuration Summary on HQ-R1:
router bgp 1
neighbor 192.168.12.2 remote-as 2
neighbor 192.168.13.2 remote-as 2
network 192.168.10.0 mask 255.255.255.0
neighbor 192.168.12.2 route-map loc in
route-map loc permit 10
set local-preference 900
The local preference value of 900 ensures that routes from ISP-R1 are preferred over ISP-R2.
The Loopback0 prefix is successfully advertised into BGP.
The BGP sessions to ISP-R1 and ISP-R2 are established as required.
