Configure BGP as illustrated in the topology. Use the Loopback 0 addresses for peering. Do NOT configure any IGPs. Instead, use static routes only. R1 should peer with R2 and R4. R2 should peer with R1 and R3. R3 should peer with R2 and R4. R4 should peer with R1 and R3.

In order to ensure that the ORIGIN code is INCOMPLETE, you need to redistribute the LAN subnets into BGP. However, you can also use the network statement in conjunction with a route map and set the ORIGIN code within the route map.

R1(config)#route-map CONNECTED permit 10

R1(config-route-map)#match interface fastethernet 0/0

R1(config-route-map)#exit

R1(config)#route-map CONNECTED deny 20

R1(config-route-map)#exit

R1(config)#router bgp 1

R1(config-router)#redistribute connected route-map CONNECTED R1(config-router)#exit

You can verify the ORIGIN code by looking at the prefix entry in the BGP Tables. The ORIGIN code of INCOMPLETE is denoted by a question mark (?) in the output of the show ip bgp command. You can view additional detail on a per-prefix basis also when using this command

Configure BGP, so that R4 prefers the path via R3 to reach any subnet

In the output of the show ip bgp command on R4 we can see that the preferred route to reach 150.3.3.0 is via R3, however the preferred route to reach 150.2.2.0 is via R1 (the lowest routerid), also, to ensure that the subnet 150.1.1.0 will be reached via R3, configure BGP on R1 to advertise all prefixes with a longer AS-PATH to influence the path selection as follow:

R1(config)#route-map PREP permit 10

R1(config-route-map)#set as-path prepend 1 1 1 1 R1(config-route-map)#exit

R1(config)#router bgp 1

R1(config-router)#neighbor 4.4.4.4 route-map PREP out R1(config-router)#exit

Notice now the preferred path to reach both prefixes 150.3.3.0 and 150.2.2.0 is via R3 with the next-hop 3.3.3.3 because the shortest AS-PATH length:

Configure R4 so that it sends all updates to R3 with a MED of 4. Configure R2 so that it sends all updates to R3 with a MED of 2. Ensure that R3 prefers all routes with the better (lower) MED value.

Before configuring the MED let's verify the BGP RIBs on R3:

The preferred path to reach the prefix 150.1.1.0 is via R4, we should see all routes with the next-hop R2:

Let's configure MED on R3:

R4(config)#route-map MED permit 10

R4(config-route-map)#set metric 4

R4(config-route-map)#exit

R4(config)#router bgp 4

R4(config-router)#neighbor 3.3.3.3 route-map MED out

R4(config-router)#exit

R2(config)#route-map MED permit 10

R2(config-route-map)#set metric 2

R2(config-route-map)#exit

R2(config)#router bgp 2

R2(config-router)#neighbor 3.3.3.3 route-map MED out

R2(config-router)#exit

Let's verify the BGP RIBs of R3:

We have still the best path to reach 150.1.1.0 via R4 as shown by the show ip bgp command on R3 below, so the problem is not resolved even if R2 advertises the lowest MED comparing with R4.

The reason is: we met two issues in this case:

-the first issue is: by default, the MED is only compared for path received from the same AS ,in this case R3 receives two values of MED from two routers (R2 and R4) configured in different AS.

-The second issue: the MED is compared after the AS-PATH in the BGP decision process. In this case R3 will select the path via R4 as the best path to the 150.1.1.0/24 prefix because of the shorter AS-PATH length.

To override the two issues, configure the bgp always-compare-med command to avoid the first issue so always compare the MED even if MED is received from Different AS. And bgp bestpath as-path ignore command to avoid the second issue so that R3 override the BGP decision process by ignoring the step of the AS-PATH in the BGP Decision Process:

Let's configure these two commands:

R3(config)#router bgp 3

R3(config-router)#bgp bestpath as-path ignore R3(config-router)#bgp always-compare-med

We can see for the prefix 150.1.1.0 that the path with the longer AS-PATH length is preferred because the lowest MED even if the AS-PATH takes precedence over the MED in the order of the path selection in BGP:

Another way to verify all BGP RIBs with do show ip bgp, R3 prefers all routes from R2 because the lowest MED:

MPLS TROUBLESHOOTING TIPS FOR CISCO AND JUNIPER

MPLS TROUBLESHOOTING TIPS FOR CISCO AND JUNIPER

#mpls #cisco #juniper #troubleshooting #huawei #copy #tutorial

Basic MPLS Troubleshooting Tips

1. Verifying MPLS Configuration:

• Cisco:
  • Use show mpls interfaces to verify that MPLS is enabled on the correct interfaces.
  • Check show mpls ldp neighbor to ensure that Label Distribution Protocol (LDP) neighbors are discovered, and that the session is up.
• Juniper:
  • Use show mpls interface to check MPLS status on interfaces.
  • Utilize show mpls ldp session to confirm LDP neighbor sessions.

2. Checking Label Switch Paths (LSP):

• Cisco:
  • Use show mpls ldp bindings to display local and remote label bindings.
  • show mpls forwarding-table helps to inspect the labels being forwarded and their corresponding next-hops.
• Juniper:
  • Use show mpls lsp extensive to get detailed information about the LSPs.
  • show route table mpls.0 to view the label-switched routes.

3. Ensuring Proper Route Distribution:

• Cisco:
  • Verify routing protocols are correctly redistributing routes with show ip route and show ip protocols.
  • Ensure that MPLS labels are being properly assigned by checking show mpls forwarding-table.
• Juniper:
  • Check routing information with show route forwarding-table family mpls.
  • Ensure correct route redistribution settings with show route protocol.

4. Troubleshooting MPLS VPNs:

• Cisco:
  • For issues with VRF (Virtual Routing and Forwarding), use show ip vrf and show ip route vrf [vrf-name].
  • Verify MPLS VPN label distribution and path information using show mpls forwarding-table vrf [vrf-name].
• Juniper:
  • Check VRFs using show route table [vrf-name].inet.0.
  • Look at the VPN labels with show route table [vrf-name].inet.0 detail.

5. Utilizing Cisco debug and Juniper traceoptions:

• Cisco:
  • In-depth troubleshooting can be performed by enabling debugging: debug mpls ldp for LDP-related issues or debug mpls traffic-eng for traffic engineering problems.
• Juniper:
  • Use traceoptions under the MPLS or routing protocol configuration to capture more detailed logs for troubleshooting.

6. Common Pitfalls and Checks:

• Both Cisco and Juniper:
  • Ensure there are no MTU mismatches across MPLS-enabled interfaces, as this can disrupt proper LSP formation.
  • Regularly check for software or firmware updates that address known bugs or add enhancements to MPLS features.

AWS IAM user

 how to give IAM user full access in AWS console.

follow below steps:

•  Login to console.aws.amazon.com using root user.
•  Search IAM on the search bar on the top as shown in figure 1.
•  Click on users in the left menu under access management as shown in figure 2.
• Steps to configure a user are shown in figure 0.
• Click on create user as shown in figure 3 after following figure 2 step.
• After following figure 3, follow figure 4 steps. Define the username, provide access to console, and select we want to create a IAM user.
• For the password we are using an auto generated password and enforcing that user must create a new password after first login as shown in figure 5.
• Set permissions as IAM full access as shown in figure 6.

5G Phased array

 In 5G communication systems, the phased-array antenna is one of the lead front-end components that defines massive multiple-input, multiple-output (MIMO) performance. The trend outlined in recent years involves providing a robust and complete platform/wizard for RF/microwave engineers to develop more capable antennas and other RF front-end components in less time than before.1 In addition, systems that operate at millimeter-wave (mmWave) frequencies offer benefits that include small antenna sizes and more available bandwidth.2

However, a challenge arises due to the wide variety of application-driven requirements, which encompasses everything from both city and rural environments to realized gain, scan, and polarization performance attributes to impedance matching and more. Such an extensive number of requirements cannot be met by a single and one-time designed element. This means that any practically convenient modeling platform must contain an extensive library of predesigned antenna elements.

Unfortunately, 5G antennas belong to a class of relatively small and densely populated phased arrays in which the total number of radiators typically does not exceed several hundred. If it does, the consistency of results obtained through such system-level platforms ultimately depends on the accuracy of the phased-array element models, which should include the relatively strong mutual coupling with other elements in the array (this mutual coupling can be −15 dB or 0.18 V relative to 1-V element excitation and sometimes even higher).

To date, the antenna-array block of numerous platforms avoids the associated challenges by using data from either a single radiator simulation/test in free space (meaning all elements are identical and mutual coupling is ignored) or a low-complexity and memory-consuming Floquet-Bloch technique. The latter assumes that all radiators are set in an infinite array and are thus identical, since each element is mutually coupled with the same infinite number of driven neighbors. We will demonstrate why both approaches have limited accuracy and how to overcome them
