To deploy three layer 2 overlay-backed segments and one layer 2 VLAN-backed segment, you need to follow these steps:

• Log in to the NSX Manager UI with admin credentials. The default URL is https://.
• Navigate to Networking > Segments and click Add Segment.
• Enter a name for the segment, such as Web-01.
• Select Tier-1 as the connectivity option and choose an existing tier-1 gateway from the drop-down menu or create a new one by clicking New Tier-1 Gateway.
• Enter the gateway IP address of the subnet in a CIDR format, such as 192.168.10.1/24.
• Select an overlay transport zone from the drop-down menu, such as Overlay-TZ.
• Optionally, you can configure advanced settings such as DHCP, Metadata Proxy, MAC Discovery, or QoS for the segment by clicking Set Advanced Configs.
• Click Save to create the segment.
• Repeat steps 2 to 8 for the other two overlay-backed segments, such as App-01 and DB-01, with different subnet addresses, such as 192.168.20.1/24 and 192.168.30.1/24.
• To create a VLAN-backed segment, click Add Segment again and enter a name for the segment, such as Legacy-01.
• Select Tier-0 as the connectivity option and choose an existing tier-0 gateway from the drop-down menu or create a new one by clicking New Tier-0 Gateway.
• Enter the gateway IP address of the subnet in a CIDR format, such as 10.10.10.1/24.
• Select a VLAN transport zone from the drop-down menu, such as VLAN-TZ, and enter the VLAN ID for the segment, such as 100.
• Optionally, you can configure advanced settings such as DHCP, Metadata Proxy, MAC Discovery, or QoS for the segment by clicking Set Advanced Configs.
• Click Save to create the segment.
• To apply a segment security profile to block DHCP requests on the segments, navigate to Networking > Segments > Segment Profiles and click Add Segment Profile.
• Select Segment Security as the profile type and enter a name and an optional description for the profile.
• Toggle the Server Block and Server Block - IPv6 buttons to enable DHCP filtering for both IPv4 and IPv6 traffic on the segments that use this profile.
• Click Save to create the profile.
• Navigate to Networking > Segments and select the segments that you want to apply the profile to.
• Click Actions > Apply Profile and select the segment security profile that you created in step 18.
• Click Apply to apply the profile to the selected segments.

You have successfully deployed three layer 2 overlay-backed segments and one layer 2 VLAN-backed segment with DHCP filtering using NSX-T Manager UI.

To troubleshoot the bridge configuration and restore access to the application, you need to follow these steps:

• Log in to the NSX Manager UI with admin credentials. The default URL is https://.
• Navigate to Networking > Segments and select the overlay segment that is bridged to the VLAN-backed port group. For example, select Web-01 segment that you created in Task 2.
• Click Bridge > Set and verify the configuration details of the bridge. Check for any discrepancies or errors in the parameters such as bridge name, bridge ID, VLAN ID, edge node, etc.
• If you find any configuration errors, click Edit and modify the parameters accordingly. Click Save to apply the changes.
• If you do not find any configuration errors, check the connectivity and firewall rules between the overlay segment and the VLAN-backed port group. You can use ping or traceroute commands from the NSX Edge CLI or the vSphere Web Client to test the connectivity. You can also use show service bridge command to check the status of the bridge service on the NSX Edge.
• If you find any connectivity or firewall issues, resolve them by adjusting the network settings or firewall rules on the NSX Edge or the vSphere Distributed Switch.
• After resolving the issues, verify that the bridge is functioning and the Bridge-VM is responding to ICMP requests from the main console.You can also check the MAC addresses learned by the bridge on both sides of the network using show service bridge mac command on the NSX Edge CLI.

To troubleshoot the NSX IPSec VPN service that has been reported down, you need to follow these steps:

• Log in to the NSX Manager UI with admin credentials. The default URL is https://.
• Navigate to Networking > VPN > IPSec VPN and select the IPSec VPN session that is down. You can identify the session by its name, local endpoint, remote endpoint, and status.
• Click Show IPSec Statistics and view the details of the IPSec VPN session failure. You can see the error message, the tunnel state, the IKE and ESP status, and the statistics of the traffic sent and received.
• Compare the configuration details of the IPSec VPN session with the expected configuration as provided below. Check for any discrepancies or errors in the parameters such as local and remote endpoints, local and remote networks, IKE and ESP profiles, etc.
• If you find any configuration errors, click Actions > Edit and modify the parameters accordingly. Click Save to apply the changes.
• If you do not find any configuration errors, check the connectivity and firewall rules between the local and remote endpoints. You can use ping or traceroute commands from the NSX Edge CLI to test the connectivity. You can also use show service ipsec command to check the status of IPSec VPN service on the NSX Edge.
• If you find any connectivity or firewall issues, resolve them by adjusting the network settings or firewall rules on the NSX Edge or the third-party device.
• After resolving the issues, verify that the IPSec VPN session is up and running by refreshing the IPSec VPN page on the NSX Manager UI. You can also use show service ipsec sp and show service ipsec sa commands on the NSX Edge CLI to check the status of security policy and security association for the IPSec VPN session.
