To redistribute OSPF internal routes into BGP for connecting an on-premises network to a cloud provider, the engineer should run the commands “router bgp 100” and “redistribute ospf 1” on router R2. The command “router bgp 100” is used to create a BGP routing process with AS number 100. The command “redistribute ospf 1” is used to redistribute OSPF routes from process ID 1 into BGP. References: = I need to access the specific content of Designing and Implementing Cloud Connectivity (ENCC) v1.0 from Cisco’s official resources to provide exact references. However, I don’t have direct access to external databases or resources, including the Cisco ENCC course materials. I recommend referring to the ENCC course materials for the most accurate and detailed information.

Always refer to the official course materials for the most accurate information.

• To configure a custom application with Cisco SD-WAN centralized policy, you need to follow these steps25:

The process of configuring a custom application with a Cisco SD-WAN centralized policy using Cisco vManage involves several steps1.

• Click Configuration, select Policies, and then select Centralized Policy: This is the first step where you navigate to the Policies section in the Configuration menu of Cisco vManage1.
• Click Custom Options, select Centralized Policy, and then select Lists: In this step, you select the Custom Options, then select Centralized Policy, and finally select Lists1.
• Click Custom Applications, and then select New Custom Application: After setting up the Lists, you click on Custom Applications and then select New Custom Application1.
• Enter a name for the application, enter the match criteria, and then click Add: Finally, you enter a name for the application, specify the match criteria, and then click Add to complete the configuration1.

The command redistribute ospf 1 match external is missing on router R2. This command is needed to redistribute only the external OSPF routes into BGP. The external OSPF routes are those that are learned from another routing protocol or redistributed into OSPF. In this case, the 10.0.10.0/24 network is an external OSPF route, as it is redistributed from EIGRP into OSPF on router R1. The other commands are either already present or not relevant for this scenario. References :=

Step 1 = Click Configuration, select Templates, and then select Feature Templates. Step 2 = Click Add Template, select the device, and then click Select Template. Step 3 = Click CLI Add-On Template and enter the name and description. Step 4 = Paste the CLI configuration and then click Save.

The process of configuring a CLI add-on feature template in Cisco vManage for enhanced policy-based routing (ePBR) for IPv4 involves several steps1234.

• Click Configuration, select Templates, and then select Feature Templates: This is the first step where you navigate to the Templates section in the Configuration menu of Cisco vManage1.
• Click Add Template, select the device, and then click Select Template: In this step, you add a new template for the device1.
• Click CLI Add-On Template and enter the name and description: After setting up the template, you select the CLI Add-On Template option, and then enter the name and description for the template1.
• Paste the CLI configuration and then click Save: Finally, you paste the CLI configuration into the template and save the changes1.

Enhanced Policy-Based Routing (ePBR) is used to direct packets that arrive at an interface to a specified next-hop. It is very useful in managing a large number of configured access lists more efficiently. In ePBR, the router drops the traffic packets if the next hop configured in the PBR policy is not reachable. To avoid packet loss in such scenarios, you must configure multiple next hops for each access control entry.

Here are the steps to configure ePBR for IPv4 using Cisco vManage:

• Configure an extended ACL: This step involves defining the network or the host. For example, you can permit IPv4 traffic from any source to specific hosts.
• Configure a class map that matches the ACL: Class maps match the parameters in the ACLs. For instance, you can create a class map of type traffic and match it with the previously created ACL.
• Configure the policy map with the action to set the next hop: Policy maps with ePBR then take detailed actions based on the set statements configured. You can configure an ePBR policy map with the class map and set the next hop.
• Apply the service policy on the interface: Finally, you apply the ePBR policy map to the interface. For example, you can apply the policy map to a GigabitEthernet interface.

The process of configuring a Cisco SD-WAN Cloud Interconnect with Equinix involves several steps.

• Ensure that you have UUIDs for the required number of Cisco SD WAN Virtual Edge instances that you want to deploy as Interconnect Gateways: This is the first step where you ensure that you have the necessary UUIDs for the Cisco SD-WAN Virtual Edge instances that you want to deploy.
• Create the necessary network segments: After ensuring the availability of UUIDs, you create the necessary network segments.
• Attach Cisco SD-WAN Virtual Edge to the Equinix device template: After setting up the network segments, you attach the Cisco SD-WAN Virtual Edge to the Equinix device template.
• Create the Interconnect Gateway at the Equinix location that is closest to your SD-WAN branch location: Finally, you create the Interconnect Gateway at the Equinix location that is closest to your SD-WAN branch location.
