Intercloud Fabric Routing Service provides router functionality that is integrated with Intercloud Fabric. It is created automatically as a container in the Intercloud Fabric Switch, and can be created when an Intercloud Fabric cloud is instantiated or on an existing Intercloud Fabric cloud instance.
Intercloud Fabric Routing Service acts as an edge device in Intercloud Fabric and provides the following functionality:
Inter-VLAN routing for virtual machines in the provider cloud.
The extension of the default gateway from the private cloud to the provider cloud.
The following guidelines and limitations apply to the Intercloud Fabric Routing Service:
Because each Intercloud Fabric cloud requires an IP address for the Intercloud Fabric Routing Service, ensure that the management network has a sufficient number of free IP addresses in its IP pools.
Enabling and configuring the Intercloud Fabric Routing Service involves the following high-level tasks:
Step 1 | Creating an Intercloud Fabric cloud, Intercloud Fabric link, and enabling the Routing Service. |
Step 2 | Creating a virtual data center (VDC) that results in the Routing Service configuration. |
Step 3 | Creating a network that results in the Routing Service configuration.
See Creating Networks. |
Step 4 | Reconfiguring a
Routing Service
instance (perform one of the following tasks):
|
Use this procedure to create an Intercloud Fabric cloud and to enable the Intercloud Fabric Routing Service, which involves defining an Intercloud Fabric cloud and creating an Intercloud Fabric link.
You have installed the Intercloud Fabric components.
You have created a private virtual account.
You have created a public virtual account.
You have the required configurations and hardware to enable a dedicated network connection between the public cloud and AWS VPC using AWS Direct Connect. This prerequisite is required for enabling Direct Connect.
When Direct Connect is enabled, the provider's private IP address that is assigned to the Intercloud Fabric Switch will be used by the Intercloud Fabric components and the Intercloud Fabric Extender to establish a tunnel.

Step 7 | Complete the following fields for Configure Link.
Configuring an Intercloud Fabric link allows you to provide a secure connection between the private cloud and the public cloud. If there is a firewall on the path, ensure that TCP ports 22 and 443 are open for outbound connections. In addition, the firewall should allow UDP port 6644 or 6646 outbound for UDP tunnels, or TCP ports 6644 or 6646 outbound for TCP tunnels. Use HTTPS tunnel mode if only ports 443 and 22 are open.

Step 8 | Complete the following fields for Specify IP Pool.
An IP pool is required for the Intercloud Fabric Extender (ICX) in the public cloud, the Intercloud Fabric Switch (ICS) in the private cloud, and the Routing Service. The maximum number of IP pools specified depends on the deployment type. For standalone type, at least three IP addresses must be available. For HA, at least six IP addresses must be available.
| ||||||||||||||||||||||||||||||||||||||
Step 9 | Complete the following fields for Specify Link Placement.
This is the location where ICX is installed in the private cloud. For HA, we recommend that you use a different host for the secondary ICX.

Step 11 | To view the status of the task, see the Cisco Intercloud Fabric Administration Guide, section "Managing Service Requests." |
A virtual data center (VDC) is a set of resources that is assigned to user groups. An administrator can set polices on the VDCs to control the resources that are used by the user groups. A user group can be associated with many VDCs, catalogs, and policies.
Use this procedure to create a VDC. The creation of a VDC in an Intercloud Fabric cloud automatically results in the configuration of the Routing Service in that Intercloud Fabric cloud.
Note | At least one VDC is required for the Intercloud Fabric cloud to configure the Routing Service. |
Networks in Intercloud Fabric can be local to the cloud, or stretched from the private cloud to the public cloud. In addition to data networks used to connect VMs, Intercloud Fabric requires one management network used by Intercloud Fabric components and an optional transport network. A transport network is required if the routing service is enabled for local routing in the public cloud. The management network can be specified as the transport network. The management or transport network can also be specified as the data network.
Use this procedure to create a network.
