Want to summarize with AI?

Modify an existing Cisco Multicloud Defense service VNet to connect it to an Azure Virtual WAN vHub and manage route propagation.

Procedure

	1.	From the Multicloud Defense Controller, navigate to Infrastructure > Gateways > VPCs/VNets.
	2.	Choose a Service VPC that you want to edit, from the list.
	3.	Click Edit.
	4.	In the vWAN Attachment section, set the toggle to Enabled.
	5.	From the vHub drop-down list, choose a hub.
	6.	From the Associated Route Table drop-down list, choose a route table to associate.
	7.	From the Propagate Route Tables drop-down list, choose route tables to propagate.
	8.	To propagate all spoke CIDRs to the vHub, set the toggle to Always. Note To add multiple spoke VPCs to the route tables, use the list builder to move the spoke VPCs from the Available section to the Selected section. Moving the VPC to the Selected section ensures that the VPC is added.
	9.	Click Save. The Service VPC connects to a VWAN containing a vHub and spoke VPCs in Azure. Note that any changes made to route tables are also updated in Azure.
