Describes the interfaces used for attaching services in a service chain to a router and the attachment methods available.
The services in a service chain must be in a single VPN, called a service chain VPN, or SC-VPN.
Summary
The key components involved in attaching services in a service chain to a router are:
-
Cisco Catalyst SD-WAN router: Acts as the attachment point for service chain services
-
Service chain VPN (SC-VPN): Contains all services in the service chain
-
Interface types: Provide various attachment methods including IPv4, IPv6, dual stack, or tunnel interfaces
Workflow
These stages describe how services in a service chain attach to a router through different interface types:
- The services can be attached through any combination of the following interface types:
1
IPv4 attachment
2
IPv6 attachment
3
Dual stack attachment
4
Tunnel attachment
