Configuration Roadmap
The configuration roadmap is as follows:
1. Set IP addresses of the inbound and outbound interface of the traffic.
2. Configure static equal-cost routes.
3. Configure ECMP.
4. Configure Switch A to retain the original TTL value.
Data Preparation
To complete the configuration, you need the following data:
l IP addresses of interfaces
l Static routes
