The command used to do manual summarization in RIPng is summary-address.
Step-by-step explanation:
The command used to do manual summarization in RIPng is summary-address. This command allows you to manually summarize routes within a RIPng routing process.
Here is an example of how to use the command:
- Enter the router rip command to enter RIP configuration mode.
- Enter the summary-address command followed by the IPv6 network and prefix that you want to summarize.
- Optionally, you can specify the metric for the summarized route using the metric command.
