How do you redistribute a route back into BGP?

To redistribute a route back into BGP, the correct method is to configure the BGP process and then redistribute the appropriate routing protocol into BGP. This allows routes learned through different routing protocols (such as OSPF, EIGRP, or RIP) to be shared and advertised to BGP peers.

When you enter the BGP configuration mode, you can utilize the redistribute command to specify which routing protocol you want to include in BGP's view of the network. This is essential in scenarios where you need to integrate BGP with other routing protocols in a multi-protocol environment, enabling BGP to manage and propagate routes that exist in the other protocols’ routing tables.

The other options do not correctly address the process of redistributing routes into BGP. Simply creating a static route and advertising it does not inherently involve the BGP process or redistribution; it merely introduces a route without integration with other routing protocols. Exiting configuration mode and changing the interface type are unrelated to the redistribution of routes back into BGP and do not contribute to the intended goal of propagating routing information within a BGP environment.
