The config for the 2nd repeater will be the same as the first but here is a few things to think about
Repeaters should be the very last design that you ever use only when you have no other options
each repeater hop will halve your throughput
eg
root -------repeater1 ------ repeater 2
If you can have 11Mbps links with minimal interference then the clients on repeater 2 will have only 3 to 4 Mbps half duplex as every pack will be transmitted 3 times you will also find the number of clients will be a lot less.
If the 2nd repeater can see the root at all then it will associate it it and not the 1st repeater.
Any Cisco device will associate to a root at a lower speed in preference to a repeater due to the through put drop
