Changing to new SDM profile

Heimdal#<input>conf t</input>
Enter configuration commands, one per line.  End with CNTL/Z.
Heimdal(config)#<input>sdm prefer dual-ipv4-and-ipv6 default</input>
Changes to the running SDM preferences have been stored, but cannot take effect
until the next reload.
Use 'show sdm prefer' to see what SDM preference is currently active.
Heimdal(config)#<input>exit</input>
Heimdal#<input>reload</input>
