Or you you use '&&'s, they only execute the next statement if the first exits 
successfully.

ifconfig eth0 192.168.0.102 && sleep 100 && ifconfig 192.168.0.101 (orig ip)

if things go wrong sleep exits successfully and the final command is executed. 
If things work out ok just re-ssh to the new ip and kill sleep, which then 
exits with an error code and the final ifconfig won't run.
