How to run the following expect commands in a loop

#!/usr/bin/expect
spawn telnet 1.1.1.1
expect login*
send “admin\r”
expect Password*
send “abcdef123\r”
expect “Router#”
send “exit\r”


I want the above code to run in a loop such that script keeps doing a telnet to the device. Please suggest

Just use a while loop

Below example runs 300 times and if a timeout occurs on any of the expected strings it will print a timeout message and stop.

Code:
#!/usr/bin/expect
set times 0;
while { $times < 300 } {
   spawn telnet 1.1.1.1
   expect {
       "login" { send "admin\r"; exp_continue }
       "Password" { send "abcdef123\r"; exp_continue }
       "Router#" { send "exit\r" ; exp_continue }
       eof { }
       timeout { puts "timeout waiting for response" ; close ; exit }
   }
   set times [ expr $times+1];
}
