Actually, I think it was the final sleep n that made it work, not the reduction from 2 to 1. The stdout of your brace expression { ... } was closed before all commands had executed on the router, making it drop the connection.

NAME
inputkill - run a command until standard input is closed SYNOPSIS
inputkill [options] <command> [arguments ...] DESCRIPTION
inputkill runs a given command until standard input is closed. inputkill passes on all file descriptors except for standard input; command is given no standard input. inputkill is useful for promptly exiting a program ran via ssh when the connection is closed. For example, ssh host inputkill sleep 60 runs the command sleep on the computer named host until either sixty seconds elapse or the ssh connection is terminated. The argument "--" disables argument parsing for all proceeding arguments; e.g. "inputkill ls -l" will pass "-l" to inputkill and run "ls", whereas "inputkill -- ls -l" will run "ls -l". OPTIONS
-V, --version Display version information. -?, --help Display a summary of command line options. SEE ALSO
ssh(1), rsh(1) inputkill is part of mswatch(1); mswatch website: http://mswatch.sf.net/ AUTHOR
