You can use backticks to quote the terminating string;
you can also stack multiple heredocs.
Here's an example to get the output you show:
#!/usr/bin/env perl
use strict;
use warnings;
my $rule_base = 'ip rule add fwmark 0x0201/0xffff table';
my $route_base = 'ip route add default via 172.27.201.1 dev eth1.201 t
+able';
my @table_nums = (200, 201);
my $routing_commands = <<`RULE` . <<`ROUTE`;
for i in @table_nums; do echo "$rule_base \$i"; done
RULE
for i in @table_nums; do echo "$route_base \$i"; done
ROUTE
print $routing_commands;
Output:
ip rule add fwmark 0x0201/0xffff table 200
ip rule add fwmark 0x0201/0xffff table 201
ip route add default via 172.27.201.1 dev eth1.201 table 200
ip route add default via 172.27.201.1 dev eth1.201 table 201
See "perlop: here-document syntax" for details.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
