rsyslog

I have many Cisco / JunOS routers and switches that send logs to my Debian server, which uses rsyslogd.

How can I configure rsyslogd to send these router / switch logs to a specific file, based on their source IP address? I do not want to pollute general system logs with these entries.

For instance:

all routers in Chicago (source ip block: 172.17.25.0/24) to only log to /var/log/net/chicago.
all routers in Dallas (source ip block 172.17.27.0/24) to only log to /var/log/net/dallas.

Finally, these logs should be rotated daily for up to 30 days and compressed.

NOTE: I am answering my own question
