Right, especially if there are many dots in the regexp.

If there are dots, try to escape them (e.g. "| include 192\.0\.2\.").
But the output volume of "show ip cache flow" is probably also
significantly larger than the output of "show ip bgp".

On the Catalyst 6500 platform, there are handy option for the equivalent
of "show ip cache flow" to narrow the output to certain
source/destination subnets or UDP/TCP port numbers.  That is more
efficient than having the router convert the entire Netflow table to
text and then filtering 99.9% of the text away by regexp.  Does the
ASR1k software have these kinds of options?
