There are 2 regular expression engines the "default" and a "new" engine that can process complex regular expressions.
Default Regular Expression Engine
- Uses recursive algorithm
- As the complexity of regular expressions increases the more system resources are required
- Works well for simple regular expressions
New Regular Expression Engine Selection
- new engine does not replace the default regular expression engine
- improved algorithm
- greatly improved performance when processing complex regular expressions
- complex regular expressions are evaluated more quickly
- takes longer to process simple regular expressions than the default engine.
Cisco recommends using the regular expression engine that fits your environemnt. New engine for complex regular expressions and default for simple regular expressions.
To enable the New engine type the following under the BGP process.
"bgp regexp deterministic"
To enable the Default engine after enabling the New prefix the command with "no" EX:
"no bgp regexp deterministic"
