Configuring IP Prefix Lists
IP prefix lists match the IP packet or route against a list of prefixes and prefix lengths. You can create
an IP prefix list for IPv4 and create an IPv6 prefix list for IPv6.
You can configure the prefix list entry to match the prefix length exactly, or to match any prefix with a
length that matches the configured range of prefix lengths.
Use the ge and lt keywords to create a range of possible prefix lengths. The incoming packet or route
matches the prefix list if the prefix matches and if the prefix length is greater than or equal to the ge
keyword value (if configured) and less than or equal to the lt keyword value (if configured).

Because you can use a route map before you define it, verify that all your route maps exist when you
finish a configuration change.
You can view the route-map usage for redistribution and filtering. Each individual routing protocol
provides a way to display these statistics.
When you redistribute BGP to IGP, iBGP is redistributed as well. To override this behavior, you
must insert an additional deny statement into the route map.
