BGP Route Mapping Rules
At a minimum, every line in a route map must include an Action, a Route,
and a Direction. Together, these components, along with optional input and
output modifiers, specify a rule that the router will follow when a route meets
the condition of the rule.
v
Note: No input routes will be accepted by the router unless a BGP route
map or IP route filter has been defined. To allow all other network numbers
not filtered, include the following rule:
permit 0.0.0.0
Action
These parameters specify the action to be taken when a route meets the condi-
tion of the rule. Select permit or deny.
Route
The Route consists of an IP address with the optional /bits
at the end of the
IP address. IP addresses can be specified in the following three ways.
• Normal dotted-decimal notation. Example 192.168.12.4
• Factorized addresses in the form of #.#.#.# {#,#,...} Example 192.168.12.
{1,4,8} This means IP addresses 192.168.12.1, 192.168.12.4, and
192.168.12.8
