The num parameter specifies the instance of the route map defined in the route-map context that the
CLI enters. Routes are compared to the instances in ascending numerical order. For example, a route is
compared to instance 1, then instance 2, and so on.
Syntax: [no] continue [ instance-number ]
The continue command is entered in the context of a route-map instance. The no form of the
command deletes the continue clause specified by instance-number . The instance number range is 0 -
4294967295, and the occurrences of instance-number must be in ascending numeric order. If you
specify a continue clause without an instance number, it means "continue to the next route-map
instance."
Syntax: [no] neighbor ip-addr | peer-group-name [ route-map in | out map-name ]
This syntax shows only the neighbor parameters that apply to this example. The ip-addr or peer-group-
name identifies the neighbor, and the route-map in and outmap-name options let you specify a route
map and direction to apply to the neighbor.
Dynamic route filter update
Routing protocols use various route filters to control the distribution of routes. Route filters are used to
filter routes received from and advertised to other devices. Protocols also use route-map policies to
control route redistribution from other routing protocols. In addition, route filter policies are used to
select routes to be installed in the routing tables, and used by forwarding engine to forward traffic.
There are currently 5 different types of route filters defined for use in a device:
• Access List (ACL)
• Prefix-List
• BGP4 as-path Access-list
• BGP4 community-list
• Route-map
Not every protocol uses all of these route filters. A protocol will usually use two or three filter types.
