as autonomous_system
Restrict selection of routes to those learned from the specified autonomous system.
tag tag
Restrict selection of routes to those with the specified tag.
aspath aspath_regexp
Restrict selection of routes to those that match the specified AS path.
restrict
Indicates that these routes are not to be considered as contributors of the specified aggregate.
The specified protocol may be any of the protocols supported by GateD.
route_filter
See below.
A route may only contribute to an aggregate route which is more general than itself; it must match the
aggregate under its mask. Any given route may only contribute to one aggregate route, which will be the
most specific configured, but an aggregate route may contribute to a more general aggregate.
Route Filters
All the formats allow route filters as shown below. See the section on route filters for a detailed explana-
tion of how they work. When no route filtering is specified (when restrict is specified on the first line
of a statement), all routes from the specified source will match that statement. If any filters are specified,
only routes that match the specified filters will be considered as contributors. Put differently, if any filters
are specified, an all restrict ; is assumed at the end of the list.

Glossary of Terms
Terms used in descriptions throughout this document are defined below:
adjacency
A relationship formed between selected neighboring routers for the purpose of exchanging routing
information. Not every pair of neighboring routers becomes adjacent.
autonomous system
A set of routers under a single technical administration, using an interior gateway protocol and com-
mon metrics to route packets within the AS, and using an exterior gateway protocol to route packets
to other ASs. Since this classic definition was developed, it has become common for a single AS to
use several interior gateway protocols and sometimes several sets of metrics within an AS. The use
of the term Autonomous System stresses that even when multiple igps and metrics are used, the
administration of an AS appears to other ASs to have a single coherent interior routing plan and
presents a consistent picture of what networks are reachable through it. The AS is represented by a
number between 1 and 65534, assigned by the Internet Assigned Numbers Authority.
BGP
Border Gateway Protocol
One of a class of exterior gateway protocols, described in more detail in the BGP section of the Pro-
tocol Overview.
cost An OSPF metric. See metric.
delay
A HELLO metric. Valid values are from zero to 30000 inclusive. The value of 30000 is the max-
imum metric and means unreachable. See metric.
designated router
OSPF: Each multiaccess network that has at least two attached routers as a designated router. The
designated router generates a link state advertisement for the multiaccess network and assists in
running the protocol. The designated router is elected by the HELLO protocol.
destination
Any network or any host.
