9 – cir_rch
A routing circuit reachable address entity contains information about a manually entered address prefix accessible over that circuit. It exists only on L2 routers and end nodes. On L2 routers the type may be outbound or inbound. A reachable address of type outbound default describes address prefixes in an external domain that are reachable by outbound traffic over this circuit. The routing information contained in the reachable address is entered directly into the L2 decision process. When ManualL2Algorithm has the value routing vector, only reachable addresses with address prefixes corresponding to Phase IV areas are fed into the decision process. An inbound reachable address describes address prefixes corresponding to Phase IV areas which are reachable through the local node by inbound traffic over this circuit. The routing information contained in the reachable address area and cost is entered into a Phase IV routing vector message, which is transmitted periodically over this circuit. On an end system the type may be outbound or for a broadcast circuit only filter. A reachable address of type outbound behaves in a similar way to that on an L2 router except that the routing information is used to control the operation of the ES cache. A reachable address of type filter is used to specify the permitted LAN address of routers on the LAN which will be used by the cache algorithm. The circuit-name refers to the circuit associated with the specified reachable address. The address-prefix refers to the reachable address managed by this command.
