13-12 Frame Relay Module 4.0 User Guide, Rev 01is the IP address of the end-to-end sender. The valid range of values guarantees thatyou cannot configure all 0s or all 1s for a network ID, node ID, or subnet ID. (See page13-1.)Network Maskis used during routing to determine the portion of the address associated with thenetwork and subnetwork (if any). All bits associated with the network/subnet shouldbe set to 1, and must be contiguous.Descriptions of Parameters Specific to X.25 InterfacesDestination IP Addressis the IP address of the end-to-end receiver for point-to-point X.25 connections. Thevalid range of values guarantees that you cannot configure all 0s or all 1s for a networkID, node ID, or subnet ID. (See page 13-1.)Unnumbered Interfaceallows the point-to-point frame relay interface to be configured without specifying asource IP address. If Y, the address of the lowest IP interface number (not the lowestaddress, but the number, in the range 0–256, that identifies the interface) in the FRMis used as a default source IP address. (It does not matter what type that interface is.)All un-numbered interfaces on the FRM use the same default address.If a new interface with a lower number is added, that interface’s address will becomethe new default source IP address, but only after the next IPL of the FRM.Naturally, this feature works only if there is at least one numbered interface in thedevice. If there are none, all un-numbered interfaces remain disabled. Once a num-bered interface is added, all un-numbered interfaces will become active.Source IP Addressis the IP address of the end-to-end sender. The valid range of values guarantees thatyou cannot configure all 0s or all 1s for a network ID, node ID, or subnet ID. (See page13-1.)Network Maskis used during routing to determine the portion of the address associated with thenetwork and subnetwork (if any). All bits associated with the network/subnet shouldbe set to 1, and must be contiguous.Source Subscriberis a subscriber ID associated with the source IP interface port. (The port is the firstRouting Path configured in the SVC Subscriber record.)Destination Subscriberis a subscriber ID associated with the destination IP interface port. (The port is the firstRouting Path configured in the SVC Subscriber record.)SVC Retry Timeris the frequency with which calls will be placed to try to establish an X.25 connection.SVC Idle Timeris a period that IP remains active with no traffic before the X.25 connection is cleared.
