FD 100/320Gbps NT and FX NT IHub Services Guide Virtual Private Routed Network ServiceIssue: 13 3HH-11985-AAAA-TQZZA 4697.10.3.2 addressDescription This command creates a logical IP routing interface for an Virtual Private Routed Network(VPRN). Once created, attributes like an IP address and service access point (SAP) can beassociated with the IP interface.The interface command, under the context of services, is used to create and maintain IProuting interfaces within VPRN service IDs. The interface command can be executed in thecontext of an VPRN service ID. The IP interface created is associated with the service corenetwork routing instance and default routing table. The typical use for IP interfaces created inthis manner is for subscriber internet access.Interface names are case sensitive and must be unique within the group of defined IPinterfaces defined for configure router interface and configure service vprn interface (that is,the network core router instance). Interface names must not be in the dotted decimal notationof an IP address. For example, the name “1.1.1.1” is not allowed, but “int-1.1.1.1” is allowed.Show commands for router interfaces use either interface names or the IP addresses. Useunique IP address values and IP address names to maintain clarity. It could be unclear to theuser if the same IP address and IP address name values are used. Although notrecommended, duplicate interface names can exist in different router instances.The available IP address space for local subnets and routes is controlled with the configurerouter service-prefix command. The service-prefix command administers the allowedsubnets that can be defined on VPRN IP interfaces. It also controls the prefixes that may belearned or statically defined with the VPRN IP interface as the egress interface. This allowssegmenting the IP address space into configure router and configure service domains.When a new name is entered, a new logical router interface is created. When an existinginterface name is entered, the user enters the router interfac context for editing andconfiguration. By default, there are no default IP interface names defined within the system. AllVPRN IP interfaces must be explicitly defined. Interfaces are created in an enabled state.The no form of this command removes IP the interface and all the associated configuration.The interface must be administratively shutdown before issuing the no interface command.For VPRN services, the IP interface must be shutdown before the SAP on that interface maybe removed. VPRN services do not have the shutdown command in the SAP CLI context.VPRN service SAPs rely on the interface status to enable and disable them.Parameters ip-int-name — Specifies the name of the IP interface. Interface names must be unique withinthe group of defined IP interfaces for configure router interface and configure service vprninterface commands. An interface name cannot be in the form of an IP address. Interfacenames can be from 1 to 32 alphanumeric characters. If the string contains special characters(#, $, spaces, etc.), the entire string must be enclosed within double quotes.If ip-int-name already exists within the service ID, the context will be changed to maintain thatIP interface. If ip-int-name already exists within another service ID or is an IP interface definedwithin the configure router commands, an error will occur and context will not be changed tothat IP interface. If ip-int-name does not exist, the interface is created and context is changedto that interface for further command processing.tunnel — Keyword that specifies that the interface is of the type gre tunnel.Item Description(2 of 2)
