Abstract This memo defines an experimental portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it describes managed objects used for managing IP Multicast Routing for IPv4 and IPv6, independent of the specific multicast routing protocol in use. 2. Introduction This MIB describes objects used for managing IPv4 and IPv6 Multicast Routing[2],independent of the specific multicast routing protocol [3,4,5,6,7] in use. This MIB extends the MIB proposed in [8]. Managed objects specific to particular multicast routing protocols are specified elsewhere. Similarly, this MIB does not support management of multicast routing for other address families. Such management may be supported by other MIBs. 3. The SNMP Management Framework 1 draft-thaler-idmr-multicast-routemib-1 June 2000 The SNMP Management Framework presently consists of five major components: o An overall architecture, described in RFC 2571 [9]. o Mechanisms for describing and naming objects and events for the purpose of management. The first version of this Structure of Management Information (SMI) is called SMIv1 and described in RFC 1155 [10], RFC 1212 [11] and RFC 1215 [12]. The second version, called SMIv2, is described in RFC 2578 [13], RFC 2579 [14] and RFC 2580 [15]. o Message protocols for transferring management information. The first version of the SNMP message protocol is called SNMPv1 and described in RFC 1157 [16]. A second version of the SNMP message protocol, which is not an Internet standards track protocol, is called SNMPv2c and described in RFC 1901 [17] and RFC 1906 [18]. The third version of the message protocol is called SNMPv3 and described in RFC 1906 [18], RFC 2572 [19] and RFC 2574 [20]. o Protocol operations for accessing management information. The first set of protocol operations and associated PDU formats is described in RFC 1157 [16]. A second set of protocol operations and associated PDU formats is described in RFC 1905 [21]. o A set of fundamental applications described in RFC 2573 [22] and the view-based access control mechanism described in RFC 2575 [23]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the mechanisms defined in the SMI. This memo specifies a MIB module that is compliant to the SMIv2. A MIB conforming to the SMIv1 can be produced through the appropriate translations. The resulting translated MIB must be semantically equivalent, except where objects or events are omitted because no translation is possible (use of Counter64). Some machine readable information in SMIv2 will be converted into textual descriptions in SMIv1 during the translation process. However, this loss of machine readable information is not considered to change the semantics of the MIB. 4. Overview This MIB module contains one scalar and five tables. The tables are: Thaler,Adams,Siadak Experimental/Expires Dec 2000 2 draft-thaler-idmr-multicast-routemib-1 June 2000 (1) the Multicast Route Table containing multicast routing information for datagrams sent by particular sources to the multicast groups known to a router. (2) the Multicast Routing Next Hop Table containing information on the next-hops for the routing multicast datagrams. Each entry is one of a list of next-hops on outgoing interfaces for particular qsources sending to a particular multicast group address. (3) the Multicast Routing Interface Table containing multicast routing information specific to interfaces. (4) the Multicast Scope Boundary Table containing the boundaries configured for multicast scopes [24]. (5) the Multicast Scope Name Table containing human-readable names of multicast scope. 5.

IANA Considerations The ipMRouteRtProto, ipMRouteNextHopProtocol, ipMRouteInterfaceProtocol, and ipMRouteProtocol use textual conventions imported from the IANA-RTPROTO-MIB. The purpose of defining these textual conventions in a separate MIB module is to allow additional values to be defined without having to issue a new version of this document. The Internet Assigned Numbers Authority (IANA) is responsible for the assignment of all Internet numbers, including various SNMP- related numbers; it will administer the values associated with these textual conventions. The rules for additions or changes to the IANA-RTPROTO-MIB are outlined in the DESCRIPTION clause associated with its MODULE-IDENTITY statement. The current versions of the IANA-RTPROTO-MIB can be accessed from the IANA home page at: "http://www.iana.org/". 7. Security Considerations This MIB contains readable objects whose values provide information related to multicast routing, including information on what machines are sending to which groups. There are also a number of objects that have a MAX-ACCESS clause of read-write and/or read- create, such as those which allow an administrator to configure multicast boundaries. While unauthorized access to the readable objects is relatively innocuous, unauthorized access to the write-able objects could cause a denial of service, or could cause wider distribution of packets intended only for local distribution. Hence, the support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. SNMPv1 by itself is such an insecure environment. Even if the network itself is secure (for example by using IPSec), even then, there is no control as to who on the secure network is allowed to access and SET (change/create/delete) the objects in this MIB. It is recommended that the implementers consider the security features as provided by the SNMPv3 framework. Specifically, the use of the User-based Security Model RFC 2574 [20] and the View- based Access Control Model RFC 2575 [23] is recommended. It is then a customer/user responsibility to ensure that the SNMP entity giving access to this MIB, is properly configured to give access to those objects only to those principals (users) that have legitimate rights to access them. 8.
