Introduction This memo defines a 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 the Bootstrap Router (BSR) mechanism for PIM. [I-D.ietf-pim-sm-v2-new], [I-D.ietf-pim-sm-bsr]. This document was created by moving some of the PIM BSR specific MIB tables from one of the earlier version of PIM MIB draft [I-D.ietf- pim-mib-v2]. 2. The Internet-Standard Management Framework For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410[RFC3410]. Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. MIB objects are generally accessed through the Simple Network Management Protocol (SNMP). Objects in the MIB are defined using the mechanisms defined in the Structure of Management Information (SMI). This memo specifies a MIB module that is compliant to the SMIv2, which is described in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 [RFC2580]. 3. Conventions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 4. Overview This MIB module contains four tables. The tables are: 1. The BSR Candidate-RP Table, which contains one row for each multicast group address prefix for which the local router is to advertise itself as a Candidate-RP. 2. The BSR Elected BSR RP-Set Table, which contains one row for each Group-to-RP mapping that was received in C-RP advertisements. Joshi & Bijlani Expires February 24, 2007 [Page 3] Internet-Draft PIM BSR MIB August 2006 3. The BSR Candidate-BSR Table, which contains one row for each Candidate-BSR configuration for the local router. 4. The BSR Elected BSR Table, which contains one row for each elected BSR. This MIB module uses textual conventions defined in the IF-MIB [RFC2863], the INET-ADDRESS-MIB [RFC4001] and the IANA-RTPROTO-MIB. 5.

Security Considerations SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), there is still no control over whom on the secure network is allowed to access (read/change/create/delete) the objects in this MIB module. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. In this MIB module, possible effects that can be induced by SET operations on writable objects include: o A new Candidate BSR with high priority or modification of priority of an existing candidate BSR can takeover the functionality of Elected BSR which can prevent and disrupt the services. o A new Candidate RP with lower priority or modification of priority of an existing Candidate RP can force other routers to select itself for a particular group prefix. This can prevent and Joshi & Bijlani Expires February 24, 2007 [Page 17] Internet-Draft PIM BSR MIB August 2006 disrupt the services provided through this group prefix. The following are the read-write and read-create objects defined in this MIB module: bsrCandidateRPBidir bsrCandidateRPPriority bsrCandidateRPAdvInterval bsrCandidateRPHoldtime bsrCandidateBSRAddressType bsrCandidateBSRAddress bsrCandidateBSRPriority bsrCandidateBSRHashMaskLength Some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. In this MIB module, possible effects that can be induced by GET and/or NOTIFY operations include: o Determination of Elected BSR, Candidate BSRs and Candidate RPs in the Multicast Network topology. This information may be sensitive and may be used in preparation for DoS attacks including any of the attacks described above. SNMP versions prior to SNMPv3 did not include adequate security. Even if the network itself is secure (for example by using IPSec), there is still no control over whom on the secure network is allowed to access (read/change/create/delete) the objects in this MIB module. It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy). Further, deployment of SNMP versions prior to SNMPv3 is NOT RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to enable cryptographic security. It is then a customer/operator responsibility to ensure that the SNMP entity giving access to an instance of this MIB module is properly configured to give access to the objects only to those principals (users) that have legitimate rights to access (read/change/create/delete) them.
