Abstract 35 This document describes a management information base for the IS-IS 36 Routing protocol, as described in ISO 10589 [2], when it is used to 37 construct routing tables for IP networks, as described in RFC 1195 38 [3]. 40 This memo defines an experimental portion of the Management 41 Information Base (MIB) for use with network management protocols in 42 the Internet community. 44 This memo is based on an IETF draft by Chris Gunner [1]. This 45 version has been modified to include MIB-II syntax, to exclude 46 portions of the protocol that are not relevant to IP, such as the 47 ES-IS protocol, and to add management support for current practice. 49 3.

Overview 64 This document is provided to the IETF working group on IS-IS. 66 The IS-IS MIB includes of the following objects 68 - isisSystem 70 This table contains information specific to a single instance 71 of the IS-IS protocol running on a router. 73 - isisManAreaAddr 75 This table includes area addresses manualy configured 76 which are used to control the associations formed 77 between Level 1 Intermediate Systems. 79 - isisAreaAddrTable OBJECT-TYPE 81 This table includes area addresses reported by peers. 83 - isisSysProtSuppTable 85 This table includes the manualy configured list of 86 protocols, such as IP or CLNS, supported by the 87 Intermediate System. 89 - isisL2SummAddr 91 This table holds summary addresses configured for each 92 Level 2 instance of the IS-IS protocol running on a 93 router. 95 - isisCirc 97 This table contains information specific to a broadcast or 98 point-to-point interface in the system. 100 - isisCircLevelValues 102 This table contains information specific to a one Level 1 or 103 Level 2 of an interface. 105 - isisCircPDUCounters 107 This table contains information on the number of PDUs of each 108 type sent at a single level in a single direction. 110 - isisISAdj 112 This table contains information about adjacencies to routers 113 maintained by the protocol. Entries in this table cannot be 114 created by management action: they are established through the 115 Hello protocol. 117 - isisISAdjIPAddr 119 This table contains the set of IP Addresses of neighboring 120 Intermediate Systems as reported in received IIH PDUs. 122 - isisReachAddr 124 This table contains information about an address prefix manually 125 configured on the system or learned through another protocol. 127 - isisIPRATable 129 This table contains information about IP reachable address 130 manually configured on this system or learned from another 131 protocol. 133 5.

Security Considerations 2760 Certain management information defined in this MIB may be considered 2761 sensitive in some network environments. 2763 Therefore, authentication of received SNMP requests and controlled 2764 access to management information should be employed in such 2765 environments. 2767 Note that information about authentication types and authentication 2768 keys has been removed from the MIB to increase security. 2770 9.
