Description (partial)


When multiple EIGRP processes are configured in the same VRF, and these processes use consecutive autonomous-system (AS) numbers, SNMP get-next or get-bulk operations against the cEigrpTraffStatsTable MIB may inadvertenly skip over certain EIGRP processes.
The problem is only seen with consecutive AS numbers. For example, if AS 1,2,3, and 5 are configured, a MIB walk starting from AS 1 will skip AS 2, but will include AS 3 and AS 5. Similarly, a MIB walk starting from AS 2 will skip AS 3 but will include AS 5. The problem also only affects the cEigrpTraffStatsTable MIB; the other EIGRP MIB tables will correctly reflect all EIGRP processes when walked.
