ip ecmp-deterministic e Deterministic ECMP Next Hop arranges all ECMPs in order before writing them into the CAM. For example, suppose the RTM learns 8 ECMPs in the order that the protocols and interfaces came up. In this case, the FIB and CAM sort them so that the ECMPs are always arranged.This implementation ensures that every chassis having the same prefixes orders the ECMPs the same. With 8 or less ECMPs, the ordering is lexicographic and deterministic. With more than 8 ECMPs, ordering is deterministic, but it is not in lexicographic order. Syntax Defaults ip ecmp-deterministic Disabled Command Modes CONFIGURATION Command History Usage Information Version 8.3.1.0 Introduced on E-Series. After enabling IPv6 Deterministic ECMP, traffic loss occurs for a few milliseconds while FTOS sorts the CAM entries. ipv6 ecmp-deterministic e Deterministic ECMP Next Hop arranges all ECMPs in order before writing them into the CAM.
