IP ECMP is supported on all 7210 SAS platforms as described in this document, except those operating in access-uplink mode.
LDP LSR ECMP is supported on all 7210 SAS platforms as described in this document, except those operating in access-uplink mode.
LDP LER ECMP is not supported on any 7210 SAS platforms.
When ECMP is enabled and multiple equal-cost next-hops exit for the IGP route, the packets for this route is sprayed based on hashing routine currently supported for IPv4 packets.
When the preferred RTM entry corresponds to a regular IP route, spraying will be performed across regular IP next-hops for the prefix.
