ECMP Static Routes

Equal-Cost Multi-Path (ECMP) is a forwarding mechanism that routes packets along multiple paths of equal cost. ECMP provides equally-distributed link load sharing across the paths. The hashing algorithm used is based on the source IP address (SIP). ECMP routes allow the switch to choose between several next hops toward a given destination. The switch performs periodic health checks (ping) on each ECMP gateway. If a gateway fails, it is removed from the routing table, and an SNMP trap is sent.

OSPF Integration

When a dynamic route is added through Open Shortest Path First (OSPF), the switch checks the route’s gateway against the ECMP static routes. If the gateway matches one of the single or ECMP static route destinations, then the OSPF route is added to the list of ECMP static routes. Traffic is load-balanced across all of the available gateways. When the OSPF dynamic route times out, it is deleted from the list of ECMP static routes.

ECMP Route Hashing

You can configure the parameters used to perform ECMP route hashing, as follows:

￿sip: Source IP address (default)

￿dip: Destination IP address

Note – The sip, dip, and dipsip options enabled under ECMP route hashing or in port trunk hashing (portchannel hash) apply to both ECMP and trunk features (the enabled settings are cumulative). If unexpected ECMP route hashing occurs, disable the unwanted source or destination IP address option set in trunk hashing. Likewise, if unexpected trunk hashing occurs, disable any unwanted options set in ECMP route hashing.

￿sport: Source port

￿dport: Destination port

Note – Source port (sport) and/or destination port (dport) options for the ECMP route hash (ip route ecmphash) are supported only when Layer 4 tcpl4 and/or udpl4 options are enabled. Conversely, when tcp14 and/or udpl4 are enabled, hashing options for sport and/or dport must also be enabled.

￿protocol: Layer 3 protocol

￿tcpl4: Layer 4 TCP port

￿udpl4: Layer 4 UDP port

The ECMP hash setting applies to all ECMP routes.
