For example, the value of 2 means that 2 equal cost routes will be used for costsharing.ECMP groups form when the system routes to the same destination with equal cost values.Routing table entries can be entered manually (as static routes), or they can be formed whenneighbors are discovered and routing table informationis exchanged by routing protocols. Thesystem can balance traffic across the groups with equal costs.ECMP can only be used for routes learned with the same preference and same protocol. Seethe discussion on preferences in the static-route command.When more ECMP routes are available at the best preference than configured by themax-ecmp-routes parameter, then the lowest next-hop IP address algorithm is used to selectthe number of routes configured.The no form of the command disables ECMP path sharing. If ECMP is disabled and multipleroutes are available at the best preference and equal cost, then the route with the lowestnext-hop IP address is used.Default No ecmpParameters max-ecmp-routes — IntegerValues: 1 — 8Item DescriptionSyntax maximum-ipv6-routes number [log-only] [threshold percentage]no maximum-ipv6-routesContext configure>service>vprn(1 of 2)
