Which capability is supported by EIGRP but not by OSPF?

EIGRP supports unequal-cost load balancing, allowing traffic to be distributed across multiple paths even if their metrics are different. This is achieved by configuring the variance command, which permits EIGRP to install routes into the routing table that have a metric up to a certain multiple of the best path's metric. OSPF, on the other hand, only supports equal-cost load balancing, meaning it will only use paths with identical metrics to forward traffic. Route filtering and route summarization are capabilities supported by both EIGRP and OSPF. Equal-cost load balancing is also supported by both protocols.
