Which two routing protocols allow for unequal cost load balancing? (Choose two.)
Which two routing protocols allow for unequal cost load balancing? (Choose two.)
EIGRP (Enhanced Interior Gateway Routing Protocol) and BGP (Border Gateway Protocol) are the two routing protocols that allow for unequal cost load balancing. EIGRP can configure unequal cost paths using the 'variance' command, allowing traffic to be distributed over multiple paths that do not have the same cost. BGP can also support load balancing over multiple paths with different metrics through the implementation of the 'maximum-paths' command. Therefore, they are both capable of unequal cost load balancing.
Is Unequal Cost Multipath (UCMP) different than unequal cost load balancing? Is there a chance IS-IS could be one of the answers? https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/seg_routing/configuration/xe-17/segrt-xe-17-book/m_isis_ucmp.pdf
A,C is correct
unequal-cost load balancing on Cisco routers are IGRP, EIGRP and BGP.
OSPF supports UCMP - https://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/710x/routing/configuration/guide/b-routing-cg-asr9000-710x/implementing-ospf.html#concept_1C8B0FDD4C01402794D3972072C0F6CB
