If BGP load balancing is configured forequal-cost routes, the local router specifies itself as the next hop of routes sent to an IPv6 iBGP peer orpeer group regardless of whether the peer next-hop-local command is configured.• In a third party next hop network, that is, the two IPv6 eBGP peers reside in a common broadcastsubnet, the router does not specify itself as the next hop for routes sent to the IPv6 eBGP peer or peergroup by default, unless the peer next-hop-local command is configured.Configuring the MED attributeTo do… Use the command… RemarksStep 1 Enter system view system-view —Step 2 Enter BGP view bgp as-number RequiredStep 3 Enter IPv6 address familyview ipv6-family —
