Command system-view bgp as-number ipv6-family dampening [ half-life-reachable half-life-unreachable reuse suppress ceiling | route-policy route-policy-name ]* Remarks N/A N/A N/A Optional. Not configured by default. Configuring IPv6 BGP route attributes Use the following IPv6 BGP route attributes to modify BGP routing policy: • IPv6 BGP protocol preference • Default LOCAL_PREF attribute • MED attribute • NEXT_HOP attribute • AS_PATH attribute Configuration prerequisites Before you configure IPv6 BGP route attributes, complete the following tasks: • Enable IPv6 function. • Configure IPv6 BGP basic functions. Configuring IPv6 BGP preference and default LOCAL_PREF and NEXT_HOP attributes Follow these guidelines when you configure IPv6 BGP preference and default LOCAL_PREF and NEXT_HOP attributes: • To ensure an IBGP peer can find the correct next hop, configure routes advertised to the IPv6 IBGP peer or peer group to use the local router as the next hop. If BGP load balancing is configured, the local router specifies itself as the next hop of routes sent to an IPv6 IBGP peer or peer group regardless of whether the peer next-hop-local command is configured. 237
