Configuring IPv6 BGP route attributes
This section describes how to use IPv6 BGP route attributes to modify BGP routing policy. The attributes
include the following:
• 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
To ensure an IBGP peer can find the correct next hop, you can 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.
