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.
In a "third party next hop" network where the two IPv6 EBGP peers reside in a common broadcast
subnet, the router does not change the next hop for routes sent to the IPv6 EBGP peer or peer group
by default, unless the peer next-hop-local command is configured.
