By default, when a BGP router receives an iBGP route, it only checks the reachability of the route’s next
hop before advertisement. If the synchronization feature is configured, only the iBGP route is advertised
by IGP can the route be advertised to eBGP peers.

Configuring IPv6 BGP Route Attributes
This section describes how to use IPv6 BGP route attributes to modify BGP routing policy. These
attributes are:
z
IPv6 BGP protocol preference
z
Default LOCAL_PREF attribute
z
MED attribute
z
NEXT_HOP attribute
z
AS_PATH attribute
Prerequisites
Before configuring this task, you have:
