prefixes allowed to receive

group.

Configuring IPv6 BGP and IGP route synchronization

By default, upon receiving an IBGP route, an IPv6 BGP router checks the route's next hop. If the next
hop is reachable, the IPv6 BGP router advertises the route to EBGP peers. If the synchronization
feature is configured, in addition to the reachability check of the next hop, the IPv6 BGP router must
find an active IGP route with the same destination network segment before it can advertise the IBGP
route (use the display ipv6 routing-table protocol command to check the IGP route state).
To configure IPv6 BGP and IGP route synchronization:
Step
Enter system view.
1.
Enter BGP view.
2.
Enter IPv6 address family view.
3.
Enable route synchronization
4.
between IPv6 BGP and IGP.

Configuring route dampening

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
