NOTE:
IPv6 BGP advertises routes passing the specified policy to peers. Using the
protocol argument can filter
only the routes redistributed from the specified protocol. If no
protocol is specified, IPv6 BGP filters all
routes to be advertised, including redistributed routes and routes imported with the network command.
939BConfiguring inbound route filtering
Only routes passing the configured filtering can be added into the local IPv6 BGP routing table.
Members of a peer group can have different inbound route filtering policies.
To configure inbound route filtering:

1255. Configure inbound
route filtering.
filter-policy { acl6-number |
ipv6-prefix ipv6-prefix-name }
import
Not configured by default.
1256. Apply a routing policy
to routes from an IPv6 peer or
peer group.
peer { ipv6-group-name |
ipv6-address } route-policy
route-policy-name import
Not applied by default.
The IPv6 BGP-VPN instance view
does not support the
ipv6-group-name argument.
1257. Specify an ACL to filter
routes imported from an IPv6
peer or peer group.
peer { ipv6-group-name |
ipv6-address } filter-policy
acl6-number import
Not specified by default.
The IPv6 BGP-VPN instance view
does not support this command.
1258. Specify an AS path list
to filter routing information
imported from an IPv6 peer or
peer group.
peer { ipv6-group-name |
ipv6-address } as-path-acl
as-path-acl-number import
Not specified by default.
The IPv6 BGP-VPN instance view
does not support this command.
1259. Specify an IPv6 prefix
list to filter routing information
imported from an IPv6 peer or
peer group.
peer { ipv6-group-name |
ipv6-address } ipv6-prefix
ipv6-prefix-name import
Not specified by default.
The IPv6 BGP-VPN instance view
does not support this command.
1260. Specify the upper limit
of prefixes allowed to receive
from an IPv6 peer or peer
group.
peer { ipv6-group-name |
ipv6-address } route-limit limit
[ percentage ]
Optional.
Unlimited by default.
The IPv6 BGP-VPN instance view
does not support this command.
940BConfiguring 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
