Step Command

Remarks

4.

Configure inbound route

filtering.

filter-policy { acl6-number |
ipv6-prefix ipv6-prefix-name }
import

Not configured by default.

5.

Apply a routing policy to
routes from an IPv6 peer/peer

group.

peer { ipv6-group-name |
ipv6-address } route-policy

route-policy-name import

Not applied by default.

6.

Specify an ACL to filter routes
imported from an IPv6

peer/peer group.

peer { ipv6-group-name |
ipv6-address } filter-policy

acl6-number import

Not specified by default.

7.

Specify an AS path ACL to
filter routing information

imported from an IPv6

peer/peer group.

peer { ipv6-group-name |
ipv6-address } as-path-acl

as-path-acl-number import

Not specified by default.

8.

Specify an IPv6 prefix list to
filter routing information

imported from an IPv6
peer/peer group.

peer { ipv6-group-name |
ipv6-address } ipv6-prefix
ipv6-prefix-name import

Not specified by default.

9.

Specify the upper limit of

prefixes allowed to receive
from an IPv6 peer/peer

group.

peer { ipv6-group-name |
ipv6-address
} route-limit limit

[ percentage ]

Optional.
Unlimited by default.

NOTE:

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.

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:
