Command Remarks
1. Enter system view.
system-view N/A
2. Enter BGP view.
bgp as-number N/A
3. Enter IPv6 BGP-VPN instance
view.

4. Configure the PE as the EBGP
peer.

N/A
5. Redistribute the VPN routes.
import-route protocol [ process-id
[ med med-value | route-policy
route-policy-name ] * ]
By default, No route redistribution
is configured.
6. Configure a filtering policy to
filter the routes to be
advertised.
filter-policy { acl6-number |
ipv6-prefix ip-prefix-name } export
[ direct | isisv6 process-id | ripng
process-id | static ]
Optional.
By default, BGP does not filter the
routes to be advertised.
7. Configure a filtering policy to
filter the received routes.
filter-policy { acl6-number |
ipv6-prefix ip-prefix-name } import
Optional.
By default, BGP does not filter the
received routes.
NOTE:
IPv6 BGP runs within a VPN in the same way as it runs within a public network. For more information
about IPv6 BGP, see
Layer 3—IP Routing Configuration Guide .
Resetting BGP connections
When BGP configuration changes, use the soft reset function or reset BGP connections to make the
changes take effect. Soft reset requires that BGP peers have the route refreshment capability, which
means supporting Route-Refresh messages.
NOTE:
Soft reset of BGP connections refers to updatin
