2. Enable BGP and enter BGP
view.
bgp as-number N/A
3. Enter BGP-VPN view.
ip vpn-instance vpn-instance-name
N/A
4. Configure the CE as the VPN
EBGP peer.
peer { group-name |
ipv6-address } as-number
as-number
By default, no BGP peer is
configured.
5. Create and enter BGP-VPN
IPv6 unicast address family
view.
ipv6-family [ unicast ]
Configuration commands in
BGP-VPN IPv6 unicast address
family view are the same as those
in BGP IPv6 unicast address family
view. For details, see Layer 3—IP
Routing Configuration Guide.
6. Enable IPv6 unicast route
exchange with the specified
peer or peer group.
peer { group-name | ip-address }
enable
By default, BGP does not exchange
IPv6 unicast routes with any peer.
7. Redistribute the routes of the
local CE.
import-route protocol [ process-id
[ med med-value | route-policy
route-policy-name ] * ]
A PE must redistribute the routes of
the local CE into its VPN routing
table so that it can advertise them
to the peer PE.
8. (Optional.) Configure filtering
of redistributed routes.
filter-policy { acl6-number |
prefix-list ipv6-prefix-name }
export [ protocol process-id ]
By default, BGP does not filter
redistributed routes.
9. (Optional.) Configure filtering
of received routes.
filter-policy { acl6-number |
prefix-list ipv6-prefix-name }
import
By default, the PE does not filter
received routes.
