Step Command Remarks
3. Enter BGP-VPN instance
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.
address-family ipv6 [ 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 advertised routes.
filter-policy { acl6-number |
prefix-list ipv6-prefix-name }
export [ protocol process-id ]
By default, BGP does not filter
advertised 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.
2. Configure the CE:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter BGP view. bgp as-number N/A
3. Configure the PE as an
EBGP peer.
peer { group-name |
ipv6-address } as-number
as-number
By default, no BGP peer is
configured.
4. Create and enter BGP IPv6
unicast address family view. address-family ipv6 [ unicast ]
N/A
5. 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.
6. (Optional.) Configure route
redistribution.
import-route protocol
[ process-id [ med med-value |
route-policy route-policy-name ]
* ]
A CE must advertise its VPN
routes to the connected PE so that
the PE can advertise them to the
peer CE.
Configuring IBGP between a PE and a CE
Use IBGP between PE and CE only in a basic IPv6 MPLS L3VPN network. In networks such as inter-AS
VPN and carrier's carrier, you cannot configure IBGP between PE and CE.
1. Configure the PE:
