R21xx-HP FlexFabric 11900 MPLS Configuration Guide

190
• Configure basic IPv6 MPLS L3VPN on each AS.
• Configure VPN instances on both PEs and ASBR PEs. The VPN instances on PEs allow CEs to access
the network, and those on ASBR PEs are for access of the peer ASBR PEs.
For more configuration information, see "Configuring MPLS L3VPN."
In the inter-AS IPv6 VPN option A solution, for the same IPv6 VPN, the route targets configured on the PEs
must match those configured on the ASBR-PEs in the same AS to make sure VPN routes sent by the PEs (or
ASBR-PEs) can be received by the ASBR-PEs (or PEs). Route targets configured on the PEs in different ASs
do not have such requirements.
Configuring inter-AS IPv6 VPN option C
To configure inter-AS IPv6 VPN option C, perform proper configurations on PEs and ASBR PEs, and
configure routing policies on the ASBR PEs.
Configuring the PEs
Establish an IBGP peer relationship between a PE and an ASBR PE in an AS, and an MP-EBGP peer
relationship between PEs in different ASs.
The PEs and ASBR PEs in an AS must be able to exchange labeled routes.
To configure a PE for inter-AS IPv6 VPN option C:

Command Remarks
1. Enter system view.
system-view N/A
2. Enter BGP view.
bgp as-number N/A
3. Configure the ASBR PE in the
same AS as an IBGP peer.
peer { group-name | ip-address }
as-number as-number
By default, no BGP peer is
configured.
4. Enter BGP IPv4 unicast
address family view.
ipv6-family [ unicast ] N/A
5. Enable the PE to exchange
BGP IPv4 unicast routes with
the ASBR PE in the same AS.
peer { group-name | ip-address }
enable
By default, the PE does not
exchange BGP IPv4 unicast routes
with any peer.
6. Enable the PE to exchange
labeled routes with the ASBR
PE in the same AS.
peer { group-name | ip-address }
label-route-capability
By default, the PE does not
advertise labeled routes to any
IPv4 peer/peer group.
7. Return to BGP view.
quit N/A
8. Configure the PE of another
AS as the EBGP peer.
peer { group-name | ip-address }
as-number as-number

9. Enter BGP-VPNv6 address
family view.
ipv6-family vpnv6 N/A
10. Enable the PE to exchange
BGP VPNv6 routing
information with the EBGP
peer.
peer ip-address enable
By default, the PE does not
exchange labeled routes with any
IPv4 peer/peer group.
