Configuration Guide - VPN
Procedure
Step 1
4.4 Configuring Basic BGP/MPLS IPv6 VPN
Step 2 Configuring ASBR by considering the peer ASBR as its CE.
Step 3 Configuring an IPv6 VPN instance for the PE and the ASBR separately. For more detail, refer
to 4.3 Configuring an IPv6 VPN
The VPN instance for PE is used to access CE; that for ASBR is used to access its peer ASBR.

Example
Run the display bgp vpnv6 all peer command. If the BGP IPv6 VPN peer relationship between
the ASBR and the PE in the same AS is "Established", it means the configuration succeeds.
Run the display bgp vpnv6 all routing-table command. If the VPN-IPv6 routes of the ASBR
are displayed, it means the configuration succeeds.
Running the display ipv6 routing-table vpn6-instance vpn6-instance-name command, you can
view the relevant IPv6 VPN routes in the VPN routing table of the PE and the ASBR.

4.8 Configuring Inter-AS IPv6 VPN-Option B

In inter-AS IPv6 VPN OptionB, ASBRs exchange VPNv6 routes that are sent from the PEs in
the attached ASs through MP-EBGP.
Issue 01 (2011-07-15)
NOTE
In inter-AS VPN-Option A mode, for the same IPv6 VPN, the VPN targets of the IPv6 VPN instance on
ASBR and the PE must be matched in an AS. This is not required for the PEs in different ASs.
Run the display bgp vpnv6 all peer command to check information about the BGP peers
on the PE or the ASBR.
Run the display bgp vpnv6 all routing-table command to check the VPN-IPv6 routes on
the PE or the ASBR.
Run the display ipv6 routing-table vpn6-instance vpn6-instance-namecommand to check
the VPN routing table on the PE or the ASBR.
