9.18.6 Example for Configuring Inter-AS 6PE OptionB

This section provides an example of how to configure inter-AS IPv6 Provider Edge (6PE)
OptionB for separate IPv6 networks that connect to different ASs to communicate over an inter-
AS VPN OptionB network.
Networking Requirements
If separate IPv6 networks connect to different ASs, deploy 6PE for the IPv6 networks to
communicate.
In practical application, different inter-AS 6PE solutions are provided for separate IPv6 networks
that connect to multiple ASs, depending on the types of links between the PEs of the ASs. If
inter-AS OptionB public network tunnels are established between PEs, use the inter-AS 6PE
OptionB solution.
As shown in
and PE2. An IPv4 link is established between PE1 and ASBR1, between PE2 and ASBR2, and
between ASBR1 and ASBR2. BGP4+ runs between CE1 and PE1 and between PE2 and CE2.
IBGP runs between PE1 and ASBR1 and between PE2 and ASBR2. EBGP runs between ASBR1
and ASBR2. An MPLS tunnel has been established between PE1 and PE2.
