Inter-AS PWE3

In actual network, multiple sites of a VPN of a user may connect with multiple service providers
of different ASs or with multiple ASs of a service provider. The VPN is called inter-AS VPN.

Inter-AS PWE3 has two schemes:

l

Inter-AS PWE3-Option A: Data of an inter-AS user is transmitted through special interfaces
between ASBRs. The user exclusively uses the link between the ASBRs.

l

Inter-AS PWE3-Option C: The PEs advertise the VPN IPv4 routes through multi-hop MP-
EBGP.

The S7700 supports the Inter-AS PWE3-Option A

In Option A, the ASBRs of the two ASs are directly connected. The ASBRs are the PEs of their
respective ASs. The two ASBRs consider the peer ASBRs as their CE devices.
