Binds an attachment circuit to a pseudowire, and to configure an
Any Transport over MPLS (AToM) static pseudowire.
• peer-ip-address—IP address of the remote provider edge (PE)
peer. The remote router ID can be any IP address, as long as it
is reachable.
• vc-id—The 32-bit identifier of the virtual circuit (VC) between
the PE routers.
• pw-class—Specifies the pseudowire class for advanced
configuration.
• pw-class-name—Pseudowire class name.
