If it's ethernet to Ethernet it is very easy. You are just creating a
tunnel across a network.

Ethernet
Traffic that originates on Ethernet is picked up from the local Ethernet
bridge group and transported across the DLSw+ network. DLSw+ always
transfers data in noncanonical format. In Figure 2-4, you do not need to
configure the left router for translational bridging or worry about what
media resides on the other side of the WAN. DLSw+ will automatically make
the correct MAC address conversion depending on the destination media. When
DLSw+ receives a MAC address from an Ethernet-attached device, it assumes it
is canonical and converts it to noncanonical for transport to the remote
peer. At the remote peer, the address is either passed unchanged to Token
Ring-attached end systems or converted back to canonical if the destination
media is Ethernet. Note that when an SNA resource resides on Ethernet, if
you configure a destination SNA address in that device, you must use
canonical format. For example, Ethernet-attached IBM 3174s must specify the
MAC address of the FEP in canonical format. If the Token Ring or
noncanonical format of the MAC address of the FEP is 4000.3745.0001, the
canonical format is 0200.ECA2.0080.
----------------------------------------------------------------------------
---- Note Some environments avoid this issue by using MAC addresses consisting of only "magic numbers"-numbers that are the same in canonical and noncanonical formats. These numbers are 00, 18, 24, 3C, 42, 5A, 66, 7E, 81, 99, A5, BD, C3, DB, E7, and FF. ---------------------------------------------------------------------------- ----In Figure 2-4, the data is transferred directly to a Cisco router with a CIP, but it could be any DLSw-compliant router, and the upstream SNA end system could reside on any supported media.

Hi,
Can somebody points to some good links on:
DLSW+ without token ring.
Everything that I have found include SRB and token ring.
-- Thanks syv@911networks.com
