DLSw Configuration Overview
114063 Rev. A 3-11
The router uses this IP address to establish the TCP sessions between peers in a
DLSw network. Generally, the IP address that you select is either the circuitless IP
address or the IP address of any interface on this slot. However, it is acceptable to
use the IP address of any interface on any slot.
If a unique IP address is not available, you must perform one of the following
tasks:
• For configurations that do not have as many physical IP interfaces as DLSw
slots, add IP addresses to one or more IP-capable interfaces. If required, a
single interface can support multiple IP addresses. For example, you might
want to do this in large SDLC configurations, because IP cannot be configured
on SDLC interfaces. For more information on configuring multiple IP
addresses, see Configuring IP Services.
• For single-switch operation, enter any valid IP address that is available but not
used in your network. This address should be on a unique IP subnet.
Figure 3-6 shows a sample network with three routers running DLSw. Although
many options exist for the Slot Table, this network uses the following values in the
Slot Table:
• Router A, the central site router, has three slots running DLSw, as follows:
-- For Slot 1, the circuitless IP address is used in the Slot Table to represent
this slot. This provides the highest availability for Token Ring devices.
-- For Slot 3, the IP address of the directly attached Frame Relay interface
represents this slot in the Slot Table.
Note: You can use the circuitless IP interface address for one (and only one)
DLSw-capable slot. Using the circuitless IP interface allows TCP connections
for DLSw services on that slot to be less dependent on the availability of
specific physical circuits or data links. Bay Networks recommends that you set
the Keepalive Time parameter to a nonzero value when using the circuitless IP
address. (For more information on the circuitless IP interface, refer to
Configuring IP Services.)
