Defining a DLSw+ Remote Peer

Defining a remote peer in DLSw+ is optional, however, usually at least one side of a peer connection has

adlsw remote-peerstatement. If you omit the dlsw remote-peercommand from a DLSw+ peer configuration, then you must configure the promiscuous keyword on the dlsw local-peer statement. Promiscuous routers will accept any peer connection requests from other routers that are not preconfigured. To define a remote peer, use the dlsw remote-peercommand in global configuration mode.

One of the options in the remote peer statement is to specify an encapsulation type. Configure one of the following types of encapsulations with the dlsw remote-peerstatement:

•TCP Encapsulation, page 289

•TCP/IP with RIF Passthrough Encapsulation, page 290

•FST Encapsulation, page 290

•Direct Encapsulation, page 291

•DLSw Lite Encapsulation, page 291

Which encapsulation type you choose depends on several factors, including whether you want to terminate the LLC flows. TCP and DLSw+ Lite terminate the LLC, but the other encapsulation types do not. For details on each encapsulation type, see the DLSw+ Design and Implementation Guide. See the “Local Acknowledgement” section in the overview chapter of this publication for a discussion on local acknowledgement.

TCP Encapsulation

To configure TCP encapsulation on a remote peer, use the following command in global configuration mode:

Command	Purpose
Router(config)# dlsw remote-peer list-numbertcp	Defines a remote peer with TCP encapsulation.
ip-address [
[ip-addressframe-relay interface serial
number dlci-number interface name]]
[bytes-netbios-out bytes-list-name]
[circuit-weight weight] [cluster cluster-id]
[cost cost] [dest-macmac-address]
[dmac-output-listaccess-list-number]
[host-netbios-out host-list-name] [inactivity]

minutes] [lsap-output-list list] [no-llc
minutes] [passive] [priority] [rif-passthru
virtual-ring-number] [tcp-queue-maxsize]
[timeout seconds]

The following command specifies a dlsw remote peer with TCP encapsulation:
