Configuring DLSw Services
3-14 114063 Rev. A
Once a router knows that a DLSw peer can reach a specific system, the router can
address frames directly to that peer and avoid unnecessary broadcast traffic on the
TCP/IP network.
You typically define as configured peers:
• One slot in each DLSw-capable remote Bay Networks router in your TCP/IP
network to which broadcast traffic must be forwarded
• Any other RFC 1434- or RFC 1795-compliant peer in your TCP/IP network
You define each configured peer by specifying its unique IP address on the
TCP/IP network
Once you initialize DLSw services, the local router establishes two TCP
connections (one for transmitting, one for receiving) between each local
DLSw-capable slot and every configured peer in the TCP/IP network. Remote
DLSw peers on the network follow the same procedure. DLSw uses TCP ports
2065 and 2067.
Simplifying the Peer IP Table
Bay Networks provides two mechanisms for reducing the number of required
entries in the DLSw Peer IP Table. These are
• Broadcast peers
• Unconfigured peers
Broadcast Peers
It is not necessary to enter more than one peer per remote router into the Peer IP
Table. The entry representing the remote router is the broadcast peer for that
router. Only broadcast peers normally receive broadcast frames from another
router. However, all DLSw peers on a remote Bay Networks router can both
receive and respond to broadcast frames that the broadcast peer in that router
forwards internally.
