Configuring DLSw Services

3-10

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-compliant peer in your TCP/IP network.

You deﬁne each conﬁgured peer by 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

Any DLSw slot that receives a broadcast will forward that frame to all other

DLSw slots in this same router. Therefore, 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.

Unconﬁgured Peers

A Bay Networks router running DLSw can respond to requests from remote

routers to initiate DLSw sessions, even if the remote peer is not deﬁned in the

local router’s Peer IP Table. Once a DLSw session is established to a remote slot,

that slot is dynamically added to the list of known peers. Any remote DLSw peer

that the router learns dynamically is an unconﬁgured peer. These peers are not

listed in a router’s Peer IP Table.

Unconﬁgured peers are supported only if the DLSw Reject Unconﬁgured Peers

parameter is set to Accept.
