Static Paths
Static path definitions allow a router to setup circuits without sending explorers. The path specifies the
peer to use to access a MAC address or NetBIOS name.
To configure static paths to minimize explorer traffic originating in this peer, use one of the following
commands in global configuration mode, as needed:
Static Resources Capabilities Exchange
To reduce explorer traffic destined for this peer, the peer can send other peers a list of resources for which
it has information (icanreach) or does not have information (icannotreach). This information is
exchanged as part of a capabilities exchange.To configure static resources that will be exchanged as part
of a capabilities exchange, use one of the following commands in global configuration mode, as needed:
Filter Lists in the Remote-Peer Command
The dest-mac and dmac-output-list options allow you to specify filter lists as part of the dlsw
remote-peer command to control access to remote peers. For static peers in direct, FST, or TCP
encapsulation, these filters control which explorers are sent to remote peers. For dynamic peers in TCP
encapsulation, these filters also control the activation of the dynamic peer. For example, you can specify
at a branch office that a remote peer is activated only when there is an explorer frame destined for the
Media Access Control (MAC) address of an FEP.
The dest-mac option permits the connection to be established only when there is an explorer frame
destined for the specified MAC address. The dmac-output-list option permits the connection to be
established only when the explorer frame passes the specified access list. To permit access to a single
MAC address, use the dest-mac option, because it is a configuration “shortcut” compared to the
dmac-output-list option.
