AI2524 Router Card User’s Manual

Note:

Multiprotocol maps, especially those configured to carr

 

broadcast traffic, can result in significantly larger traffi

 

loads, requiring a larger hold queue, larger window sizes,

 

or multiple virtual circuits.

You can simplify the configuration for the Open Shortest Path First (OSPF) protocol by adding the optional broadcast keyword.

Configure PAD Access

By default, PAD connection attempts are processed for session cre ation or protocol translation from all hosts. In interface configuration mode, restrict PAD connections to only statically mapped X.25 hosts:

1.Restrict PAD access.

x25 pad-access

2.Configure a host for PAD access.

x25 map pad x121-address [option]

You can configure outgoing PAD access using the optional features of the x25 map pad command without restricting incoming PAD con- nections to the configured hosts.

Establish an Encapsulation PVC

Permanent Virtual Circuits (PVCs) are the X.25 equivalent of leased lines; they are never disconnected. You do not need to configure an ad- dress map before defining a PVC; an encapsulation PVC implicitly de- fines a map.

In interface configuration mode, establish a PVC:

x25 pvc circuit protocol address [protocol2 address2 [...[protocol9 address9 ]]] x121- address [option]

The x25 pvc command uses the same protocol keywords as the x25 map command. Encapsulation PVCs also use a subset of the options defined for the x25 map command.
