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 attempt s 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 opti onal 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 conf igure 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 sam e protocol keywords as the x25
map command. Encapsulation PVCs also use a subset of the options
defined for the x25 map command.
