this type of packet, it rebroadcasts it across all interfaces except the one
it is received on and includes the network number of that interface in
the data portion of the packet. The IPX Router Specification from No-
vell notes that Type 20 packets should not be propagated across slow-
er links with bandwidths of less than 1Mbps (like ISDN). However,
when set to Pass (def), the Express L128T S/T will allow these packets
to propagate over the WAN connection. This facilitates dial-on-de-
mand applications. When set to Block, all Type 20 packets are not
propagated across the WAN connection.
Connection List/Bridge
The Bridge menu contains the parameters needed for exchanging
bridged packets with the PPP peer.

Write security: 3; Read security: 5
When set to On (def), the Express L128T S/T attempts to negotiate
PPP BCP with the PPP peer. Bridging can be used even in route mode
only if the PPP peer cannot support certain PPP protocols for that par-
ticular routing protocol. See Bridge/WAN IP Bridge on page 3-24 and
Bridge/WAN IPX Bridge on page 3-25 for further details.
Connection List/Probe
The Probe feature on the Express L128T S/T is mainly used for allow-
ing a network to have multiple virtual network connections to many
destinations using the single ISDN link. The Express L128T S/T can
periodically obtain routing information from various locations and re-
tain this in the routing tables, thereby permitting the LAN connection
to be aware of the networks at this location. Probe helps keep route ta-
bles updated. When a service or network connection is required, the
Express L128T S/T can demand dial that location. This can be benefi-
cial for remote IPX workstations that cannot boot up properly without
knowing the IPX services that would be in the Express L128T S/T's
SAP table.
