IPX/Triggered
Write security: 3; Read security: 5
When set to Yes, only IPX RIP and SAP updates are sent when the
routing or service table has changed and learned routes are not
"aged." When set to No (def), updates are sent periodically based on
the RIP and SAP timers set in Configuration/IPX/RIP Timer and Con-
figuration/IPX/SAP Timer.
IPX/Type 20 Packets
Write security: 3; Read security: 5
For certain protocol implementations, like NetBIOS, to function in the
NetWare environment, routes must allow a broadcast packet to be
propagated throughout the IPX networks. The Type 20 IPX packet is
used specifically for this purpose. This causes special handling of this
packet by the Express L768. When a router receives this type of pack-
et, 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 Novell notes that
Type 20 packets should not be propagated across slower links with
bandwidths of less than 1Mbps (like ISDN). However, when set to
Pass (def), the Express L768 will allow these packets to propagate
over the WAN connection. This facilitates dial-on-demand applica-
tions. When set to Block, all Type 20 packets are not propagated
across the WAN connection.
»» PPP Profile/Bridge
The Bridge menu contains the parameters needed for exchanging
bridged packets with the PPP peer.
Bridge/Mode
Write security: 3; Read security: 5
When set to On (def), the Express L768 will attempt 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 particu-
lar routing protocol. See Bridge/WAN IP Bridge on page 3-22 and
Bridge/WAN IPX Bridge on page 3-23 for further details.
