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 L128FP. When a router receives this type of
packet, it rebroadcasts it across all interfaces except the one it is re-
ceived 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 L128FP will allow these packets to
propagate over the WAN connection. This facilitates dial-on-demand
applications. When set to Block, all Type 20 packets are not propagat-
ed 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 L128FP 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 par-
ticular routing protocol. See Bridge/WAN IP Bridge on page 3-22 and
Bridge/WAN IPX Bridge on page 3-23 for further details.
