IPX/Triggered

Write security:3; Readsecurity: 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

theRIP andSAP timers setin Configuration/IPX/RIP Timer andCon-

figuration/IPX/SAP Timer.

IPX/Type 20 Packets

Write security:3; Readsecurity: 5

For certain protocol implementations, likeNetBIOS, to functionin the

NetWare environment, routes must allow a broadcast packet to be

propagated throughout the IPX networks. The Type 20 IPX packet is

used specifically forthispurpose. Thiscausesspecial handling ofthis

packet by the Express 6100/6120. 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 RouterSpecificationfrom Novell

notes that Type 20 packets should not be propagated across slower

links with bandwidths of less than 1Mbps (like ISDN). However,

whensettoPass (def),theExpress6100/6120willallowthesepackets

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.

»» PPP Profile/Bridge

The Bridge menu contains the parameters needed for exchanging

bridged packets with the PPP peer.

Bridge/Mode

Write security:3; Readsecurity: 5

When set to On (def),theExpress 6100/6120will attempt to negotiate

PPP BCP withthe PPPpeer. Bridging can beused even in routemode

only ifthe 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.
