Traffic of Periodic RIP and Periodic SAP Packets on Group-Defined Interface
When IPX is defined on an interface where multiple VCs or multiple DLCIs are
grouped, periodic RIP and periodic SAP packets are broadcast to all the VCs or DL
in the group. Consequently, it is cautioned that an inadvertent addition of IPX
definition to an existing grouped interface may cause unnecessary traffic to flow
through the interface if the group includes a VC or DLCI not using protocols othe
than IP. To avoid such occurrence of unnecessary traffic, it is advised to separate
group into two—one comprising VCs or DLCIs to use IPX, and the other not usin
