To help you control IPX type 20 packets more flexibly, this configuration allows IPX type 20broadcast packets to be propagated to only certain remote devices under certain conditions (forexample, only when the connection is up, or always).IPX ISOLATED M ODECONFIGURING IPX I SOLATED M ODEU SING CFGEDIT1.
