Hello again. On page 419 of Doyle's book, it explains that "if the DR fails, a new DR must be elected,new adjacencies must be established, and all Routers on the network must synchronize....while all this is happening, The network is UNAVAILABLE for transit packets." My question is: What about EXISTING sessions between DROTHERs, will these get Interrupted when the DR fails? Or is this in reference to packets using the Area where the failed DR is as a TRANSIT area? Wouldn't individual routers still maintain a CACHED copy of which way To route remaining packets (e.g. to complete an FTP download?) Elmer Deloso
