When a link goes down, you don't really notice as ppp will only sequence data when a link starves - therefore when a link goes down, only a single fragment goes missing from the data stream. This translates to a single packet (unless you have a link weight greater than the bundle MMRU) which TCP et al are fairly good at dealing with. This works with compression turned on too - at both the MP layer and the link layer. You can also have your auto links coming up and down on demand based on your needs - check the autoload options in the man page, not to mention adding and removing links on-the-fly...... > -- > ------------------------------------------------------------------------- > - Tom Arnold - the sunrise in the east every morning in my dreams, i - > - SysAdmin - turn the music on and start to dance with all my friends- > - TBI, Ltd - the sun shines on my way every night and every day and - > -------------- takes the sorrows far away, so far away. -- X-Perience - -- Brian , , Don't _EVER_ lose your sense of humour....
