All 3 sessions will stay up (2x link + bundle session) I'd recommend experimenting with the following parameters: ppp multilink fragment size <xxx> (try values from 500 to 800 bytes, could be tx or rx reassembly bug) ppp multilink fragment disable (perhaps it's frag processing that rolls counters over a cliff -- just force per member round robin'ing with this) also for grins, I've seen cases where mlppp frags on multi-member links wedge the receiver of the frames when the DF bit is 1. try wiping it on your IP transit facing ports, and at the user facing CPE ethernet port with something like: route-map clear-df permit 10 set ip df 0 Lastly, do you enable or use mlppp interleaving, per chance? -Tk _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
