There were static routes to the subnets on my router like this: ip route a.b.c.d 255.255.255.248 Se4/2:0 in this case "sh ip cef Se4/2:0" shows Prefix Next Hop Interface a.b.c.d/29 attached Serial4/2:0 and exported ip nexthop is 0.0.0.0 for that network. I've changed static routes like this: ip route a.b.c.d 255.255.255.248 gw.add.re.ss After that "sh ip cef Se4/2:0" became as follows: Prefix Next Hop Interface a.b.c.d/29 gw.add.re.ss Serial4/2:0 and exported ip nexthop is gw.add.re.ss. Now traffic is accumulated in the rdd for both in and out. I'm quite happy now... -- Alexander -- Help mailto:majordomo@net.doit.wisc.edu and say "help" in message body Unsubscribe mailto:majordomo@net.doit.wisc.edu and say "unsubscribe flowscan" in message body Archive http://net.doit.wisc.edu/~plonka/list/flowscan/archive/
