Addresses assigned to loopback interfaces tend not to change when the router is moved between networks or to another physical location, so this is mostly for convenience. It is also usefull if you have set ACLs to protect your Netflow collector from receiving bogus data - you wouldn't need to change the ACL because the address assigned to loopback intfc remains the same. v. _______________________________________________ Flow-tools mailing list [EMAIL PROTECTED] http://mailman.splintered.net/mailman/listinfo/flow-tools
