[c-nsp] Per packet load balancing with low latency

[Tony Varriale]

William,

Note that some of those config items are optional.  The base config from 
Michael would be:

> interface Multilink1
> description Multiplexed Logical Connection to remote site
> ip address 1.1.1.1 255.255.255.0
> no ip redirects
> no ip proxy-arp
> ppp multilink
> ppp multilink fragment disable
> ppp multilink group 1

> interface Serial1/0/19:0
> description Connected to remote site (circuit 1)
> no ip address
> no ip redirects
> encapsulation ppp
> ppp multilink
> ppp multilink group 1


Be careful with URPF.  You may not need to modify your queues...probably 
don't unless you understand it.

And please, do not disable unreachables.
