[c-nsp] load balancing

[Brian Feeny]

It can be done with pbr.

Setup a loopback on the remote ISP router, say (ex: 1.1.1.1)

then make 2 static route that get you there:

ip route 1.1.1.1 255.255.255.255 3.3.3.2 (3.3.3.2=next hop of t1 #1)
ip route 1.1.1.1 255.255.255.255 3.3.3.6 (3.3.3.6=next hop of t1 #2)

then in your pbr, set the next hop to be 1.1.1.1

make sure cef is enabled, and under each t1 interface make sure ip cef  
load-sharing per-packet
is enabled.

Their are other ways this could be done too.
