QUESTION: 69

The P4S company connects a pair of sites with three GigE links between two routers with fairly high processor utilization. It has a great many pairs of hosts communicating between the sites, and some use applications that may be sensitive to packet re-ordering. How to maximize the utility of the links while adding minimal load to the routers?

Use policy-based routing to force all delivery order applications onto a single link and configure per-packet load sharing across the remaining two links
Verify that the total delay of each link is within 100 milliseconds of the other two links and configure per-packet load sharing across the three links
Set the link metrics so all three paths are installed in the routing table and use the default per flow load sharing across the links
Use multilink PPP to bundle the three links into a single logical link and adjust the routing metrics as needed
