VINES Implementation Notes

303544-A Rev 00

2-7

A router connected to another loop should be the last router you configure in

that loop (Router 3 in Figure 2-3). The numbers shown in the routers in Figure

2-3

indicate the order in which you should configure the routers. Note that

with Router 4 or 5, it does not matter which one you configure first because

neither one connects to another loop.

Enable the Use of FRP Header parameter on all the WAN interfaces after

you configure all routers in the loops, and they are routing with VINES

enabled.

Fragmentation Protocol and VINES Performance

The setting of the VINES FRP header affects how VINES services perform.

Specifically, enabling or disabling the FRP header affects the maximum

forwarding rate and throughput. When the FRP header is enabled, the default,

forwarding rate and throughput slow down. When you disable the FRP header,

performance of these factors improves.

It is not necessary to enable the FRP header on all WAN links. Enabling

fragmentation is appropriate for low speed WAN links. You do not need to use the

FRP header on high speed links where the MTU setting is 1500 bytes (the default

setting).

If you experience performance bottlenecks over a WAN link (especially over a

higher speed WAN link) using VINES, disable the use of FRP header on the

VINES interface on both sides of the WAN link. For information on changing the

FRP Header parameter, refer to “Editing VINES Interface Parameters

” in Chapter

Help Thy Neighbor Support

VINES services for the router supports the Help Thy Neighbor feature. If a

neighbor advertises that a network is unreachable, and the router has an alternative

connection to that network, the router issues a “changes only” routing update.

This advertises the connection to the neighbor and in the next scheduled update.

Note:

Changing the default for FRP to Disabled in routers running Version

8.10 may cause backward compatibility problems, if the router on the other

end of a WAN link is running a lower software version with FRP enabled.
