Quagga only maintains the routing info. The forwarding is normally
being done by the kernel of the unix box you run it on.

So the forwarding speed depends on the box and kernel, not
on quagga.

Where quagga comes to play is the time it takes quagga to process
changes to routing updates.

OK

i actually use GRE to establishs BGP connections , that means all
forwarding data will going in the GRE tunnel , what do you think of
this GRE perfermence limitation ?

Depends on the kernel and cpu GHz rate used to process GRE.
What CPU is in use ? What kernel ? I assume that forwarding is
the limitation at 20 Gbit/s, not the GRE processing of the
BGP protocol.

The best way to find out is benchmarking with/without GRE,
if you have the additional spare boxes laying around 8-}

well , my quagga bgp stack , ospf stack will exit automatically in a
low rate . do you know what is going on ?

Come on, look around your bug report! That is not a valid bug report,
that is a joke! At least provide details about your setup!

Sure. It doesn't do it at all.

BGP distributes routes, not traffic. Quagga does BGP and will happily
send and receive route info.

What the underlying OS does with those routes afterwards for forwarding
traffic is not quagga's problem, it's usually a kernel problem.
