Quagga as border router

[Bruce M. Simpson]

Folks have been asking about XORP in this thread.

XORP can take a full BGP feed just fine as long as you have enough 
memory.; for a full default-free-zone feed, you are looking at in the 
region of 1GB - 1.5GB, perhaps less if you use aggregation.

If you look at the NSDI '05 paper you'll see that it has a number of 
benefits over existing designs, BGP route propagation in particular 
should be faster:

The architecture is deliberately structured so that forwarding 
functionality may be implemented in hardware. I believe XORP may work 
with the NetFPGA but don't have firm information about this.

IPv6 support is strong as XORP was designed to route IPv6 from the start 
as a whole suite - multicast support is also strong.

years, and still actively contribute code to the project.]
