[Click] RadixLookup limitations? And ARPQ with VLAN tag insertion

[Eddie Kohler]

Hi Alexander,

A Click configuration with 4096 output paths would probably overwhelm  
the machine; for instance, the configuration file itself might be too  
large to "kalloc".  I wouldn't suggest you use RadixIPLookup as is.   
Instead, write a version that maybe *annotated* the packet with an  
output branch.  Then your other elements can examine that annotation.

The 1-byte Paint annotation used in our IP router configs to check  
for redirections imposes a max of 256 output paths.

As for VLAN, can you say more?
