[c-nsp] rate-limit 2 subinterfaces with shared bandwidth

[Rens]

Maybe I didn't explain myself very well but, here is what I want to do:

 

Fa0/0 = WAN at 10 Mbps

 

Fa0/1.100 & Fa0/1.101 currently rate-limited each at 8 Mbps

 

rate-limit input 8192000 1536000 2048000 conform-action transmit
exceed-action drop

rate-limit output 8192000 1536000 2048000 conform-action transmit
exceed-action drop

 

But Fa0/1.100 & Fa0/1.101 should never go over 8 Mbps together so they won't
saturate my 10 Mbps WAN and always have 2 Mbps left
