Hi,
The bandwidth assigned to the main interface will be
used on the subinterfaces, unless theres a bandwidth
command on the subinterface which will override the
bandwidth defined on the main.
Example:
int s0/0
band 1000
int s0/0.1 point
ip address ...
int s0/0.2 point
ip address ...
bandwith 256
int s0/0.3 point
int s0/0, s0/0.1, s0/0.3 will have a bw of 1000
int s0/0.2 will have bw of 256
If you have different CIRs for each PVC and want EIGRP
to use CIR as part of the calculation then define the
bw on each sub. Keep in mind that you probably will be
going above the guaranteed CIR most of the time unless
there is congestion. I don't know of a way to adjust
the bw for when traffic-shaping throttles back to the
mincir.
I'm not aware of any preferences or rules. Since
bandwidth is used, it could have a negative/positive
impact on your network routing depending on your
network, etc.
