What's best approach for frame-relay traffic shape in following
configuration?
Hub (1024K line, 512K CIR)
|
------------------------------------------
| | | | |
Site A B C D E
All remote sites are 256K line speed with 128K CIR.
Here is my dilemma,
If I configure following parameters at all sites, the hub site will
start shaping when it reaches 128K. If I configure hub site with 512K of
CIR, it can saturate remote site since remotes are small CIR.
map-class frame-relay frame-shape
frame-relay cir 128000
frame-relay mincir 64000
frame-relay adaptive-shaping becn
frame-relay bc 8000
frame-relay be 16000
Here is the approach I am thinking of:
1. Configure hub with sub interfaces.
2. Have sub interface parameters match remote site paramters.
Does it make sense? Any better option?
Thanks,
Sam
