Traffic-Limit

[Alcides Miguel]

Hello folks,

I'm looking for help on traffic limit (shapping) 'cause I've a Hub-and-Spoke topology where the remote site are all using 128K and I would like to avoid congestion making the egress and ingress traffic not going over the link capacity.

best regard,

Alcides

Hi Alcides,

this configuration does not have many difference from a non-configured policy. If your only class is going to be the default class, it is probably worth to cosider the following two options:

a) To avoid the rate-limit implementation leaving your router on a best effort behaviour

b) Implementing CAR or policing

c) Implementing CBWFQ with hierarchical shaping ( this would be my favourite)

It's my understanding that your environment is an Enterprise and not an SP, so just evaluate these options...

If you have 22 * 128 Kbps, then yes your hub physical bandwidth can exceed 1 Mbps.  Did you have a requirement to restrict the hub's physical bandwidth consumption too?

No, at hub site there's no requirement to restrict traffic
