Hi,My SP has an ingress policer specifying 100mbps CIR and 256kbps Bc.When I try to configure a shaper to match this requirement, I cannot specify a Bc value smaller than 400000, as the Tc cannot be less than 4ms. For example,------------------------...

Hi,I need to import routes from one VRF into another. Where do I apply the import-map in ASR1k? I cannot apply it under vrf definition: the import-map command is not supported. Thanks.Larry

Hi Antonio,This is not possible. Think of one PC, say, 172.16.0.1. When it browses one website, it has a dynamic source port; when it opens another TCP/IP session to outside world, another dynamic source port is used, and so on. These concurrent ses...
