In chasis admin vdc we do only resource management. So we want to change these default template values in admin vdc. In Distribution VDC we are running BGP and OSPF. We are not taking full routing table. In Access VDC we have one vrf for management and some routes for private blocks. We have 4GB memory. Is it appropriate to distribute the resources as below?
Can you advice us?
Admin VDC
limit-resource u4route-mem minimum 32 maximum 32
limit-resource u6route-mem minimum 16 maximum 16
limit-resource m4route-mem minimum 48 maximum 48
limit-resource m6route-mem minimum 8 maximum 8
to
limit-resource u4route-mem minimum 8 maximum 8
limit-resource u6route-mem minimum 8 maximum 8
limit-resource m4route-mem minimum 8 maximum 8
limit-resource m6route-mem minimum 4 maximum 4
Distibution VDC
limit-resource u4route-mem minimum 64 maximum 64
limit-resource u6route-mem minimum 32 maximum 32
limit-resource m4route-mem minimum 32 maximum 32
limit-resource m6route-mem minimum 32 maximum 32
Access VDC
limit-resource u4route-mem minimum 4 maximum 4
limit-resource u6route-mem minimum 4 maximum 4
limit-resource m4route-mem minimum 4 maximum 4
limit-resource m6route-mem minimum 4 maximum 4

It depends on your environment. There isn't a hard rule on how to allocate the resources.

if i make default vdc ( which is not used for any purpose.9 to mimum, does it effect other vdcs?

No, it should not.
The default configuration will share resources across all VDCs. When a VDC needs more resource than the other, it will just go get it until it runs out. If you set the resource limit, it will limit resource on the VDC level.

There is ususally no need to change. Note these refer to RIB resources, which is in shared memory. The total available shared memory for the RIB for all VDCs on a physical device with 4 GB of memory is 256 MB. In 5.0.2, non-default VDC has min and max 8M by default, while in previous versions the default max was much higher. This leads me to believe system will dynamically allocate as needed.
Another important aspect not to be confused with is FIB resources, which is on the line card. When multiple VDCs are created to use the same module, the same physical FIB resources have to be shared. This has consequences when you choose modules, and plan their use per VDC. To avoid hitting FIB limits, learn this lesson at initial deployment
