AW: [f-nsp] BGP: No path is selected as BEST route

[Gunther Stammwitz]

Hello colleagues,

The system-default values are something one doesn't think about when there
are problems.

I'm currently fighting with a problem where vlans and
spanning-tree-instances are limited.
On a B8GMR I can only set no more than 128 spt-instanced and only up to 512
vlans...
vlan                 16         512        512       
spanning-tree        32         128        128   
... But on my J-B2GMR4 I can use many more vlan-instances:
vlan                 32         4095       512       
spanning-tree        32         128        32  

Both routers are using the image B2R07801c.bin and I guess that these values
are somehow limited by the available system an cam-memory.
Is there some sort of guide how many instances one can set depending on the
type of management module and installed memory?


Another thing I've once read somewhere in the documentation is that one can
install a switch-only image on the Bigiron routers. Would this image help in
increasing the spt-instances and vlans? Another idea might be to reduce the
size of ip-routes and ip-cache so that one can increase the other values.
Does anyone of you have a hint for me or maybe the url of the appropriate
document?

Thanks in advance,
Gunther
