At 96% we allways have the pending routes problem into the FIB on
convergencies.
We deal with one full table on a routing instance and have fill 80% of
memory. On others PE routers 92% of memory is used.
On the providers routers (without BGP) the memory is around 26%.
How can I check the percentage used by BGP routes?
