Description (partial)

Symptom:
Stage2lbgroup consumption details given below, which appreas to be unreasonable and causing OOR


1) Steady state with 190 interfaces in system out consumption is at 2400. This is with no routes, no protocol neighbors in the system.
2) Every time we add/delete bundle vlans, consumption is different. With 100 vlobs, we were seeing 960 entries consumes. Removing and reading these vlans takes the consumption down to 500, still high
3) With 500 vlans, consumtion was at 1500. Removing reading these vlans takes back the consumption to 1000
4) All above observations are with no protocol peering and routes advertised to the box.
5) System with just 1600 overall vlans consumes close to 6k entries (subjected to change every time we remove re add). Protocols and routes consumption is minimal, but we run into OOR easily due to the above fake consumption
6) NPI consumption is at 2400 and HW is programmed only 937, why so much difference ?

Conditions:
add/remove config
