The maximum number of IP interfaces for VSP 4900 Series is based on the following formulas:
If you disable the VRF scaling boot configuration flag:
= 500 – (# of VRRP IPv4 interfaces) - (# of VRRP IPv6 interfaces) – (# of RSMLT interfaces) – 2 (if IP Shortcuts is enabled) – 3x(# of VRFs)
If you enable the VRF scaling boot configuration flag:
= 500 – (# of VRRP IPv4 interfaces) – (# of VRRP IPv6 interfaces) - (# of RSMLT interfaces) – 2 (if IP Shortcuts is enabled) – 3
