Full BGP Table on Switch

[lxcollin1]

Hello,

Can any of the Cisco 1U switches support a full BGP table? If not, can they have RAM added to support a full table? What is the lowest model L3 switch that can support a full table?

I appreciate your assistance!!

Hello Lehi,

the full BGP table requires approximately 128MB of DRAM, although that depends on factors such as the number of BGP peers, filters, attributes etc.

The 1U switches such as the the 3560 are not really suited for your purpose. You need a chassis-based L3 switch such as the 4500 or 6500 in order to support the full BGP routing table.

HTH,

If youre talking about full internet BGP routing table which is around 200000 prefixes, you need 256MB of DRAM.
