Full BGP on 4500

Hello,

Can the Cat 4500 support multiple BGP peers that are sending full tables? How much RAM is needed? Has anyone seen this in production?

Thanks,

Lee

The Cat4500 can't take a full table regardless of RAM. They have a max of 131,072 entries in the routing table, unicast and multicast combined. See the "Predictable Performance" section of the data sheet:

look at this link:http://www.cisco.com/en/US/products/hw/switches/ps4324/products_data_sheet0900aecd803fae7d.html#table1

and i think amount of RAM is depends on your network design and configuration of aggregation as well as summerisation...

Hi Lee,

Which sup engine you are running. It has to be Sup4/5/5-10GE. These are the only sup engines which support full layer 3 routing protocol funcationality. These all comes with default 512MB and it should be suffiient to get the full routing table on them. Depends on how many BGP sessions you have that are feeding the router a full table but 128MB is the effective minimum.

HTH,Please rate if it does.

Thanks Amit!

Is the Sup4/5/5-10GE blade upgradeable to 1gb ram? Are the other sup blades for the 4500 upgradeable also?

thanks,

Lee
