My company has a Switch 3550 as follow specification below
Cisco WS-C3550-48 (PowerPC) processor (revision E0) with 65526K/8192K bytes of memory.
Processor board ID CHK0629V0F1
Last reset from warm-reset
Running Layer2/3 Switching Image
Cisco IOS Software, C3550 Software (C3550-IPSERVICESK9-M), Version 12.2(25)SEB4, RELEASE SOFTWARE (fc1)
I Should like a tip about that switch going be support that implementation. for exemplo it has 64MB as showed above.
I'm afraid it come to crush.
some tip about what devices are advisable to deploy BGP exchange routes with Internet is welcome
That Switch it will be dedicated for BGP.
thanks.

Most layer 3 switches,do not have TCAMs large enough to allow the routing engine to hold Internet-scale routing tables. It can easily do LAN routing, but you're probably not going to get away with running BGP on it.

Hi,
Yes. As you mentioned 64 MB is definitely not sufficient to hold the entire internet routing table. It would definitely create huge issues. The minimum memory requirement to support the full internet routing table is 512 MB dedicated for the BGP process alone. You can keep this in mind while selecting a device. My choice would be a Cisco ASR1K device.
