Running BGP on Cisco 9k switches

[carl_townshend]

Hi Guys

A quick question, we have some Cat 9K switches with Network advantage licences.

Are there any limitations when it comes to running BGP on them?

We want to just receive a default route and do some basic route maps tuning on them.

We are currently using ISR 4K routers, any disadvatanges moving to the 9K switch?

cheers

License support BGP

This SW support NAT 

And you mention that You will receive only defualt not full bgp'

So from my opinion it ok still this SW is classify by cisco as access SW not Core SW.

So handle NATing with routing and inter-vlan can add some load to cpu.

I recommend using other high end platforms like 9500 or 9600.

Thanks

Hi

We will only receive BGP default route and we will not be doing any NAT on this device.

if you have no other choose try it and monitor memory and CPU.

If you are only getting the default route from the provider you are good. with 9300-24UX or 9300-24UXM (with the latest code 17.6.X or higher)

Get a 9300X (bigger CPU and bigger memory) and plug an SSID at the back.  Do not stack the switch.

The most important thing to do is to find a software stable enough to run BGP and keep the platform from crashing every 6 months due to a plethora of memory leaks.
