Running BGP on Cisco 9300 Catalyst Switch

[CharlesGaskin8417]

I have two remote Colo Data Centers that I plan to have a 400 Mbps DIA and 1Gbps WAVE (DWDM) circuit at, which will all connect back to the main Corp DC. I am trying to keep the cost down, so I tried to avoid getting an ISR (4331) router so that I don't have to pay for the additional fees mentioned below. I believe the 9300 switches will provide the throughput capability, with the fiber handoffs needed, along with the port density required. I do not foresee exchanging too many routes between the DC's. There would potentially be 5 - 20 prefixes needing to be advertised along with a default route from the ISP, and 4 BGP peers. 

Does anyone know any performance issues that should be concerned when using a 9300 switch for this type of deployment?

 ISR Router Fees

• 8 port NIM Card
• Boost performance lic
• Cisco One Adv Lic

I do not see any issue, make sure you have right License for Cat 9300. ( also note This is switch, do not have any capabilites of Filtering, NAT, IPSEC so on)

if these feature not required then you can connect your LES circuit.

Thanks, Balaji. I will have a Cisco FTD at each site as well to take care of the NAT, IPSEC, and Filtering.

Sure most of the WAN edge will be terminated at Layer 2 Switch Like this. if you want security you can enable MACSec (depends on requirement)

if you have FW directly connected that is protected your network, technically i do not see any issue here..
