Hi everyone,
I hope you all are doing fine.
Below is my requirement:
1) Can support BGP, RSTP/STP, OSPF.
2) we will announce only one summary route to Provider
3) We will receive only default route from Provider
4) We have dual ISP for fail over.
5) Each Provider provides 200M DIA CKT
We have a couple of C3840-24T left over, I am thinking to use them rather than buying new routers.
In our network we use them as ACCESS SWITCHES, but I am thinking why we can not use that for CE as it does meet all our requirement. I just want to get you guys feedback.
Data center to Branch office:
We have 200 M CKT between Data center and our branch office, same requirements:
1) OSPF
2) HQOS
So again I am thinking to use 3850-24T, I understand they are usually used for ACCESS layer, but why I can not use it as it does meet the requirement. Appreciate any feedback!!
Thanks and have a weekend!!

Hi
Alright, thank you, it it is WS-C3850-24T-S, it could be upgraded to IP service license in order to be able to use BGP.

Hello,
as far as I recall. the 3850 does not support NAT, so if you want to use at as an ISP facing device, that is probably going to be a problem...

Thanks, no , we down stream FW will do NAT, 3850 will only be used to get default route from Provider via BGP and announce our IP SPACE via BGP.

Hi
Im not sure the reason to use this switch but take in consideration as Georg mentioned, the NAT is not supported on switches (it can be supported on 6500, 6800 and I think on 9K), now if you want to enable routing you must have a proper license, like showed below:
Cisco IOS Software Feature Set Differences
My suggestion is verify if that switchport IP Base or IP Services license. Some switche have IP LAN and IP Services license by default.

Hope it is useful
