Wich router to choose for Office365 use

Safwane Madjeri

Hello everyone, I would like to ask you the following case: I'm currently working on the network part of an Office365 project. We have two types of access on sites : MPLS for corporate flows and Libo for web surfing via Zscaler (PBR on the operators routers to redirect web flows to Libo). In russia Local Internet Breakout can't be mounted directly on Operator routers. We set up cisco 881-K9 on which are mounted the GRE tunnels to Zscaler.
With the implementation of Office365 (Teams, sharepoint, Office365+...) we will increase the bandwidth of some sites (+100 users - 300 users) to 100 Mbps minimum to be able to enjoy Office365.
My question is to know if the Cisco 881 are robust enough to support the load induced by Office365 and the large number of TCP/UDP sessions.
I found on the web an ISR G2 table recommended Sizing Based on WAN Link Speed which recommends 3925 for a 100 Mbps WAN link. What is your opinion please?

Thanks in advance !
