Vwaas Solution and Appnav XE integration

[Ario M. Fanie]

Dear Cisco Support,

This is my first time for sizing waas, i want to ask few questions. I am designing for 500 remotes routers and 4 DC ASR routers - 3 DRC ASR routers, Wave as central manager in DC and DRC.

1. What happen when the connection of users are greater than maximum connection capability of ISR WAAS / waas express in branches area ?

in the remotes areas, using ISRWAAS SSD 4321+ / 1941+waas express

2. In the DC, i am going to use 4 server vmware installed vwaas 50 K, and appnav in all 4 ASR routers

I am assuming for the appnav-xe for this solution. Several questions :

2.1. How to implement appnav-xe with server vwaas interconnection ? The document seems separeted and not really detailed.

2.2 For the interface virtual in server VWAAS, Can this be mapped to the vmware networking ? I can not find a complete tutorial for this matter.

in DRC, i am going to use 3 server vmware installed vwaas 50 K, and appnav in all 3 ASR routers

3. The connection for the DC and DRC will be active-active, What are the best solutions for the high availability and active-active solutions.

4. What are Switch configuration to waas server configuration ? Right now using cisco 3850 IP base

I have attached the network diagrams.

Thank you

Hi Ario,  Sorry that you have not received any replies on this yet.  I am working on a similar project.  More of a full hardware replacement (Dual 2821(EOS) > Dual ISR 4331.  I have the hardware in a lab and I have been working on IWAN(DMVPN) and WAAS.  No where near the scale you have.  I doubt that I can answer many of your questions.  I can commiserate on what seems to be disconnected or unclear documentation but that is the struggles of doing oneself and not simply hiring a VAR.  ;-)

Q1) I did read somewhere that connections over the limit are simply not optimized.

Sorry on the other questions.
