Jabber and Public CA-signed Certificates (Part 3 of 3)

Posted by Dishko Hristov on Nov 16, 2017 12:19:30 PM

In this third article, we will expand upon what we learned in part 1 and part 2 regarding Jabber and how to renew your CA-signed certificates. In this final article, we will examen the certification process within Cisco Expressway.

It is important to note that for Jabber Mobile and Remote Access (MRA) feature as well as for Business to Business calls (B2B), it is mandatory to have a CA-signed certificate on the Expressway-Edge node. On the other hand, there is no such requirement for Expressway-Core. However, Stack8 recommends a CA-signed certificate to be used on both Expressway servers.

Another requirement is to cross upload all Root and Intermediate certificates on both nodes in order for the Secure Traversal Zone to be active and communication between two Expressway nodes to work.

Do not forget to verify, every time you renew your certificates, if there is a change on the Root or any of the Intermediate certificates and Upload all new chain certs in the Trusted Certificates section of the server.

Cisco Router and Google Cloud VPN

Posted by John Marrett on Nov 8, 2017 9:29:02 AM

In a recent consulting engagement, our Professional Services team needed to help build a VPN connection between a series of Cisco Routers and a Google Cloud environment. We were surprised to discover that at the time we completed the project, Google did not provide a configuration guide for this common configuration type and wanted to share our experience building the connection. They have since added documentation for IKEv2 based ASR configurations. Our post highlights some important architectural details as well as the configuration requirements (tunnel mode, phase 2 timers) for the tunnels. It also makes use of an inner VRF, unlike Google's example.
