Hi Networkers, One of my clients requires Internet conductivity for 2 of the sites which are interconnected using L2 link. Client is very specific about the requirements. I have attached the Diagram for more understanding of the current infrastructure. Each site has 3 internet lines, where 1st internet line at each will be receiving a default route from the ISP, and other 2 links will be configured with static routes in the Edge Routers. Requirement is as below. 1. Always both sites must use internet 1 link in Site 1. In case of link failure it should use internet 2 link in Site 2. 2. In case both Internet 1 links are failed, Site 1 should use it's Internet 2 link only, and Site 2 should use Internet 2 link in same site.  3. Same as 2 point for the 3rd Internet link.   My plan is to achieve this using iBGP and extending it up to Core Switches. Core switches are cat9k, comes with Network Advantage licenses, so it should support advance routing. Kindly provide your valuable suggestions and recommendations to provide the best design using iBGP or any other routing protocol.   ... View more

The project I am working on requires to connect one Meraki switch with 2 Cisco Catalyst 2960X switches. Meraki Switches support only RSTP/STP meanwhile Catalyst supports PVST/MST. In this case I believe best scenario is to have MST running in Catalyst so RSTP will be compatible from Meraki side.  But I am in a position where I have to change the default native vlan from 1 to something else. In this case what would be the suggested configuration from Catalyst switch side?  I am thinking to have Native VLAN mapped to MST instance 0. Is this the right practice? Your valuable feedback is highly appreciated. ... View more
