Question. My company wishes to extend a vlan from our main office to 2 other geographically diverse sites over our ISP's ELAN network (sites being our NY office, our Evanston main office, and our DR which is also in Illinois). The goal is to use this for VMWare replication/ migration.
I know of two ways this can be done; either using trunks between the sites or setting up VPLS.
I am not very familiar with VPLS so I figure it is easier just to make layer 2 trunks between the sites, then creating the desired Evanston vlan in the NY and DR core switches with the vlan SVI located on the EV core switch. But for redundancy I would want to use VRRP to create a virtual IP for the vlan SVI with the EV SVI interface (IP 10.1.2.2 /24) being primary with priority 200 and the DR SVI interface (IP 10.1.2.3 /24) being the backup. Both SVI interfaces using the secondary IP 10.1.2.1 /24 IP.
Diagram illustrating topography below. Actual IP's and VLAN not shown.
