Does anyone have any experience using Zscaler and Viptela?
Zscaler will support 2 x GRE tunnels sourced from the same public IP address.
I’m interested to learn if people are using a public IP address for the TLOC-ext subnet to allow the router not connected to DIA to establish a GRE tunnel.
OR
If the TLOC-ext is using RFC1918, does the router connected to DIA NAT the GRE (undesirable?) on behalf of the router connected to MPLS to form the GRE tunnel?
Thank you.
