We have a working site to site vpn (multiple really) lets say 192.25.15.x/24 to 192.25.16.x/24. Works perfectly. We need to add a set of vlans to a different interface on the sonic at the .16 site. These vlans are created on a cisco switch with addresses of 192.26.16.x/25, /27, and 2 /28. These devices have vlan routing done in the cisco, and they can reach the internet, and the devices on the 192.25.16.x subnet. However, I cannot get the connection from the new vlans to the other site across the vpn.
The cisco switch is connected to the x3 interface and there is a route between them 10.0.0.x/24 on each end.
I have created the routes on the switch and the sonic to get to the new subnets.
I have placed the new subnets into a network group with the other .16 subnet and made sure that new group is defined in the VPN policy and double checked...
