just wondering if it is possible to have a site to site tunnel with each side using a different subnet mask? My issue is that I setup a tunnel between two sites. One site is using a 23 bit mask (10.9.6.0 /23) and the other site is using a 24 bit mask (10.10.10.0 /24). The configs mirror each other on both sides but I keep getting an error indicating that there is a mask mismatch. Once I change the configs so that each site's mask matches ex I change 10.10.10.0 /24 to 10.10.10.0 /23, the tunnel comes up.
