I have a need to use a GRE tunnel to connect two subnets across my WAN, but I've never created a tunnel before and I'm not quite sure the correct process.
In SiteA I have 184.108.40.206/30, and at SiteB I have 220.127.116.11/29.
I have a host in SiteB (18.104.22.168) that needs to route to a series of networks that are reachable via the SiteA 22.214.171.124 network.
So I know I need to create a tunnel interface at each site, and set destination and source IP's. Does it matter what I use for the tunnel interface IP? Also, the subnets at each site are on Vlan interfaces, so do I use those as the destination and source IP's for the tunnel?
Thanks in advance,
