dear all, just wanted to get a view on specific bit of (dynamic) VTI configuration to support connections from systems running cisco vpn client software for windows.
re the ip addressing of the 'virtual-template' from which the dynamically created (tunnel) interfaces are created
examples use 'ip unnumbered loopback0' with a related loopback configuration which has some (arbitrary) ip address configured.
QU. does this ip address and subnet actually have any significance ? i have seen 127.0.0.1 used on windows systems?
it would seem 'important' as this will be the source of all packets going from the router over the tunnel interface ?
