1)两个VLAN:
; /27 is 30 IPs, less one for the gw IP
vlan10: 192.168.0.0/27
vlan 20: 192.168.0.32/27
192.168.0.64/26 (192.168.0.64-128)(unused, reserved for future use in HQ or elsewhere)
2) 单网:
; /28 is 14 IPs, less one for the gw IP
192.168.0.224/28
192.168.0.240/28 (1928.168.240-256)(unused, reserved for future expansion)
3)点对点链接
HQ end: 192.168.254.253/30
Remote end: 192.168.254.254/30
4)通过总部路由互联网
HQ router redistributes 0.0.0.0 0.0.0.0 in RIP to remote
5) 防火墙
Install a firewall in bridged/transparent mode
6) RIPv2
HQ advertises 192.168.0.0/26 and 0.0.0.0/0 to Remote over PtP link
Remote advertises 192.168.0.224/28 (expand to /27 if you use the expansion block) to HQ over serial link
