The router also has built-in RIP (Routing Information Protocol) by default. If
the neighbor routers have the same protocol, the RIP will be used for
exchanging routing information. Here, the Static Route Setup just provides a
way to guide specified IP packets through specified routers statically. This
chapter is for you to configure static routes with your Vigor router.
9.2 Configuration
Add Static Routers to Inside Private and Public Networks
Assume the Internet access setup has been configured and the router
worked properly. You use the 1st subnet address 192.168.1.0/24 to surf the
Internet and also an internal private subnet 192.168.10.0/24 via an internal
router (192.168.1.2/24) and an internal public subnet 211.100.88.0/28 via an
internal router (192.168.1.3/24). Also, the router 192.168.1.1/24 is a default
gateway for the router 192.168.1.2/24.
1. Click LAN TCP/IP and DHCP Setup, select RIP Protocol Control
as 1st Subnet, and then click OK button.
To set RIP Protocol Control as 1st Subnet has two different purposes.
The first one is that the LAN interface could be exchanged RIP packets
with neighbor routers via 1st subnet (192.168.1.0/24). The second one is
that those inside private subnets (ex. 192.168.1.0/24) could be NATed by
the router to the Internet, but do IP routing for each other as well.
