Hitachi GR2000 manual Interface Address in Point-to-Point Line Connection

When you connect GR2000 with devices other than GR2000 based on the IP routing, pay attention to the following.

4.7.1Interface Address in Point-to-Point Line Connection

GR2000 regards the route information in the point-to-point line connection (direct connection) as two host routes. This method is also adopted in Hitachi routers NP220, NP200, and NP150. Accordingly, when a network only consists of these routing devices, you can assign interface addresses to the point-to-point line as follows. Be careful not to use this method with any other routing device.

You can assign the same network IP address or subnetwork IP address to

￿multiple point-to-point lines.

You can assign two different network IP addresses or subnetwork IP addresses to both ends of a point-to-point line.

Note: Although GR2000 treats the route information of a point-to-point line as two host

*routes, Cisco Systems’ routers treat such information as one network route. This causes a discrepancy in the route information advertised by the routing protocol.
