9. Item #8, above, can be verified by checking that:
RtGwy & Prt4Mask) == (Prt4IP & Prt4Mask) || (RtGwy & Prt5Mask) == (Prt5IP & Prt5Mask)
TARGETS
WRONG ROUTE CONFIG
Description: A route with mismatched destination and mask has been configured.
Message: “Wrong route configuration.
”What to do: Rectify the IP address and mask of the mis-configured route.
TOPOLOGY EXAMPLE
Figure 4-12: Topology Example
In the above figure: Topology Example, the 8 Series device is connected through the two
Ethernet ports available on the communications card.
• Port 4 (IP address 10.1.1.2) connects to LAN 10.1.1.0/24 and to the Internet through
Router1. Router 1 has an interface on 10.1.1.0/24 and the IP address of this interface is
10.1.1.1.
• Port 5 (IP address 10.1.2.2) connects to LAN 10.1.2.0/24 and to EnerVista setup
program through Router 2. Router 2 has an interface on 10.1.2.0/24 and the IP
address of this interface is 10.1.2.1.
Configuration
Network addresses:
PRT54IP ADDRESS = 10.1.1.2PRT4 SUBNET IP MASK = 255.255.255.0PRT5 IP ADDRESS =
10.1.2.2PRT5 SUBNET IP MASK = 255.255.255.0
Routing Settings:
IPV4 DEFAULT ROUTE: GATEWAY ADDRESS = 10.1.1.1
STATIC NETWORK ROUTE 1:
– RT1 DESTINATION = 10.1.3.0/24RT1 NET MASK = 255.255.255.0RT1 GATEWAY =
10.1.2.1
Behavior: One static network route was added to the destination 10.1.3.0/24, where a
laptop running EnerVista is located. This static route uses a different gateway (10.1.2.1)
than the default route. This gateway is the address of Router 2, which is “aware” of
destination 10.1.3.0 and is able to route packets coming from the 8 Series device and
destined to EnerVista.
