DC1 BIG-IP routing analysis
This discussion examines the routing table for the BIG-IP devices in
data center 1 (DC1). The discussion references diagrams and tables that you can link to
below.
- For references to DC1, refer to Data center 1 routing diagram and table.
- For references to DC2, refer to Data center 2 routing diagram and table.
A quick look at either of the routing tables reveals
that a number of the routes needed for the system illustrated in the corresponding routing
diagram are not included in the table. That's because devices that are on the same subnet
do not need a static route.
- eth0 to DC1 BIG-IP devices on the Discovery subnet
- The entry for this route is in cell A23. The static route goes from the eth0 NIC in DC1 to the discovery subnet in DC1. It is specified in the table as:10.1.1.0 255.255.255.0 10.4.4.254
- The first octetspecifies the destination IP address used to communicate with the Discovery subnet in DC1.10.1.1.0
- The next octet255.255.255.0specifies the network mask for this subnet.
- The last octet,10.0.0.254is the gateway for this subnet.
- eth0 to DC2 BIG-IP devices on the Discovery subnet
- The entry for this route is in cell A24. The static route goes from the eth0 NIC in DC1 to the discovery subnet in DC2. It is specified in the table as:10.101.101.0 255.255.255.0 10.4.4.254
- The first octetspecifies the destination IP address used to communicate with the Discovery subnet in DC2.10.101.101.0
- The next octet255.255.255.0specifies the network mask for this subnet.
- The last octet,10.4.4.254is the gateway for this subnet.
- eth3 interface to DC2 DCDs on the Listener subnet
- The entry for this route is in cell A26. The static route for the eth3 NIC is.10.103.103.0 255.255.255.0 10.5.5.254
- The first octet10.103.103.0specifies the destination IP address used to communicate with the cluster subnet in DC2.
- The next octet255.255.255.0specifies the network mask for this subnet.
- The last octet,10.3.3.254is the gateway for this subnet.
- eth3 interface to DC1 DCDs on the Listener subnet
- The entry for this route is in cell A27. The static route for the eth3 NIC is.10.3.3.0 255.255.255.0 10.5.5.254
- The first octetspecifies the destination IP address used to communicate with the cluster subnet in DC1.10.3.3.0
- The next octet255.255.255.0specifies the network mask for this subnet.
- The last octet,10.5.5.254is the gateway for this subnet.
