DC1 BIG-IQ CM routing analysis
This discussion examines the routing table for the BIG-IQ CM 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.
- eth1 to DC2 BIG-IQ CM & DCDs on the Discovery subnet
- The entry for this route is in cell A5. The static route goes from the eth1 NIC in data center 1 to the discovery subnet in data center 2. It is specified in the table as:.10.101.101.0 255.255.255.0 10.1.1.254
- The first octetspecifies the destination IP address used to communicate with the Discovery subnet in data center 1.10.101.101.0
- The next octet255.255.255.0specifies the network mask for this subnet.
- The last octet,10.1.1.254is the gateway for this subnet.
- eth1 interface to BIG-IP devices on the Discovery subnet
- The entry for this route is in cell A6. The static route for the eth2 NIC is.10.104.104.0 255.255.255.0 10.1.1.254
- The first octetspecifies the destination IP address used to communicate with the Cluster subnet in data center 2.10.104.104.0
- The next octet255.255.255.0specifies the network mask for this subnet.
- The last octet,10.1.1.254is the gateway for this subnet.
- eth1 interface to DC1 BIG-IP devices on the Discovery subnet
- The entry for this route is in cell A7. The static route for the eth2 NIC is.10.4.4.0 255.255.255.0 10.1.1.254
- The first octetspecifies the destination IP address used to communicate with the Cluster subnet in data center 2.10.4.4.0
- The next octet255.255.255.0specifies the network mask for this subnet.
- The last octet,10.1.1.254is the gateway for this subnet.
- eth2 interface to DC2 DCDs on the Cluster subnet
- The entry for this route is in cell A8. The static route for the eth2 NIC is.10.102.102.0 255.255.255.0 10.2.2.254
- The first octetspecifies the destination IP address used to communicate with the cluster subnet in DC2.10.102.102.0
- The next octet255.255.255.0specifies the network mask for this subnet.
- The last octet,10.2.2.254is the gateway for this subnet.
