DC1 BIG-IQ DCD routing analysis

This routing analysis examines the routing table for the BIG-IQ DCDs in data center 1(DC1). The discussion references diagrams and tables that you can link to below.
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 A13. The static route goes from the eth1 NIC in DC1 to the discovery subnet in DC2. It is specified in the table as:
10.101.101
.0 255.255.255.0 10.1.1.254
  • The first octet
    10.101.101
    .0
    specifies the destination IP address used to communicate with the Discovery subnet in DC1.
  • The next octet
    255.255.255.0
    specifies the network mask for this subnet.
  • The last octet,
    10.1.1.254
    is the gateway for this subnet.
This route uses the Discovery subnet to go from the DCDs in DC1 to the BIG-IQ systems and DCDs in DC2. As the subnet name implies this route is mostly used for discovery, but also plays a role in disaster recovery scenarios.
eth1 interface to DC2 BIG-IP devices on the Discovery subnet
The entry for this route is in cell A14. The static route for the eth2 NIC is
10.104.104
.0 255.255.255.0 10.1.1.254
.
  • The first octet
    10.104.104
    .0
    specifies the destination IP address used to communicate with the cluster subnet in DC2.
  • The next octet
    255.255.255.0
    specifies the network mask for this subnet.
  • The last octet,
    10.1.1.254
    is the gateway for this subnet.
This route uses the Discovery subnet to go from the BIG-IQ systems in DC1 to the BIG-IP devices in DC2. As the subnet name implies this route is mostly used for discovery, but also plays a role in disaster recovery scenarios.
eth1 interface to DC1 BIG-IP devices on the Discovery subnet
The entry for this route is in cell A15. The static route for the eth2 NIC is
10.4.4
.0 255.255.255.0 10.1.1.254
.
  • The first octet
    10.4.4
    .0
    specifies the destination IP address used to communicate with the cluster subnet in DC2.
  • The next octet
    255.255.255.0
    specifies the network mask for this subnet.
  • The last octet,
    10.1.1.254
    is the gateway for this subnet.
This route uses the Discovery subnet to go from the BIG-IQ systems in DC1 to the BIG-IP devices in DC1. As the subnet name implies this route is mostly used for discovery, but also plays a role in disaster recovery scenarios.
eth2 interface to DC2 DCDs on the Cluster subnet
The entry for this route is in cell A16. The static route for the eth2 NIC is
10.102.102
.0 255.255.255.0 10.2.2.254
.
  • The first octet
    10.102.102
    .0
    specifies the destination IP address used to communicate with the cluster subnet in DC2.
  • The next octet
    255.255.255.0
    specifies the network mask for this subnet.
  • The last octet,
    10.2.2.254
    is the gateway for this subnet.
This route uses the Cluster subnet to go from BIG-IQ in DC1 to the BIG-IQ and DCDs in DC2. DCDs in DC1 use this route to exchange and manage data stored on DCDs in DC2. This route also plays a role in disaster recovery scenarios.
eth3 interface to DC2 BIG-IPs on the Listener subnet
The entry for this route is in cell A17. The static route for the eth3 NIC is
10.5.5
.0 255.255.255.0 10.3.3.254
.
  • The first octet
    10.5.5
    .0
    specifies the destination IP address used to communicate with the listener subnet in DC2.
  • The next octet
    255.255.255.0
    specifies the network mask for this subnet.
  • The last octet,
    10.3.3.254
    is the gateway for this subnet.
This route uses the Listener subnet to go from BIG-IQ DCDs in DC1 to the BIG-IP devices in DC1. DCDs in DC1 use this route to communicate event, alert, and performance analytics data generated by BIG-IP devices in DC1. This route also plays a role in disaster recovery scenarios.
eth3 interface to DC2 BIG-IPs on the Listener subnet
The entry for this route is in cell A18. The static route for the eth3 NIC is
10.105.105
.0 255.255.255.0 10.3.3.254
.
  • The first octet
    10.105.105
    .0
    specifies the destination IP address used to communicate with the listener subnet in DC2.
  • The next octet
    255.255.255.0
    specifies the network mask for this subnet.
  • The last octet,
    10.3.3.254
    is the gateway for this subnet.
This route uses the Listener subnet to go from BIG-IQ DCDs in DC1 to the BIG-IP devices in DC2. DCDs in DC1 use this route to communicate event, alert, and performance analytics data generated by BIG-IP devices in DC2. This route also plays a role in disaster recovery scenarios.
