On receiving the response, Local Traffic Manager then performs the reverse translation; that is, the system translates the pool member’s actual source address to the virtual server A Route Domain in F5 BIG-IP is essentially an isolated routing table. Maybe one more question to solidfy my thinking on this. Tap the Share icon to send the capture to an email address where you can receive the routing table as an email attachment. Since we are already sending all the traffic from the spoke VPC's to TGW, there is no need to change any of the routes inside the spoke VPC's. 5), which is a LB VIP configured on F5-Outbound, frontending resources in Server network. You must configure route advertisement to ensure that the dynamic routing protocols propagate this route to other routers on the network. Configuring the properties of each interface is one of the first tasks you do after running the Setup utility on the BIG-IP system. If it turns out that Router A’s routing table shows two routers that it can forward the data to reach 107. There is a concept of parent and child route domains, so while they’re similar to another routing concept you may be familiar with; I could create a static route to share, using F5 GUI or tmsh. Routing tables are stored in the routingTable submodules of hosts, and can be inspected in the runtime GUI. Subnet routing table - Each subnet may have its own routing table, we are using this capability to control traffic .
