LInk controller 1600
Hi, basically link aggregation is configured between two unique equipments and cannot cross equipments, but you have alternative solution:
If your router interfaces are LAN interfaces like in many cisco ISR routers , then you can use them as such:
- Create two VLANS in F5: VLAN_ISP1 & VLAN_ISP2
- In each F5 take an interface (let's assume 1.1) assign it to VLAN_ISP1 and connect it to your ISP1 router
- Do the same thing for a second interface (1.2) with VLAN_ISP2 and connect to ISP2 router
You will then have used both interfaces for extra redundancy without using link aggregation. This is for the outside part.
For your inside switches, if you want extra redundancy, you can use a full mesh topology where every F5 has a port connected to each switch, and a trunk link is connecting the switches. In this scenario you must ensure Spanning Tree is running and that the trunk link between the switches is always in STP forwarding state.
