Minimum number of VLANS tag required for the 5 VLANS on a single interface of F5

Hi Nishal,

For a better understanding of the Untagged, referer to this link:

https://networkdirection.net/articles/network-theory/taggeduntaggedandnativevlans/

In your example:

1. The external net has the tagged network 10, so F5 tag the traffic to tag 10, creating a broadcast in this network with all interconnected devices, allowing communication with all hosts.

2.The internal net is untagged, The F5 send the traffic to the Switch untagged, The switch set the default vlan for untagged traffic, and interconect with other switch or host where are located the servers with the vlan tagged or untagged, it depends of your network configuration. So then the the broadcast domain is allowed to communicate all the host corresponding to the network configured in the self-ip created with the vlan untagged.
