Hello Everyone !
I understood what is Layer2 forwarding VS & how it works but could someone explain what are the use case scenarios for Layer2 Forwarding VS ? Has anyone deployed this ?
Have you looked at Lori MacVittie's (F5) article, Back to Basics: The Many Modes of Proxies? It provides some information on L2 Forwarding Virtual Servers. Basically, it is not uncommon for a BIG-IP system to be placed in a network location where it sits in the path between two existing networks. As a default-deny system, any traffic that is not explicitly allowed by the BIG-IP system's configuration is denied. Therefore, if access is needed between networks where the BIG-IP system is in the path, a forwarding virtual server provides an ideal solution. A forwarding virtual server essentially changes your BIG-IP system from full-proxy mode to packet-by-packet proxy mode, at least for the traffic the forwarding virtual server processes:
The BIG-IP system provides forwarding services in two ways:
Does this help?
Thank you crodriguez ! i will check that article.
i have gone through the article but i didn't get the where this can be used ? if it's like a network bridge will the L2 VS forwards the packet based on destination MAC ? i'm not sure how this works.
Try this article for some additional detail on VLAN groups and how a Forwarding L2 can work under the covers to bridge clients and servers in the same address space but different VLANs: https://devcentral.f5.com/questions/vlan-group-23088
Can I ask better way?
using L2 forwarding.
using L3 forwarding & change db vlangroup.forwarding.override value false?
