Self IP and Virtual IP

Hi,   Like to know about the relationship between self ip and the virtual ip in F5? Of course I did read the article (https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos-routi...

If you had a chance to work with routers or multilayer switches then self-ip address is analog of ip address of SVI interface.

 

Loopback IP is similar to VIP IP (it is very rough though). But on big-ip self-ip and VIP ip share the same MAC of the VLAN they belong to.

 

VIP is dataplane

 

self-ip is sort of control plane

 

All service traffic goes via virtual IPs only. Device control traffic goes via self-ips only.

 

I hope that make sense. If not, please provide more details what you are looking for.
