Hi Team,

We have multiple VLANs I want to know what security feauters we can use to block traffic between two VLANs i.e. Admin VLAN should not able to communicate with IT VLAN?

Thanks

You could use separate VRs (virtual routers). Depending on which routers you have, those are the ones that need to support VRs. A typical scenario is to have management (in-band and out-of band) in a separate VR and have all other VLANs in another VR. What switches/routers do you have in your core?

We have firewalls however they are edge firewall and Cores are doing the all routing. Do we need to add ACLs on the Cores if yes do you have a guide for the ACLs?

I hope they are 😉
Well then you need to either configure ACLs on your routers or purchase a firewall.

We have Core switches which are doing all the routing and currently I can ping and connect to all hosts? Both VLANs are on different IP ranges.

Unless you are using a router to communicate between those VLANs there won't be any traffic between them anyway.
