Static routing is supported by CKP (Checkpoint firewalls or gateways). Let’s recall that a static route defines a destination subnet or network and the way to reach it: the outgoing interface on...
In this post, we explore the operation of Cisco FabricPath (FP) and more specifically Vlan information propagation in this fabric in comparison with other platforms: Catalyst for example from the same...
The simplest way to interconnect 3 or more routers in the same broadcast domain (and the same subnet) is by attaching them to a switch (or hub) in the same vlan. In case they’re separated by long dist...
