IPv6

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 distances, an ISP may be required to put them together. From a network access perspective, they could be

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 vendor. The case is to learn how the switches that are part of the LAN network learn about and support Vlan operation: is there

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 the gateway, a connected nexthop ip address… whatif we configure this static routing using an intermediate address: an address of a nexthop that

In this lab we implement a basic security architecture to demonstrate the operation of a firewall cluster to protect our network. Our “security domain” is segmented into four zones: Our security topology is compound by two security gateways (SG) that are managed by a single security manager server (SM). The SG gateways (firewall) are in

By definition, the BGP synchronization rule requires that when a BGP router receives information about a network from an I(nternal)-BGP neighbor, it does not use this information until a matching route : static or dynamic : learned via an IGP (Interior Routing Protocol like OSPF, that uses the default routing table (vrf0 or GRT, Global
