ClusterXL supports Dynamic Routing for both Unicast and Multicast traffic. Dynamic Routing protocols, such as OSPF, BGP, or PIM, can be configured on cluster members to exchange routing information with other routers. ClusterXL supports two modes of operation for Dynamic Routing: New Mode and Legacy Mode.

The valid authentication methods for mutual authenticating the VPN gateways are Pre-shared Secret and PKI Certificates. Pre-shared Secret is a method that uses a secret key that is known only to the two VPN gateways. PKI Certificates is a method that uses digital certificates that are issued by a trusted Certificate Authority (CA) and contain the public key of each VPN gateway. Both methods ensure that the VPN gateways can verify each other's identity before establishing a secure VPN tunnel. Reference: [Check Point R81 VPN Administration Guide]

The inspection point Big l is the first point immediately following the tables and rule base check of a packet coming from outside of the network. It is also the last point before the packet leaves the Security Gateway to the internal network1. The other inspection points are either before or after the rule base check, or in a different direction of traffic flow2.
