Per the split-horizon rule, don’t send an update back on the interface it was received on
What is the challenge here? In addition to bandwidth usage and system resources consumption, Split horizon helps prevent routing loops…
In this kind of loop the routing information is lost, incoherent between the domain routers
Continue reading “Is it sufficient split-horizon rule to prevent RIP loops?”In RIP domain routers R1 and R2 exchange information about loopback 0 and 1 networks
Router RIP command “network 0.0.0.0” hints routers to add all ip enabled interfaces to the update list and include their “subnets” into this update
Continue reading “RIP: do not split it then… and unleach the power of the “network” command”Both R1 and R3 advertise 13.13.13.13/32 network into RIP domain
R3 is configured to offset all network updates via interface fa1/0 by 10

It is not possible to configure a static route with an intermediate address in a Check Point security gateway.
