RIP
RIP Implementations RIPv1 Original RIP implementation, limited to classful routing (obsolete) RIPv2 Introduced support for classless routing, authentication, triggered updates, and multicastannouncements (RFC 2453) RIPng (RIP Next Generation) Extends RIPv2 to support IPv6 routing (RFC 2080); functions very similarly to RIPv2 and is subsequently as limited Protocols Comparison

Route Poisoning When a network becomes unreachable,an update with an infinite metric is generated to explicitly advertise the route as unreachable Poison Reverse
A router advertises a network as unreachable through the interface on which it waslearned

RIPv2 Configuration
! Enable RIPv2 IPv4 routing router rip version 2 ! Disable RIPv2 automatic summarization no auto-summary ! Designate RIPv2 interfaces by network network network ! Identifyunicast-only neighbors neighbor IP-address ! Originate a default route default-information originate ! Designate passive interfaces passive-interface {interface | default} ! Modify timers timers basicupdate invalid hold flush

Timer Defaults Update 30 sec Invalid 180 sec Flush 240 sec Hold-down 180 sec
