IOS 12.4 Commands for RIP
auto-summary – auto-summarization across classful boundaries
default-information originate – generates a quad-zero route into the RIP domain
default-metric – metric to assign to redistributed routes
flash-update-threshold – suppresses flash/triggered updates if interval is less than threshold
input-queue – packet buffer, tweak higher to prevent overflow on slow routers
ip rip authentication key-chain – enables authentication and defines which key-chain to use
ip rip authentication mode – sets plaintext or MD5 authentication
ip rip receive version – override “version” to accept v1, v2, or both
ip rip send version – override “version” to send v1, v2, or both
ip rip triggered – enable triggered extensions to RIP on interface, partially RFC2091-compliant
ip rip v2-broadcast – broadcast to 255.255.255.255 instead of multicast RIP updates
ip split-horizon (RIP) – enable split-horizon; enabled by default except on frame-relay + SMDS
ip summary-address rip – enables summarization on an interface; overrides auto-summarization
neighbor (RIP) – unicast RIP updates to a specific router
network (RIP) – enables RIP updates on interfaces matching classful network
offset-list (RIP) – artificially add hop-count to inbound or outbound RIP updates
output-delay – tweak RIP update inter-packet delay in milliseconds
router rip – starts the router’s RIP process
show ip rip database – show all routes known to RIP including summaries and auto-summaries
timers basic (RIP) – tweak update, invalid, holddown, and flush timers
validate-update-source – forces RIP neighbors to be on the same network
version – globally sets v1 or v2 for both send & receive
Believe it or not, this was a good exercise. I saw some commands that I might have seen before, but don’t remember if I did. Like so many things in life, writing this little article sent me off on several little rabbit trails, where I had to check into what “ip rip triggered” actually meant, and what a “flash update” really was. What’s scary is that RIP is one of the smaller command sets to review. How many rabbit trails will there be to go down when I start “10 Words” on BGP, OSPF, or QoS? :-D
