Managing Digital Racket
The more I tune out, the less I miss it. But that has presented me with some complex choices for a nuanced approach to curb

10 Words Or Less – RIP

347 Words. Plan about 2 minute(s) to read this.

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 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
