HP 2920 Series User Manual

that contains a path with fewer hops than the path stored in the HP routing switch's route table,
the routing switch replaces the older route with the newer one. The routing switch then includes
the new path in the updates it sends to other RIP routers, including HP routing switches.
RIP routers, including HP routing switches, also can modify a route's cost, generally by adding to
it, to bias the selection of a route for a given destination. In this case, the actual number of router
hops may be the same, but the route has an administratively higher cost and is thus less likely to
be used than other, lower-cost routes. A RIP route can have a maximum cost of 15. Any destination
with a higher cost is considered unreachable. Although limiting to larger networks, the low maximum
hop count prevents endless loops in the network.
The switches support the following RIP types:
• Version 1
• V1 compatible with V2
• Version 2 (the default)
NOTE: If the routing switch receives an ARP request packet that it is unable to deliver to the final
destination because of the ARP timeout and no ARP response is received (the routing switch knows
of no route to the destination address), the routing switch sends an ICMP Host Unreachable message
to the source.
