command)
Then initiate the RIP protocol (use router rip command) and configure the segment
(use network command) and set RIP protocol parameter on corresponding interfaces,
such as the option between RIP-I and RIP-II
After that, one feature of RIP protocol should be noticed ---the Layer 3 switch
running RIP protocol sending route updating messages to all neighboring Layer 3
switches every 30 seconds. A Layer 3 switch is considered inaccessible if no route
updating messages from the switch is received within 180 seconds, then the route to
the switch will remains in the route table for 120 seconds before it is deleted. Therefore, if
to delete a RIP route, this route item is assured to be deleted from route table after 300
seconds.
When exchanging routing messages with CE using RIP protocol on the PE router,
we should first create corresponding VPN routing/transmitting examples to associate with
corresponding interfaces. Then enter the RIP address family mode configuring
corresponding parameters.
If the RIP routing problem remains unresolved, please use debug rip command to
record the debug message in three minutes, and send them to our technical service
center.
