Internet Protocol (IP) Routing
•
The message includes the required authentication information. This means that the Address
Family Identifier field of the first entry in the message must have a value of 0xFFFF, the
Authentication Type field of the first entry must have a value of 2 (a value of 1 indicates no
authentication), and the Authentication field must contain a 16-byte unencrypted password.
•
The password in the message matches the value of the rip_auth parameter.
The Model 5390 server accepts all RIP 2 messages it authenticates, but does not necessarily discard
all unauthenticated messages it receives.
Table A12-9 shows how the Model 5390 server accepts or discards a RIP message depending on
whether or not the Model 5390 server and/or the message are configured for authentication and
whether or not the password in the message matches the rip_auth password.
Although RIP 2 authentication cannot protect your system against a user who has the physical means
or access to diagnostic tools to tap the network, it nevertheless prevents SLIP or PPP users from
injecting routes into the system.
Enabling and Disabling Active RIP
For active RIP to operate:
•
At least two Model 5390 interfaces must be operational.
•
Each SLIP, PPP, and Ethernet interface over which routing is to occur must have an IP
address.
