Ip Rip Authentication - Enterasys X-Pedition XSR CLI Cli Reference Manual

ip rip authentication

This command sets or deletes the single authentication key used for RIP authentication on the
interface. Authentication can be used only if a key exists. Deleting an existing key disables the use
of authentication for RIP.
Syntax
ip rip authentication key text
text
Syntax of the "no" Form
The no form of this command deletes the specified key and prevents RIP from using
authentication:
no ip rip authentication key text
Mode
Interface configuration:
Default
No authentication key
Example
The following example sets the authentication mode as text and the key text as phone on
FastEthernet port 1:
XSR(config)#interface fastethernet 1
XSR(config-if<F1>)#ip rip authentication key phone
XSR(config-if<F1>)#ip rip authentication mode text
RIP Example
The following example, as shown in Figure
Router 1, also enabling routing exchanges on the serial link Router 1‐Router 2 (Serial port 2).
Note: This type of filtering might prove problematic in situations where you want to filter an exact
route (for RIP v2). For example, if you want to filter route 10.0.0.0/8, a filter set as access-list 1
deny 10.0.0.0 0.255.255.255 will not suffice, because subnets such as 10.0.0.0/9, 10.0.0.0/
10 and so on will also be denied. So, to restrict the filter to 10.0.0.0/8 only, configure an extended
access list with the following format: access-list 101 deny 10.0.0.0 0.0.0.255
255.0.0.0 0.0.0.0
Identifies the key. Valid values are strings of 16 characters or less.
Spaces can be used if the complete key is bounded by quotations.
