RIP 95
■ MD5 authentication — This mode uses two packet formats: One format
follows RFC1723 (RIP Version 2 Carrying Additional Information); the other
format follows RFC2082 (RIP-2 MD5 Authentication).
Perform the following configuration in VLAN interface view
The usual packet format follows RFC1723 and nonstandard follows RFC2082.
Configuring Split Horizon
Split horizon means that the route received through an interface will not be sent
through this interface again. The split horizon algorithm can reduce the
generation of routing loops, but in some special cases, split horizon must be
disabled to obtain correct advertising at the cost of efficiency. Disabling split
horizon has no effect on the P2P connected links but is applicable on the Ethernet.
Perform the following configuration in VLAN interface view.
By default, split horizon of the interface is enabled.
Enabling RIP to Import Routes of Other Protocols
RIP allows users to import the route information of other protocols into the
routing table.
RIP can import direct and static routes.
Table 92 Setting RIP-2 Packet Authentication
Operation Command
Configure RIP-2 simple authentication key rip authentication-mode simple
password-string
Configure RIP-2 MD5 authentication with
packet type following RFC 1723
rip authentication-mode { simple
password | md5 { usual key-string
| nonstandard key-string key-id }
}
Configure RIP-2 MD5 authentication with
packet type following RFC 2082
rip authentication-mode { simple
password | md5 { usual key-string
| nonstandard key-string key-id }
}
Set the packet format type of RIP-2 MD5
authentication
rip authentication-mode { simple
password | md5 { usual key-string
| nonstandard key-string key-id }
}
Cancel authentication of RIP-2 packet undo rip authentication-mode
