Web Field/UCI/Package Option
Description
Web: Interface
UCI: ripd.@interface[0].rip_interface
Opt: rip_interface
Specifies the interface name.
Web: Split Horizon
UCI: ripd.@interface[0].split_horizon
Opt: split_horizon
Prohibits the router from advertising a route back onto the
interface from which it was learned.
0
Disable.
1
Enable.
Web: Poison Reverse
UCI: ripd.@interface[0].poison_reverse
Opt: poison_reverse
Router tells its neighbour gateways that one of the gateways is
no longer connected. Notifies the gateway, setting the hop count
to the unconnected gateway to 16 which would mean "infinite".
0
Disable.
1
Enable.
Web: Passive
UCI: ripd.@interface[0].passive
Opt: passive
Sets the specified interface to passive mode. On passive mode
interface, all receiving packets are processed as normal and ripd
does not send either multicast or unicast RIP packets except to
RIP neighbour specified with a neighbour command.
0

1

Web: Authentication
UCI: ripd.@interface[0].auth_mode
Opt: auth_mode
RIPv2 (only) allows packets to be authenticated via either an
insecure plain text password, included with the packet, or via a
more secure MD5 based HMAC (keyed-Hashing for Message
AuthentiCation). Enabling authentication prevents routes being
updated by unauthenticated remote routers, but still can allow
routes, that is, the entire RIP routing table, to be queried
remotely, potentially by anyone on the internet, via RIPv1.
no
Default value. No authentication.
md5
Sets the interface with RIPv2 MD5 authentication.
text
Sets the interface with RIPv2 simple password
authentication.
Web: Text Auth. Key
UCI: ripd.@interface[0].auth_key
Opt: auth_key
This command sets the authentication string for text
authentication. The string must be shorter than 16 characters.
Web: MD5 Key Chain Name
UCI: ripd.@interface[0].key_chain
Opt: key_chain
Specifiy Keyed MD5 chain.
Table 83: Information table for RIP interface configuration
22.3.4
MD5 authentication key chains
RIPv2 (only) allows packets to be authenticated using either an insecure plain text
password, included with the packet, or by a more secure MD5 based HMAC (keyed-
Hashing for Message AuthentiCation). Enabling authentication prevents routes being
updated by unauthenticated remote routers, but still can allow routes, that is, the entire
RIP routing table, to be queried remotely, potentially by anyone on the internet, using
RIPv1.
This section defines key_chains to be used for MD5 authentication.
