Configuration/IP/ RIP2 Subnets

Note: RIP-1 and RIP-2 are NOT supported.

To create or modify a global RIP2 route.

To modify a RIP2 route, click the Modify button.

RIP2 Global

RD Index

Routing doman index.

IP Address

The IP Address of this system on the indicated subnet. For unnumbered interfaces, a unique internal identifier is used.

Authentication Type

The type of Authentication used when receiving RIP packets on this interface.  

Values:

noAuthentication: no authentication is performed

simplePassword:  a clear text password is used in zhRip2IfConfAuthKey.

md5: an MD5 string is used in zhRip2IfConfAuthKey (see RFC 1321)

Authentication Key

The value to be used as the Authentication Key whenever the corresponding instance of Authentication Type has a value other than noAuthentication.

Send Type

What the router sends on this interface.

Values:

doNotSend:  no RIP updates are sent out on this interface.  

ripVersion1: RIP updates compliant with RFC 1058 are sent.

rip1Compatible: implies broadcasting RIP-2 updates using RFC 1058 route subsumption rules.  

ripVersion2: implies multicasting RIP-2 updates.  

ripV1Demand:  indicates the use of Demand RIP on a WAN interface under RIP Version 1 rules.

ipV2Demand: indicates the use of Demand RIP on a WAN interface under Version 2 rules.

Default: rip1Compatible

Receive Type

ich version of RIP updates are to be accepted.  

Values:

rip1: only RIP updates compliant with RFC 1058 are received.  

rip2: specifies to receive IP updates compliant with RFC 1388 only.

rip1OrRip2: allows reception of RFC 1058 and RFC 1388 compliant RIP updates.  

doNotReceive: the intreface accepts no RIP updates.  Note that rip2 and rip1OrRip2 implies reception of multicast packets.

Default: rip1OrRip2

Default Metric

The metric that is to be used for the default route entry in RIP updates originated on this interface.  A value of zero indicates that no default route should be originated; in this case, a default route via another router may be propagated.  The default is set using the metric in the received update.

Source IP Address

The IP Address this system will use as a source address on this interface.  If it is a numbered interface, this MUST be the same value as the IP address.  On unnumbered interfaces, it must be the value of IP address for some interface on the system.

Advertise Static Route

Specifies whether to advertise static routes.

Values:

none: no static routes are advertised.

low: only low preference static routes are advertised. Low preference routes are default routes.

high: only high preference static routes are advertised

both: advertise both low and high preference static routes

Default: none

Poison Reverse

Specifies whether to send poison reverse updates on this interface.  Poison reverse updates are used to prevent larger loops within the network by setting the metric (cost) of neighboring routes to infinity.  This will prevent two-hop loops.

By default, RIP uses a technique called split horizon to avoid routing loops and allow smaller update packets. Split horizon specifies that when a RIP update is sent out a particular network interface, it should not include routing information acquired over that same interface.  Poison Reverse is a variation of the split horizon technique that specifies that all routes are included in an update out a particular interface, but that the metric is set to infinity for routes acquired over that interface.  One drawback is that routing update packet sizes are increased when using poison reverse.

Setting the value of this object to Disable prevents poison reverse updates, where Enable allows poison updates to be sent on this interface.  

Default: Disabled
