1304.0. "Rip support IP uunmber?" by HGOM22::DAVYSUN () Fri May 09 1997 03:07

    Hi,
    
    As we all know,Brouter90 support IP unnumber .
    
    But could Rip support IP unnumber?
    
    
    Thanks for your answer!
    
    Regards!

1304.1RIP works over IP unnumbered interfacesFOUNDR::SHEEHANMon May 12 1997 15:1899
 Hi Davy,

 On the DECbrouter if you set the interface as unnumbered Ethernet 0
 and the network you want RIP to send and recieve updates on as the
 IP network the Ethernet interface is in on the routers on both sides
 of the WAN connection then RIP routing updates will work fine.

 Regards,
                              o

From the Docs...

The network number specified must not contain any subnet
information. You can specify multiple network commands.
RIP routing updates will be sent and received only through
interfaces on this network.

RIP sends updates to the interfaces in the specified
network(s). Also, if an interface�s network is not specified, it
will not be advertised in any RIP update.

Example

The following example defines RIP as the routing protocol to
be used on all interfaces connected to networks 128.99.0.0
and 192.31.7.0:

router rip
network 128.99.0.0
network 192.31.7.0
