Configuring IP, ARP, RIP, and OSPF Services

If a subnetwork on the router has the same mask as the associated address, RIP V1

will advertise that subnet over the unnumbered interface. If the mask on the

subnetwork is different from the mask of the associated address, RIP V1

advertises only the natural network of the subnet.

BGP peers, NetBIOS, and BootP cannot be configured directly on an unnumbered

interface. To configure a BGP peer-to-peer session on routers connected through

unnumbered interfaces, see Configuring IP Exterior Gateway Protocols (BGP and

EGP). To route NetBIOS packets over an unnumbered interface, you must

configure a static entry to the name server. To run BootP over unnumbered

interfaces, you must select a preferred BootP server. For instructions, see

Configuring SNMP, BootP, DHCP, and RARP Services.

Using the Alternate Associated Address Option

The alternate associated address option ensures that a network on an unnumbered

interface remains reachable. IP automatically assigns an alternate associated

address to an unnumbered interface in the event that the primary associated

address goes down. IP uses the first available interface.

Note:

Bay Networks recommends that you select RIP2 mode for unnumbered

interfaces. With RIP2, RIP updates contain both the route and mask

information.

Note:

If an associated address becomes unreachable, some functionality may

be lost for certain protocols over the unnumbered interface.
