Hm.. community arrives at R3 but the route-map doesn't care. Still localpref 100 not 200.

INE WB Vol1 - 6.36 OSPF Reliable Conditional Default Routing

Hm... aha a placeholder-route to null0 with tracking-option and then match with a prefix-list on a route-map to originate the default route.


 But what the INE guys are missing that they don't state you can impelement a new IP subnet to the requirements.

My first try was to add a normal default-route to the backbone-device add a track statement on this route, and everything is fine !?!
A more "straightforward" solution thatn INE, it's not necessary to do it with a 169...-whatever !?!

What do you think ?

[SOLVED] WTF ? OSPF FULL ROUTING = TROUBLESHOOTING LAB

AutoInstall Using Frame Relay

If the new router is connected by a Frame Relay-encapsulated serial interface, AutoInstall will send a BOOTP request over the lowest numbered serial or HSSI interface. (The attempt to run AutoInstall over Frame Relay is performed only after attempts are made using SLARP over HDLC, DHCP, and RARP.)

The broadcast BOOTP request sent by the new router will contain the MAC address of the new router's interface. The staging router should be configured to forward the request using a helper address. A DHCP or BOOTP server will then return the IP address assigned to that MAC address. (Note that either a DHCP or BOOTP service can respond to the BOOTP request.)

AutoInstall using Frame Relay can be initiated over only the first serial interface on the new router. Specifically, Autoinstall over Frame Relay can be initiated over Serial 0 (S0), or Serial 1/0 (S1/0). For example, if the new router has serial interfaces S1/0 through S1/3 and S4/0 through S4/3, AutoInstall will be attempted over S1/0 only and cannot be forced to be initiated from S4/0. If AutoInstall over S1/0 fails, an Frame Relay attempt will not be made from any other serial port.

Only a helper address and a Frame Relay map need to be configured on the staging router. No MAC-to-IP address map is needed on the staging router. For configuration details, see the "Configuring a Frame Relay-Encapsulated Serial Interface Connection" section.
