Re: INE Workbook

Hello bilal,

The reason of the dummy route there is to ensure that the conditional default route is advertised only if there is reachability to the Ethernet segment of BB3. Even though the routers are connected on the same segment R4 has no way of detecting the remote end of the link is down. A DUMMY route is used together with an ip sla to test reachability to BB3. The default route is conditionally advertised only if the dummy route is in the routing table.

Hope this helps

Hi All,

I was doing INE workbook 1 and was bit lost in one of the technology lab.
The topic is RIPv2 Reliable Conditional Default Routing in which I couldn't
understand why DUMMY route was used to track the reachability of BB3. Any
thoughts -
