Ipexperts, In various labs, I've noticed that you guys present a scenario where you have two eBGP nodes peering via a loopback that is being advertised via an IGP. Obviously, this is going to cause the neighbor to "flap" since the eBGP AD 20 metric will supersede any of the default IGP metrics. The two techniques I've seen you guys use throughout your workbooks are to either filter the loopback via route-map on the neighbor or playing around with the distances to make the IGP loopback preferable. The technique I always use and to me seems much simpler is just using the network statement with the keyword "backdoor" for the peer's loopback address. I haven't seen you use this technique and I'm wondering if there is a reason why? Obviously, if you have certain restrictions in a particular lab I wouldn't use it but, if there aren't any shouldn't this be a valid method as well?
I'm just wondering if there is some downside that I'm not seeing. Thanks -Rob _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
