Hi All,
This is from lab one, (which also makes up the free sample lab) the question is:
--- Configure a new Loopback interface on R1 with the IP address
150.X.11.1/24 and advertise it into BGP.
--- Configure AS 200 so that all traffic from AS 100 destined to this
prefix traverses the Ethernet segment between SW4 and R5.
--- In the case that the link between SW4 and R5 is down traffic
destined for the 150.X.11.0/24 prefix should transit the Frame Relay
link between R2 and R3.
--- Do not use AS-Path prepending to accomplish this.
So basically a BGP route is coming in from 2 different EBGP peers into
AS 200 and you need to perfer one route over the other. The solution
guide modifies the metric to answer this.
But what I did was to modify the origin to incomplete on one of the
peers (less preferred peer). I believe this answer would also be vaild
would you agree? If not, how come?
Thanks
Az
