An engineer configures routing between all routers and must build a configuration to connect R1 to R3 via a GRE tunnel. Which configuration must be applied?
To configure a GRE tunnel between R1 and R3, we need to set the tunnel source and destination to be the loopback interfaces of the respective routers, as these are typically used in such configurations for stability and ease of routing. On R1, the tunnel source should be Loopback0 and the destination should be the Loopback0 of R3. On R3, the tunnel source should be Loopback0 and the destination should be the Loopback0 of R1. The option B correctly configures the tunnel interfaces on both routers, setting the appropriate IP addresses and using the loopback interfaces as sources and destinations.
Correct
A - Wrong - Tunnel destination is itself B - Correct - Since the question says "An engineer configures routing between all routers" we must assume the Loopbacks are being advertised, so we can use them as source / destination. C - Wrong - Doesn't make sense since we have a tunnel from R1 to R2 D - Wrong - Tunnel destination is itself
what the f is this, all interface IPs are wrong...
Yep its pretty bad.
B is correct
