Hi I would need a helping hand to understand the following: Task: Configure R2 within AS1 to deny any traffic arriving from outside AS1, but with a source IP address located within AS1 My solution would have been to solve this via RPF strict mode as we have no asymetric path here. But: The proctor guide solves this with an access-list which is in my opinion incomplete (loo 0 of R5 and /30 link to AS2 is missing) Furthermore I don't understand the wildcard mask for the network 150.50.24.0/30 which is in the guide 150.50.24.2 0.0.2.0 ? Is this a typo or do I miss something here. For me the wildcard-mask should be 150.50.24.2 0.0.0.0 as 0.0.0.3 would block also the ebgp source address from AS3. thanks for any help best regards peter
