Hi group,

 

Vol1 Section 19 task 9. Maybe I’m reading to much between the lines, but I
think the solution in the PG violates the task. The task requires to deny
jpeg files from being sent to stations on VLAN67.

 

1.     small typo, there is no VLAN67, I guess it should be VLAN567 (network
150.100.220.0/24)

2.     The policy-map is only applied to the two EthernetInterfaces. But
these stations could also be reached over the s0/1/0 interface, so should we
not apply the policy-map there as well?

3.     The PG matches jpeg based on mime types. Well, that’s great but the
task requires to deny jpegs sent TO stations on VLAN567. With the solution
provided in the PG, jpeg files sent to all possible networks reachable via
these interfaces will be dropped, isn’t it? I used the following solution:

 

R6

!

access-list 101 permit ip any 150.100.220.0 0.0.0.255

!

class-map match-all jpeg2vlan567

 match access-group 101

 match protocol http mime "image/jpeg"

!

policy-map denypics

 class jpeg2vlan567

   drop

!

int fa0/1

 service-policy output denypics

int fa0/0

 service-policy output denypics

int ser0/1/0

 service-policy output denypics

!

 

regards

 

Roger
