Hi group - ipexpert

 

I’m just working on Section 12 and I figured out that there are a couple of
mistakes in the PG. To me, with the provided solution and also the final
configs, it would never work.

 

The task is to bring up a tunnel between R9 and R5. Before redistribution it
does not work (that’s clear). O.k. so in Task 7 we do redistribution between
EIGRP and OSPF on R6. Additionally, since we are not allowed to use a
network statement for the Loopback on R6, we do also have to configure a
redistribute connected into OSPF. The PG uses an ACL to specify only the
loopback:

 

R6

access-list 1 permit 210.6.6.6

route-map loop

 match ip address 1

!

router ospf 1 

redist connect subne route-map loop

 

Well, with this solution, the tunnel will never come up and the network
between R6 and R9 (172.31.69.0/30) will never be advertised throghout the
network, because the “redistribution-access list” on R6 blocks this network
since it is connected.

The access-list on R6 would have to look like:

 

access-list 1 permit 210.6.6.6

access-list 1 permit 172.31.69.0 0.0.0.3

 

The same happens on R7 for the RIP network between R7 and R8. The “loopback
ACL” on R7 permitts only the Loopback of R7, so the network for R7 to R8
would never be reachable by the others.

 

This would also violate the general task, that we must have full IP
connectivity.

 

I think it would be worth to adappt the PG and the final configs, isn’t it??

 

regards

 

Roger
