- Trouble Ticket # 1
The NAT ACL needs to be reconfigured. The correct configuration is as follows:
ip access-list extended NAT-ACL
permit ip 10.1.1.0 0.0.0.255 anyThis prevents all traffic from being NATd, which is breaking the routing.
- Trouble Ticket # 2First, R1 is not advertising any routes to R2 because it has been configured to filter all LSAs. The ip ospf database-filter all out command applied under the FastEthernet0/0 interface of R1 must be removed. This prevents R4 from receiving any routes from R1, which in turn prevents R4 from advertising those to other routers in the domain.
Second, the issue is that the tunnel encapsulations are mismatched on R1 and R4. The tunnel interface on R4 should also be configured to use the ipv6ip tunnel encapsulation. The interfaces will be in the up/up state; however, you will not be able to ping across the tunnels.
- Trouble Ticket # 3First, the subnets keyword is missing from the redistribute command. This needs to be added; without this keyword, subnets are not injected into the OSPF process
Second, the configured summary address is incorrect. This needs to be changed to 180.3.0.0 255.255.252.0 instead of 180.3.0.0 255.255.255.252.
- Trouble Ticket # 4First, the default gateway in the DHCP pool is incorrect. This should be changed to 10.4.4.1
Second, DHCP option 150, not 160 is required to provide the IP phones with the TFTP server address. Option 160 should be removed and replaced with Option 150 instead.
Third, the DHCP service has been disabled globally. This should be enabled by issuing theservice dhcp command on R4.
