Configure the ACME Headquarters network (AS 12345) & New York Office (34567) as per the following requirements. 1. 2. 3. 4. 5.

The VTP domain must be set to CCIE Use VTP version 2 SW1 must be the VTP server and SW2 must be the VTP client Secure all VTP updates with an MD5 digest of the ASCII string "CCIErocks$” SW3 & SW4 must not advertise their VLAN configuration but must forward VTP advertisement that they receive out on their trunk ports. 6. In order to avoid as much as possible unknown unicast flooding in all vlans the administrator requires that any dynamic entries learned by other SW1 and SW2 must be retained for 2 hours before being refreshed.

Configure All Switch Ports as per the following requirements :1. Complete the configuration of all vlans so that all routers that are located in ACME's headquarters (AS12345) and New York office (AS 34567) can ping their directly connected neighbors. 2. All four switches (SW1-SW4) must have four dot1q trunks that do not rely on negotiation DO NOT configure any ether channel 3. Ensure that the following unused ports on all four switches are shutdown and configured as access ports in vlan 999 E3/0 - E3/3 are unused on SW1 and SW2 E1/0 - E1/3 are unused on SW3 and SW4 E3/0 - E3/3 are unused on SW3 and SW4

Configure the ACME network as per the following requirements. 1. 2. 3. 4. 5.

SW1 must be the root switch for all odd vlans and must be the backup for all even vlans SW2 must be the root switch for all even vlans and must be the backup for all odd vlans SW3 must be the root switch for all odd vlans and must be the backup for all even vlans SW4 must be the root switch for all even vlans and must be the backup for all odd vlans Explicitly configure the root and backup roles, assuming that other switches with default configuration may eventually be added in the network in the future

6. All Switches must maintain one stp instance per vlan 7. Use stp mode that has only 3 possible port states. 8. All access ports must immediately transitioned to the forwarding state upon link up and they must still participate in STP . Use single command per switch to enable this 9. Access ports must automatically shut down if they receive any BPDU and an administrator must still manually re-enable the port. Use a single command per switch to enable this feature.

Configure WAN Connectivity as per the following requirements 1. The WAN links must rely on a layer 2 protocol that supports link negotiation and authentication. 2.

R18 must use the username ACME-R18 and password CCIE 4. R19 must use the username ACME-R19 and password CCIE

Ensure that all the BGP next-hop is never marked as unreachable as long as interface loopback0 of the remote peer is known via IGP

Configure EBGP in AS 34567 according to the following requirements 9. All four BGP routers must establish EBGP peering with their neighboring AS as shown in diagram 3 (BGP topology) 10. All four BGP routers must redistribute EIGRP into BGP 11. R9 and R11 must redistribute only the BGP default route into Eigrp 12. Ensure that R9 is the only router that sees the default as a BGP route and that all other routers (R8, R10, R11) see it as an EIGRP external router.

SW5 and SW6 must not establish any BGP session at any time. All BGP routers must use their interface loopback0 as the BGP router-id. No IBGP peering session are allowed in AS 45678. R15 must establish an EBGP peering with AS 10003 and must receive a default route as well as other prefix. R15 must redistribute BGP into EIGRP vice versa. R15 must also advertise an aggregate prefix for 123.20.1.0/24 to AS 10003 and must suppress all components prefixes. R16 , R17 , R18 , R19 must establish an EBGP peering with AS 20003 and must receive a default route as well as other prefix. R16 , R17 , R18 , R19 must not advertise any prefix to AS 20003. As long as R15 operational , R16 , R17 , R18 , R19 must prefer the EIGRP default route over the EBGP default route. Do not create any VRF in anywhere in order to accomplish the above requirements.

Refer to "diagram 3 BGP topology" and "diagram 4 VPN technology" The ACME HQ network (AS12345) uses MPLS L3VPN in order to clearly separate remote site networks The ACME corporate security policies are centralized and enforced at the San Jose site (AS 65112) for all remote sites. the policies require that all traffic that is originated from any remote sites (with the exception of New York office) Configure MPLS L3 VPN in the ACME network according to the following requirements

1. Enable LDP only on required interfaces on all seven routers in AS 12345 2. Use the interface loopback 0 to establish LDP peering 3. Ensure that no MPLS interface that belongs to any router in AS12345 is visible on a traceroute that originates outside of the AS 4. R2, R3, R6 and R7 must be configured as PE routers 5. R1, R4 and R5 must be configured as P routers

Refer to "diagram 3 BGP topology" and "diagram 4 VPN technologie" The global and regional service providers have agreed to transport the ACME VPN via PE to PE EBGP peering that are already preconfigured. Complete all the configuration of MPLS L3 VPN in the ACME network according to the following requirements

1. R1 must reflect VPNv4 prefixes from any PE to any other PE in AS 12345 2. R2 and R3 must establish EBGP peering with both global Service Providers (As 10001 and AS 10002) for the following VRF's     

GREEN BLUE RED YELLOW INET

3. R6 must establish an EBGP peering with the regional SP (AS 20001) for the following VRFs   

GREEN BLUE INET

4. R7 must establish an EBGP peering with the regional SP (AS 20002) for the following VRFs   

BLUE RED INET

5. All ip address used for EBGP peering must pass the BGP's directly connected check 6. No BGP speaker is AS 12345 may use the network or redistribute statement under any address-family of the BGP router configuration 7. At the end of the exam scenario the interface ethernet 0/0 of the gateway router in any remote site must be able to connect to the interface ethernet 0/0 of any other remote gateway that belongs to AS 65111 or AS 65222

Use AES encryption with the pre-shared key “ CCIE “ The key must appear in plain text in the configuration All IPsec tunnels must be authenticated using the same IKE Phase 1 pre-shared key Use 1024 bits for the key exchange using the Diffie-Hellman algorithm Configure a single policy using priority 10

2. Configure IKE Phase 2 as per the following requirements    

Use CCIEXFORM as transform-set name use DMVPNPROFILE as IPSEC profile name use IPSEC in transport mode use the IPSEC protocol ESP and algorithm AES with 128 bits

3. Ensure that the DMVPN cloud is secured using above parameters. 

Use tunnel protection in your configuration.
