Section 1.3 Spanning Tree
Configure the ACME network as per the following requirements
l Assign all active odd vlans to instance 1
l Assign all active even vlans to instance 2
l Ensure that sw1、sw3 is the primary root bridge for odd vlans
l Ensure that sw1、sw3 is the secondly root for even vlans
l Ensure that sw2、sw4 is the primary root bridge for even vlans
l Ensure that sw2、sw4 is the secondly root for odd vlans
l explicitly configure the root and backup roles, assuming that other switches with
default configuration may eventually be added in the network in the future
l all access ports must immediately translation to the forwarding state up on link up and they must still participate in stp. use single command per switch to enable this
l 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.

instance 2 vlan 14, 24, 46
SW3/SW4
spanning-tree mode mst
spanning-tree mst configuration
instance 1 vlan 1,49, 89, 111, 411, 999
instance 2 vlan 34, 38, 310
SW1/SW3
spanning-tree mst 1 priority 0
spanning-tree mst 2 priority 4096
SW2/SW4
spanning-tree mst 1 priority 4096
spanning-tree mst 2 priority 0
SW1/SW2/SW3/SW4
spanning-tree portfast default
spanning-tree portfast bpduguard default
Section 1.4 WAN Switching
l The WAN links must rely on a layer 2 protocol that supports link negotiation and authentication.
l The Service provider expects both R18 and R19 to complete three-way handshake by providing the expected response of a challenge that is send by AS 20003 Router.
l R18 must use the username ACME-R18 and password CCIE
l R19 must use the username ACME-R19 and password CCIE
Solution：
R18
interface Serial4/0
encapsulation ppp
ppp chap hostname ACME-R18
ppp chap password CCIE
/-- Pay attention to check the username and password on the exam. --/
R19
