Download Lab: GNS3 | EVE-NG |
Prerequisites:
Cisco IOSv (vios-adventerprisek9-m.vmdk.SPA.156-2.T)
Cisco IOSvL2 (vios_l2-adventerprisek9-m.03.2017.qcow2)
GNS3 AAA Server Download
Note:
Since prerequisite for these labs are Cisco VIRL images, Frame Relay Cloud in original topology from the Cisco will be replaced by IOSvL2 switch and configured appropriately to imitate sub-interfaces for the point-to-point links. Access to the Cloud not available. All interfaces on the Cloud are configured as 802.1q Trunk, permitting VLAN 12,23,34.
Objective:
Apparently, there is the suspicion that traffic flow from VLAN 10 is suboptimal when you access Web Server, you need to investigate and solve the problem.
Client1 PC's MAC address appears on the ASW2 MAC address table when PC ping 209.65.200.241.

Total Mac Addresses for this criterion: 4

Topology:
Instruction:
Open terminal to both Clients PCs and obtain an IP address via DHCP, by typing "ip dhcp" command. Sometimes you need to execute this command twice to obtain an IP address and to eliminate possible DHCP related problems.
Attempt to ping Web server then check if there is Client1's MAC Address in the ASW2 MAC address table.
Clear CAM table of ASW2 and ARP cache on Client1. For VPCS to clear ARP cache use "clear arp" command.
Troubleshoot the issue, if resolved there should no presence of that MAC Address in CAM table of ASW2 after you ping Web Server again, as long as Client1's ARP cache contains its default gateway MAC address.
Validation:
Absence of Client1's MAC address in ASW2 CAM table will prove that the problem is resolved.
