Cisco Packet Tracer

[JFGUDUD]

 In this section, you must apply layer 3 redundancy, so the ISP router is always reachable. Do the following:

1. Enable HSRP on the appropriate interface of each of the two Gateway routers.
2. Assign highest HSRP priority to Gateway 1 (Active router)
3. Ensure that Gateway 1 becomes the active HSRP router again when the links comes back up.
4. Modify the default gateway on each PC to target the new HSRP router IP address.

5. Ping from both PCs to the server to verify connectivity and take note of the paths followed by the packet. You may use PDA packets.

   6. Disable interface Gig0/0 on Gateway 1 and Ping from both PCs to the server to verify that connectivity is still available. The paths should be different from the last simulation.

   7. Re-enable interface Gig0/0 on Gateway 1 and Ping from both PCs to the server. Verify that the packets go back through Gateway 1.

What is your question?

Hello,

change the default gateway on both PCs to 10.0.0.1, and use the configs below on the gateway routers:

how do i enable an hsrp on the pkt sent above?

[Georg Pauwen]

Hello,

not sure what you mean. What do you want to enable ? Did you configure the routers as stated ? The exec command:

sh standby

tells you the status of the HSRP.
