I'm looking for GNS3 file to simulate HSRP with two VLAN interfaces but failed to get the information. Finally, I managed to get through and I'll share soon.
Below is the topology diagram that I have simulated with GNS3.
Download completed GNS3 file from
https://docs.google.com/leaf?id=0B889ogd4ltI2NDBiMzg5YjItNTcwYi00ODhmLWJiYzItYWIyZjk5ZDM3YjU3&hl
Here is brief description of lab topology.
- R1 and R2 are HSRP active and standby routers for VLAN 100 and VLAN 200.
- R3 is the layer 2 switch and enabled trunk in fa1/1 and fa1/2 to allow traffic from R4 (VLAN-100 PC) and R6 (VLAN-200 PC)
- R1, R2 and R5 are in EIGRP 1 network and ip routing is enabling all routes including loopback of R5 (5.5.5.5).
- Simple testing can be done by ping from VLAN 100 PC (R4) to R5's loopback ip 5.5.5.5
- To simulate HSRP, try to track loopback of R1's interface status. When it's down, R1 will release it's active role to R2 for VLAN 100.
- With same method, for VLAN 200, configure R2 as active role in VLAN 200. Track loopback 0 of R2's interface status. When it down, R2 will release it's active state for VLAN 200 to R1.
- By doing so, both VLAN 100 and VLAN 200 will be online all the time even though any of either R1 or R2 down for redundancy.
Detail of configuration steps are as follows;
R1(config)#int fa1/1
