HSRP is not working between IOU switches. neither switch can see it's neighbor as a standby so they both remain active. I can not see any HSRP hello's being transmitted across the vlan.(tried using i86bi-linux-l2-adventerprisek9-15.1.bin image which does have Layer 3 functionality as well as i86bi-linux-l3-ipbase-12.4.bin which seems to only work as a router)

nevermind, looks to be a IOU issue

This is a known issue with any L2 IOU image.
Currently I think there is no available L2 IOU image on which HSRP works properly.

What is the name? ;)

I think GNS3 should come up with a list of recommended IOU images... So please share your experiences :)

Thanks,

Gladly,

Pulled the latest IOU images from http://certcollection.org/forum/topic/172857-current-iou-l2l3-linux-images/. The one I'm using that supports HSRP is i86bi_linux_l2-ipbasek9-ms.may8-2013-team_track

Just in case anybody is doubtful

Code:
Switch1(config-if)#do sh standby
Vlan10 - Group 10
  State is Standby
    1 state change, last state change 00:00:01
  Virtual IP address is 10.10.10.1
  Active virtual MAC address is 0000.0c07.ac0a (MAC Not In Use)
    Local virtual MAC address is 0000.0c07.ac0a (v1 default)
  Hello time 3 sec, hold time 10 sec
    Next hello sent in 1.184 secs
  Preemption disabled
  Active router is 10.10.10.3, priority 100 (expires in 10.336 sec)
  Standby router is local
  Priority 100 (default 100)
  Group name is "hsrp-Vl10-10" (default)
Switch1(config-if)#
*Apr 12 19:41:03.443: %HSRP-5-STATECHANGE: Vlan10 Grp 10 state Speak -> Standby
Switch1(config-if)#

looks like it's still bugged to the point of the HSRP virtual IP not responding to pings, however not that big of a deal as you can verify HSRP is still setup correctly since the hello's are still being sent and you can cycle the active/standby gateways

there's a later Nov 2013 image as well. At first it looks like HSRP isn't working. However disabling IGMP snooping corrects the issue. still no pings to the virtual ip however.

Dragging up an elderish post but there seems to be yah and no on this one?

I've done a simple two switch config with multiple VLANs and multiple L3 interfaces for each VLAN.

For simplicity I shutdown all the interfaces bar one on each switch.

Switch A
VLAN1
IP 1.1.1.11
HSRP 1.1.1.1
Priority 105
Switch B
VLAN1
IP 1.1.1.12
HSRP 1.1.1.1
Priority 100

Switch A can ping 1.1.1.11
Switch A can ping 1.1.1.12
Switch A can ping 1.1.1.1 (when Active)
Switch B can ping 1.1.1.11
Switch B can ping 1.1.1.12
Switch B CANNOT ping 1.1.1.1 (when secondary)

Bring Switch B on as Active (change priority to 110)

Switch B can ping 1.1.1.11
Switch B can ping 1.1.1.12
Switch B can ping 1.1.1.1 (when Active)
Switch A can ping 1.1.1.11
Switch A can ping 1.1.1.12
Switch A CANNOT ping 1.1.1.1 (when secondary)

This to me is NOT normal HSRP behavior no matter what way you cut it, both Switches should be able to ping the VIP regardless of status in the HSRP group.

The IOU I'm using does not support VACL. Can anyone help with a relevant IOU
