The routers on a stick are running VRRP on g0/0.10, g0/0.20 and g0/0.30.
On switches, ports fa0/1-8 are on VLAN 10, fa0/23 and fa0/24 are configured as trunk port, with allowed VLANs 10, 20 and 30.

Show VRRP on HQ2 shows that all VRRP are as master, but on HQ1, they show as init, router are 2900 running IOS 15.1 and switch are 3560 running IOS 12.2,
I had the router on a stick running on 1 router and 1 switch with no problem and also VRRP running on a single switch with no problem, but there is something I do not understand here! there is no other config on router and switches.
address on HQ2 have been change to x.x.x.253. config HQ1

Configuration on the other router is the same except that address for g0/0.10 .20 and .30 terminate with 253 instead of 254 and of course the address for the serial connection is different. also discover a bad port on the switch so both VRRP are saying master now, so they do not communicate.

  • How do you have the routers with the same addresses? Each router needs its own address. You should also edit your question to include the router configurations.

  • It appears you have some misconfiguration on the switches. If the VRRP routers can't communicate on the LAN, each will think it's the master. You should make sure that you set the VRRP priorities and the STP priorities so that layer-2 and layer-3 traffic will flow the same direction. The router with the high VRRP priority should connect to the switch with the low STP priority.

  • @Ron Maupin I found a bad port on f0/24 on one switch, that is why it was staying at init. just to be sure f0/23 and f0/24 should be set as trunk right ? I will only be able to continue tomorrow as the place is closed

Reset to default

OK, I found the problem, for some reason erasing the startup-config did not really erased everything, So I went in rommon and reset HQ2 to factory default and it is working.

  • After you erase a startup configuration, you must reload the device before configuring it. Also, that doesn't erase the VLAN database on a switch.

  • @RonMaupin reload was done, but VLAN info was not erase, I will try that to solve my last weird problem

  • You can go into VLAN database mode from the enable prompt, and you can fix the VLAN database.

  • @RonMaupin Since I have the startup config in notepad++, I deleted the startup and vlan.dat and I am reloading both of my switch right now
