OAW 4604 Master-Master Redundancy

[alf]

Hello,

i have two OAW 4604 in VRRP Master-Master Redundancy.

OAW 1:
VLAN 1 IP 10.0.0.102 (Loopback 10.0.0.104)
VRRP ID 5 Prio 110

OAW 2:
VLAN 1 IP 10.0.0.103 (Loopback 10.0.0.105)
VRRP ID 5 Prio 100

VRRP IP 10.0.0.101

Redundancy function works, but if i connect wireless (AP125) to the network and ping the gateway 10.0.0.1, i habe some timeouts in case of redundance takeover.

is this right?
is a time out in vrrp ok?

[cedric1]

yes you have a timeout, time of 'backup keepalive'

if backup don't get x times no vrrp advertise he conclude to become master

so if you have timemout is normal

yet it depneds how many

you can improve this in vrrp timer so backup will be mastet faster

okay,

it works but sometimes my vrrp ip 10.10.0.101 is on wlan mgr 10.10.0.102, some seconds later i'm logged out and login screen on 10.10.0.103 (second wlan mgr).

but the lan connection is working fine! both 4504 are on the same switch, no vlan programmed...

[alf]

any ideas?

i cant find anything in the logfiles...

[alf]

ok, i think it was the different clock setting ons both oaw.

i think, not i know... currently it works.

hello

strange that time can influcence vrrp

Let us know

Sorry for "reopening" this topic.

Since in network you have 2 wireless controllers OAW 4604 are they doing someking of synchronization? From AP's poing of view there is only on controller with IP address 10.0.0.101 (VRRP virtual address).

But what is about controller's view? Do you have to configure user profiles and other settings on both controllers or just on one (and then to give synchornization from one controller to another one)?

I suppose that if redundancy is needed only option is to have 2 controllers in network?

The redundance from AP view is that there is only one master (or local) ip = VRRP virtual address.
You have to configure at the "backup master" only the wired network (with vrrp and vrrp priority) and the ip of the "active master".
All other configs you do at the active master. It will synchronice both databases in case of changes.

This means that 2 wireless controllers work in "active-standby" mode. After secondary controller becomes active it already has valid (synchronized) configuration.
