1. AnchorWLC - WLC4402 anchor in a DMZ for guest access
2. WLCA1 - WLC4402 on SiteA
3. WLCB1 - WLC2006 on SiteB
4. WLCB2 - WLC2006 on SiteB
SiteA & SiteB are geographically separated.
On all WLC's there is the same mobility group 'group1' with the following group members:
1.on AnchorWLC: group1 members:WLCA1,WLCB1,WLCB2
2.on WLCA1: group1 members: anchorWLC
3.on WLCB1: group1 members: WLCB2,anchorWLC
4.on WLCB2: group1 members:WLCB1,anchorWLC
As SiteA and SiteB are geographically separated I have not included internal(non-anchor) WLC's that are on siteA in the mobility group created on WLC's on SiteB and vice versa . The only WLC that has all controllers added to his mobility group is the AnchorWLC as guest access is needed from both siteA and siteB.
Is this a valid config(anayway it is working...) or is it recommended to have 2 different mobility groups, one for each site(A & B) and create 2 seperate mobility groups on the anchorWLC ?
