Hi,
the config looks nearly good.
You just defined the nodes with the commands
sccp ccm 10.10.20.11 identifier 1 version 7.0
sccp ccm 10.10.20.10 identifier 2 version 7.0
sccp ccm 10.11.20.10 identifier 3 version 7.0
sccp ccm 10.12.20.10 identifier 4 version 7.0
But you also have to assign it to the SCCP group. You only added one.
Should look like:
sccp ccm group 1
bind interface BVI1
associate ccm 1 priority 1
associate ccm 2 priority 2
associate ccm 3 priority 3
associate ccm 4 priority 4
=> The number here refers to the identifier in the command sccp ccm <IP> identifier <id> version 7.0
Assign priority to the ccm's, which fits best to your setup
For the command ccm-manager config server <IP>, to specify multiple IP's, you have to do it like this:
ccm-manager config server <IP> <IP> ...
IP's are separated with a space
I don't know, how many IP's you can assign there. But 2 or 3 should be enough, because these IP's only represent the TFTP-servers, from where the VG gets it's config, if you make any changes in the CUCM.
And since it's only in case of config changes (normally in the daily operation happening rarely), the VG doesn't always contact these IP's.
