Using Data Domain for multiple Avamar in different network

Hi,

We have a Data Domain integrated with Avamar and everything is working ok.

Now, we need to use this Data Domain for a different Avamar as well which is in a seperate network. So, basically we want to use DD as shared storage.

We have configured 2 interfaces on the Data Domain having IPs in the same range as that of new Avamar.

New Avamar :

Backup IP - 10.35.76.10

Management IP - 10.207.132.29

New interfaces on DD :

eth3a.1720 - 10.35.74.11

eth3b.1720 - 10.35.74.12

When I try to integrate DD with new Avamar, I get an error message : The Data Domain system is unreachable

I am able to ping the DD IP 10.35.74.11/10.35.74.12 from Avamar

Can someone please help me with ideas.

Thanks.
