Subject Re: CS Mgmt Server can't connect to virtual router by management network
Date Sat, 14 Sep 2013 07:45:13 GMT
Is this a new or existing installation?  If there are existing
functional virtual routers, how does the routing table compare to the
broken one?  Does the broken virtual router at least have a management
IP in the correct range (the range configured for the pod)?  Did you try
a stop/start of the virtual router, or destroy/recreate it?

System VMs on shared networks will use the guest network as the default
gateway, but IIRC they will also be configured with a static route on
the management network to the network of the management server.  Is the
"host" parameter in Global Settings correctly configured to the IP of
the management server or a load balancer for a cluster of management

Best regards,

problem is that there is no gateway be set for VLAN B in vRouter,  there is only a default
gateway for VLAN A, So the VLAN B ip address can't be reached from VLAN C and any other VLANs.

your gateway make sure that you have a route to reach from Vlan B to Vlan C
