Can anyone advise me on setting up a management network for a small campus network with VSP 7200’s as the core, ERS 5900’s (base license) as BEB’s and EXOS switches at the edge. In this deployment there are no BCB’s so I am not worried about avoiding IP on the core. I have been scrubbing through the docs, but I am not finding much to address management across various switches. On the ERS’s I have a C-VLAN set as the management vlan, that gives me management access for the ERS’s and the EXOS switches across the fabric, but I can’t seem to figure out how to get management access to the VSP’s from this management vlan?
I have played around with IP Shortcuts, and can ping the CLIP IP from one VSP to another, but can’t figure out how to reach the CLIP from my management network.

The CLIPs are going to be different IP subnets, so if your mgmt station is in the C-VLAN you will need to give each VSP an IP on that same C-VLAN and have routes to them to reach the CLIPs. Or you can forget about the CLIPs and just manage the VSPs from the IP you give them on that C-VLAN. If this is a small network that is fine.
In large fabrics with many VSPs it is usually preferred to manage the VSPs from the CLIPs (which are advertised via ISIS) rather than stretching a L2 CVLAN across the whole network.
