VPN instances without MPLS?

[paulgear]

Hi everyone,

In my 5500-EI IRF stack, i'd like to have a few different routing instances - potentially one for upstream BGP, one for the management networks, and one for the main data centre networks.  Is this possible using the VPN instances available on Comware 5?

Everything i've found in the documentation suggests that it assumes/requires MPLS transports all through your network, which i don't want - i just want separate instances within the one stack.

Yeah you could use vpn-instances for that, it does not require MPLS.

Thanks Fredrik,

So which parts of the configuration are required in order to set up the VPN instances?  The manuals seem to imply that you must have BGP route descriptors and MPLS.

Just poked through this: http://h20195.www2.hp.com/v2/GetPDF.aspx/4AA3-7311ENW.pdf dont know if thats the one you've been looking at. But you just need to define the vpn-instances, and give them a route-destinguisher. No MPLS _needed_, allthough vpn-instances is used heavily together with MPLS.

So something like this:

#
ip vpn-instance red
 description Customer red
 route-distinguisher 1:1
#
interface GigabitEthernet2/0/1
 description Int to cust red
 ip binding vpn-instance red

 Btw, you can have up to 64 instances on the A5500-EI, up to 1024 on A5500-HI and A5800
