VRF lite and snmp management

[aalbler]

Hi,

is it possible to poll a router via snmp when the snmp management station is "in" one of the VRFs of the router?

There is a feature called "SNMP support for VPNs" that will allow you to do this. Here's the URL:

Hope this helps,

Sorry for the first answer. I just saw that the mgmt station is IN the VRF. You can obviously poll the router as long as the IP address of that router is part of the VRF. If not, you would have to arrange for that particular address to be imported in the VRF.

Hope this helps,

Hi,

thank you very much for the fast answer.

So the following config would work:

interface fastethernet0/0

ip vrf forwarding vrf.something.at

ip address 10.0.0.1 255.255.255.0

snmp-server community public RO 50

access-list 50 permit 10.0.0.2 0.0.0.0

The snmp management station would be 10.0.0.2

Best Regards & Thanks again

This config will do exactly what you intended to.

Hi Harold,

I have a similar problem, instead I have a Firewall between my router with VRF-Lite running on it and the Firewall is doing the NATting.

I have already posted by problem in detail already.

Any ideas on how to achieve it.

Thanks
