Trying to get BVI working on a pair of Cisco NCS 5500 running version 7.0.1 but cannot ping the other end. There is a single link between the routers in a bundle. I can ping the far-end router using the directly-assigned IP on the BE, but cannot ping...
Nessus scans shows that my switches are performing IP forwarding. Switches are IOS (4948E) and NXOS (9300). All of them are using the management or mgmtVRF VRFs for their management connections, and it's this IP that is forwarding. If I point one swi...
Is VXLAN supported on the Nexus 5500 series? I am seeing conflicting information on the web, but cannot see any details in any of the configuration guides, or VXLAN listed on the data sheet for that series. There is a mention of VXLAN in the latest r...

No I never found a way, but I never looked after my initial post. I filed a report with security explaining why it ultimately was not a security concern for us.
All management interfaces for our network devices are using dedicated VRFs which connect ...
I have a 4900M with the same problem except I am running 15.2(1)E. The latest config guide I can find for the 15 train is 15.0 which does not list DNS as being supported for VRF. However, there are some commands that make it appear it is.
