I have multiple LNS (CCR) devices around the country which I use to provide full HA to our IPIP Tunnel customers.
VRRP is used between sites to allow for a single IPIP Tunnel termination configuration
BGP is used to replicate the active routes to the various VRF's
The issue is that if one creates an IPIP interface on a standby device, it is marked as Running, even though the CPE has not connected to it. This presents a problem when routes are added to the device (LNS) as BGP will in turn replicates them. This would cause routing issues on the network as all routes will be seen as active, but pointing to devices with no customers. (No failure of any devices).
Is there a way to stop the interface from being active until the CPE connects and establishes the IPIP Tunnel, or at least the routes need to remain inactive until the IPIP tunnel is actually up.
