# sk175887 - VTI Routes are not added correctly when more than 50 VTI Tunnels are used

| Products | Security Gateway |

| OS | Gaia |

## Symptoms

- * Any created static route pointing out the vpnt interface (or the nexthop peer) do not show in the routing table.

* When installing policy, a cluster VIP from another VTI can be assigned to newly created VTI.

* Log in /var/log/routed_messages shows that the VIP is added somewhere else. For example, IP for vpnt67 is removed so it can become vpnt84's IP:  

  `
  [DATE TIME] cpcl_create_address(3319): Removing X.X.X.X from vpnt67 so it can become vpnt84's cluster IP`

## Cause

When using more than 50 VPN Tunnel Interfaces (VTI), the temporary storage runs out, and the Security Gateway start assigning VIP's used by other interfaces to a new VTI.
