## Symptoms

- * VPN MEP Security Gateways redistribute the RIM routes into OSPF.

* The OSPF database on these VPN MEP Security Gateways contains duplicate entries for the same RIM route that comes from both MEP Security Gateways.

  *Example*:

  ```
  
  HostName> show ospf database
  Link ID           ADV Router           Age    Seq Num      Checksum   Tag
  192.168.160.12    192.168.8.2          1416   0x8000007e    0x614f    0x00000000
  192.168.160.12    192.168.1.2          1409   0x80000488    0x3d3a    0x00000000
  ```

* Changing the primary MEP Security Gateway for the VPN peer and installing the security policy resolves the issue.

## Cause
