# sk184235 - OSPFv2 route redistribution between instances does not work on Security Gateway

## Symptoms

- * On a Security Gateway with two OSPF instances, OSPF routes from instance 1 do not appear in the routing table of the default OSPF instance.

* Attempts to redistribute routes between instances by using routemaps and `set route-redistribution` do not populate the expected routes. For example:  
  `
  Hostname> set route-redistribution to ospf2 instance default from ospf2 instance 1 all-ipv4-routes on`  
  `
  Hostname> restart ospf instance 1`

## Cause

The routemap that controls redistribution between OSPF instances on the Security Gateway is incomplete.

* The routemap on the default OSPF instance only matches and exports external OSPF routes (ospf2ase) that come from instance 1.
* Internal OSPF routes (ospf2) from instance 1 do not match this routemap and are therefore not exported to the default instance.

As a result, only external routes (if any) are redistributed. Internal routes remain local to instance 1, which leads to missing routes and connectivity problems. This behavior is consistent with the way OSPFv2 multiple instances treat redistributed routes as external routes in the receiving instance.
