Configuring an OSPFv3 Distribution List using a Route Map as input

A route map that matches internal routes can be used to filter OSPFv3 routes.

Enter the show ipv6 ospf route command to verify the OSPFv3 routes.

device# show ipv6 ospf route
  Current Route count: 5
    Intra: 3 Inter: 0 External: 2 (Type1 0/Type2 2)
    Equal-cost multi-path: 0
    Destination                    Options   Area             Cost Type2 Cost

*IA 2001:db8:4::/64                --------- 0.0.0.0            10 0
    ::                             ve 11
*E2 2001:db8:5::/64                --------- 0.0.0.0            10 0

Enter the enable command to access privileged EXEC mode.
```
device> enable
```

Enter the configure terminal command to access global configuration mode.
```
device# configure terminal
```

Enter the ip router-id command to specify the router ID.
```
device(config)# ip router-id 10.11.12.13
```

Enter the route-map command, using the permit keyword and specify a name.
```
device(config)# route-map allowInternalRoutes permit 10
```
A route map called “allowInternalRoutes” that permits a matching pattern is configured.

Enter the match route-type command, using the internal keyword to match internal route types in the route map instance.
```
device(config-routemap allowInternalRoutes)# match route-type internal
```

Enter the exit command to return to global configuration mode.
```
device(config-routemap allowInternalRoutes)# exit
```

Enter the ipv6 router ospf command to enter OSPFv3 router configuration mode and enable OSPFv3 on the device.
```
device(config)# ipv6 router ospf
```

Enter the distribute-list route-map command, using the in keyword and specifying a name to create a distribution list a distribution list using the configured route map “allowInternalRoutes”.
```
device(config-ospf6-router)# distribute-list route-map allowInternalRoutes in
```

Enter the exit command until you return to user EXEC mode.
```
device(config-ospf6-router)# exit
```

Enter the show ipv6 ospf route command to verify that the external routes are omitted from the OSPFv3 route table.

device> show ipv6 ospf route
  Current Route count: 3
    Intra: 3 Inter: 0 External: 0 (Type1 0/Type2 0)
    Equal-cost multi-path: 0

    ::                             ve 10
*IA 2001:db8:3015::/64             V6E---R-- 0.0.0.0            11 0
    fe80::2e0:52ff:fe00:10         ve 10
*IA 2001:db8:3020::/64             --------- 0.0.0.0            10 0
    ::                             ve 11

The following example configures a route map that is used to filter OSPFv3 routes. A distribution list is then configured and external routes omitted from the OSPFv3 route table.

device> show ipv6 ospf route
device> enable
device# configure terminal
device(config)# ip router-id 10.11.12.13
device(config)# route-map allowInternalRoutes permit 10
device(config-routemap allowInternalRoutes)# match route-type internal
device(config-routemap allowInternalRoutes)# exit
device(config)# ipv6 router ospf
device(config-ospf6-router)# distribute-list route-map allowinternalroutes in
device(config-ospf6-router)# exit
device> show ipv6 ospf route
