Route Redistribution For Ospfv3: Example - Cisco NCS 6000 Series Configuration Manual

Implementing OSPF

Route Redistribution for OSPFv3: Example

The following example uses prefix lists to limit the routes redistributed from other protocols.
Only routes with 9898:1000 in the upper 32 bits and with prefix lengths from 32 to 64 are redistributed from
BGP 42. Only routes not matching this pattern are redistributed from BGP 1956.
ipv6 prefix-list list1
seq 10 permit 9898:1000::/32 ge 32 le 64
ipv6 prefix-list list2
seq 10 deny 9898:1000::/32 ge 32 le 64
seq 20 permit ::/0 le 128

Virtual Link Configured Through Area 1 for OSPFv3: Example
This example shows how to set up a virtual link to connect the backbone through area 1 for the OSPFv3
topology that consists of areas 0 and 1 and virtual links 10.0.0.217 and 10.0.0.212:
ABR 1 Configuration
router ospfv3 1
router-id 10.0.0.217
area 0
interface GigabitEthernet 0/2/0/1
area 1
virtual-link 10.0.0.212
interface GigabitEthernet 0/2/0/0
ABR 2 Configuration
router ospfv3 1
router-id 10.0.0.212
area 0
interface GigabitEthernet 0/3/0/1
area 1
virtual-link 10.0.0.217
interface GigabitEthernet 0/2/0/0
Virtual Link Configured with MD5 Authentication for OSPF Version 2: Example
The following examples show how to configure a virtual link to your backbone and apply MD5 authentication.
You must perform the steps described on both ABRs at each end of the virtual link.
After you explicitly configure the ABRs, the configuration is inherited by all interfaces bound to that
area—unless you override the values and configure them explicitly for the interface.
