RC-301
Cisco IOS XR Routing Configuration Guide
To understand virtual links, see the “Virtual Link and Transit Area for OSPF” section on page 233.
In this example, all interfaces on router ABR1 use MD5 authentication:
router ospf ABR1
router-id 10.10.10.10
authentication message-digest
message-digest-key 100 md5 0 cisco
area 0
interface pos 0/2/0/1
interface pos 0/3/0/0
area 1
interface pos 0/3/0/1
virtual-link 10.10.5.5
!
!
In this example, only area 1 interfaces on router ABR3 use MD5 authentication:
router ospf ABR2
router-id 10.10.5.5
area 0
area 1
authentication message-digest
message-digest-key 100 md5 0 cisco
interface pos 0/9/0/1
virtual-link 10.10.10.10
area 3
interface Loopback 0
interface pos 0/9/0/0
!
Where to Go Next
To configure route maps through the RPL for OSPF Version 2, see the Implementing Routing Policy on
Cisco IOS XR Software document.
To build an MPLS TE topology, create tunnels, and configure forwarding over the tunnel for OSPF
Version 2; see the Cisco IOS XR MPLS Configuration Guide.
