Configuring an OSPFv2 Sham Link
This task explains how to configure a provider edge (PE) router to establish an OSPFv2 sham link connection
across a VPN backbone. This task is optional.
Before You Begin
Before configuring a sham link in a Multiprotocol Label Switching (MPLS) VPN between
provider edge (PE) routers, OSPF must be enabled as follows:
•
Create an OSPF routing process.
•
Configure a loopback interface that belongs to VRF and assign a IPv4 address with the host mask to it.
•
Configure the sham link under the area submode.
See Enabling OSPF, on page 358 for information on these OSPF configuration prerequisites.
