PE-CE Routing Protocol-OSPF and EIGRP
Chapter 4, "PE-CE Routing Protocol – Static and RIP," provided you with an overview and steps to configure static and RIP PE-CE routing protocol in an MPLS VPN environment.
This chapter introduces you to OSPF and EIGRP PE-CE routing protocol concepts and includes the following:
- OSPF PE-CE routing protocol overview, configuration and verification
- Traditional OSPF routing model
- MPLS VPN or OSPF superbackbone concept
- OSPF route-propagation using the MPLS VPN superbackbone
- OSPF down bit and domain tag
- Configuring and verification of OSPF PE-CE routing
- OSPF sham-links
- EIGRP PE-CE routing protocol overview, configuration, and verification
- EIGRP route propagation
- Configuration flowchart for EIGRP PE-CE routing
- Routing loops and suboptimal routing
- BGP cost community feature
- EIGRP site of origin (SoO) attribute
