Prerequisites for
MPLS VPN Support for EIGRP Between PE
and CE
This document assumes that BGP is configured in the network core. You will also need to complete the
following tasks before you can configure this feature:
following tasks before you can configure this feature:
•
MPLS and Cisco Express Forwarding (CEF) must be configured in the BGP core network. EIGRP
and multiprotocol BGP (mBGP) must be configured on all PE routers that provide VPN services to
the CE routers at the customer sites.
and multiprotocol BGP (mBGP) must be configured on all PE routers that provide VPN services to
the CE routers at the customer sites.
•
The metric must be configured for routes from external EIGRP autonomous systems and non-EIGRP
networks before these routes can be redistributed into an EIGRP CE router. The metric can be
configured in the redistribute statement using the redistribute (IP) command or configured with the
default-metric (EIGRP) command.

Metric Must Be Configured for Routes from Other Autonomous Systems and Non-EIGRP Networks
If an external route is received from another EIGRP autonomous system or a non-EIGRP network
without a configured metric, the route will not be advertised to the CE router. The metric can be
configured in the redistribute statement using the redistribute command or configured with the
default-metric command.
without a configured metric, the route will not be advertised to the CE router. The metric can be
configured in the redistribute statement using the redistribute command or configured with the
default-metric command.
Native EIGRP VRF to VRF Redistribution is Not Supported
Redistribution between native EIGRP VRFs is not supported. This is designed behavior.
