NOTE:
After you configure a VPN site as an iBGP peer of the MCE, the MCE does not advertise the BGP routes
learned from the VPN site to other iBGP peers, including VPNv4 peers. Only when you configure the VPN
site as a client of the RR (the MCE), does the MCE advertise routes learned from it to other iBGP peers.

A VPN site must advertise the VPN
network addresses it can reach to
the connected MCE.
Configuring routing between MCE and PE
MCE-PE routing configuration includes these tasks:
•
Bind the MCE-PE interfaces to VPN instances
•
Perform route configurations
•
Redistribute VPN routes into the routing protocol running between the MCE and the PE.
NOTE:
Configurations in this section are configured on the MCE. Configurations on the PE are similar to those on
the PE in common MPLS L3VPN network solutions (see “
Configuring routing between PE and CE
”).
Configuring static routing between MCE and PE
