48.1.1.1 Establishing Routes with CE
The Multi-VRF CE switch can establish routes with CE through multiple dynamic routing protocols. CE can be
routers or the Ethernet switches. The routing protocols which are supported include OSPF, RIP and BEIGRP.
The MCE switch also supports static routing configuration.
The MCE switch generally needs different VLAN ports to connect CEs that belong to different VPNs. The
VLAN ports that are used to connect the VPNs require to be related to a VRF. CE does not need to support
VRF.
48.1.1.2 Establishing Routes with PE
The MCE switch (MCE) can connect one or multiple PEs, but both MCE and the connected PEs have to get
VRF configured. MCE will provide PE the routes which MCE learns from CE and learns the routes of remote
client networks from PE.
The VRF route can be established between MCE and PE through dynamic routing protocols such as BGP,
OSPF, RIP and BEIGRP. Of course, the VRF route can also be established statically.
In general, MCE and PE belong to different autonomous systems. Hence, the method to establish the VRF
route between MCE and PE by using EBGP is the key point in this document.
