Configuration Example. MPLS: Layer 3 VPNs Configuration Guide, Cisco IOS XE Release 3S . MPLS: Layer 3 VPNs Configuration Guide, Cisco IOS Release 15M&T . VRF (Virtual Routing and Forwarding) is a technology which allows to have more than one routing table on a single router. Here is the VRF configuration from PE1 and PE2: PE1#show running-config That sounds correct, I noticed the same behavior in my MPLS VPN export map example. Each CE router has two loopback interfaces. show ip pim vrf <vrf-name> mdt receive—Displays the data MDT advertisements received by the router in the specified VRF. Example: Configuring MPLS VPN Half-Duplex VRF Using Dynamic CE-PE Routing. The PE router creates one VRF table for each VPN that has a connection to a CE router. This section provides the following configuration examples: • Enabling MPLS VPNs • Creating a VRF Routing Table • Defining VRF Selection Entries • Defining IP Static Routes for a VRF Configuration example on nPE1: enable configure terminal spanning-tree pseudo-information transmit 46 remote-id 53 mst 0 root 32768 0000. Configure VRF under the interface: Router#configure Router(config-subif)#interface TenGigE0/0/0/0. The following example shows how to use Open Shortest Path First (OSPF) to dynamically advertise the routes on the spoke sites. Enable MPLS encapsulation on the required interface. This example uses the hub-and-spoke topology shown in the figure below with local authentication (that is, the RADIUS server is not used): Figure 2. 2222 vlan 1001 evi auto vrf context Tenant-A evi 30001 interface loopback 1 ip address 192.
