MPLS TE in MPLS L3VPN
Configuration Example
7 Create a static route for routing MPLS TE tunnel traffic
[RouterA] ip route-static 4.4.4.4 32 tunnel 4 preference 1
Perform the display ip routing-table command on Router A. You can find a
static route entry with Tunnel3 as the outgoing interface.
Network requirements
CE 1 and CE 2 belong to VPN 1. They are connected to the MPLS backbone
respectively through PE 1 and PE 2. The IGP protocol running on the MPLS
backbone is OSPF.
Do the following:
Set up an MPLS TE tunnel to forward the VPN traffic from PE 1 to PE 2.
■
To allow the MPLS L3VPN traffic to travel the TE tunnel, configure a tunneling
■
policy to use a CR-LSP as the VPN tunnel when creating the VPN.
