Output Queue[0]: 0<br />

The first two lines of the output show the peer’s IP address, which is RouterF’s<br />

address, and that the IBGP session is established. The Address families configured<br />

line shows that this interface can process VPN-IPv4 addresses (inet-vpn-unicast).<br />

Further down in the output, you see information about the bgp.l3vpn.0 routing<br />

table.<br />

The VPN traffic between the two sites will be carried over an MPLS LSP. In the second<br />

part of the configuration, create this LSP on the two PE routers with the set<br />

label-switched-path commands. Use the show mpls lsp command to verify that the<br />

LSP is functional. Here, we check on RouterG:<br />

The output shows what you expect. RouterG has one ingress LSP session, to<br />

RouterF, and one egress session, from RouterF.<br />

At this point, you are ready to set up the VPN itself. Each VPN requires its own routing<br />

instance so that all information related to one VPN and its routing can be isolated<br />

from other routing and forwarding and from other VPNs that the router is<br />

managing. The set instance-type vrf command indicates the routing instance as<br />

being for a VPN and that its routes will be placed in the VRF routing table.<br />
