After configuring MPLS and LDP, if you look in the default JUNOS routing table,<br />

inet.0, you don’t see any of the MPLS or LSP routes and you don’t see any routers<br />

learned from LDP:<br />

aviva@RouterG> show route table inet.0<br />

inet.0: 12 destinations, 13 routes (12 active, 0 holddown, 0 hidden)<br />

+ = Active Route, - = Last Active, * = Both<br />

MultiRecv<br />

This routing table shows only the unicast routes, listing the routes learned from<br />

OSPF, which is the IGP we configured in the previous recipe, and the directly connected<br />

routes. In the JUNOS software, MPLS and LDP store their routing and forwarding<br />

information in two other routing tables, inet.3 and mpls.0. The inet.3 table<br />

contains the LDP FECs:<br />

aviva@RouterG> show route table inet.3<br />

inet.3: 2 destinations, 2 routes (2 active, 0 holddown, 0 hidden)<br />

+ = Active Route, - = Last Active, * = Both<br />
