Tun Sender: 1.1.1.1, LSP ID: 521 Ip unnumbered Loopback0 tunnel mode mpls traffic-eng tunnel destination 4.4.4.4 By default, CISCO IOS does not trigger re-optimization when a link in the network can be reused by a TE tunnel , but can activate this operation. To enable re-optimization when a link becomes operational in MPLS TE , use the following command: Ip address 3.3.3.3 255.255.255.255 4 10.1.45.5 8 msec 8 msec * 0 (only media is shared) Ip router isis Ip cef Is a sequence of LSRs that switch a labeled packet through an MPLS network or part of an MPLS network. RESV The LSR route may receive multiple labels of a specific prefix ( distributed by multiple LDP neighbors),take ccna test, but he only needs to use one of them. The IP routing table is used to determine the next hop of the IPv4 prefix ( the construction of the LFIB needs one). IGP routing table, because the next hop of LFIB is calculated from the IGP table). The LSR uses this information to create its LFIB . The label bundled locally in the LFIB is used as an inbound label, and the label advertised by the LDP neighbor is used as an outbound label.
