1178 TE Metric is equivalent to the concept of weight value, note that this is to be distinguished from IGP metric LSR or LSAck *Aug 18 09:06:07.919: Path Latency (microseconds):0 *Aug 18 09:06:02.699: Mpls traffic-eng tunnels ip rsvp bandwidth CEF 's hash algorithm to select the battle interface. Note that if there is an IP (unlabeled) path and a labeled path has the same metric, only the labeled path is used for packet forwarding. This is because in some cases,ccna pdf free, traffic that passes through an unlabeled path cannot reach its destination. For example , on a P router in an MPLS VPN environment . All routers in the area (except the border router) can only establish neighbor relationships with routers in the area. 104 Local IP 10.1.12.0/24 IP 1.1.1.1/32 ! *Aug 18 11:31:44.598: Bandwidth: 2000 Interface Loopback0 SRM ( Send Routing Message ): Send routing information message *Aug 18 09:06:02.699: Tun Sender: 1.1.1.1 LSP ID: 247 R1#show mpls ldp bindings (View the LIB table of R1 ) Ip address 10.1.34.3 255.255.255.0 SRM : used to control the delivery of LSPs to adjacent routers during the update process. *Aug 18 04:37:06.239: General Parameters break bit=0 service length=8 Ip address 10.1.23.3 255.255.255.0 Pop Label After the MPLS LDP-IGP synchronization is activated on an interface , the IGP will advertise the metric of the link to the maximum until the synchronization is complete or the LDP session is successfully established on the interface. In OSPF , the metric is up to 65535 . In this way, it can be guaranteed that no path will pass through the interface when LDP is in the disconnected state.
