MPLS does not assign labels to BGP routes,ccna exam code 2015, but assigns labels to the next hop of BGP routes. SNP serial number packet Router ospf 1 Bw[0]: An IP address. Local label info: global/16 Let's look at an example: Interface eth0/0 R1#show mpls traffic-eng tunnels R1.00-00 R1 # show mpls forwarding-table R1 of LFIB table Fa0/0 Hostname: R1 IP Address: Metric: 10 Link State ID: 1.0.0.0 Opaque Type: 1 Priority 7 : 9375000 *Aug 18 09:06:07.919: SESSION type 7 length 16: All routers in the area (except the border router) can only establish neighbor relationships with routers in the area. Label or VC Config Parameters: RSVP extension to LSP tunnel Then, finally, the data is introduced into the established tunnel . In fact, after creating a TE tunnel on R1 , a local tunnel is in it. Interface tunnel0 Ip ospf cost 1 Next, R1 calculates another alternative path to R7 through the existing information : R1-R2-R4-R5-R7 , this path passes CSPF The first label is applied on the ingress LSR and the label belongs to one LSP. The path of the packet through the MPLS network is bound to that one LSP. All that changes is that the top label in the label stack is swapped at each hop The ingress LSR imposes one or more labels on the packet. The intermediate LSRs swap the top label (the incoming label) of the received labeled packet with another label (the outgoing label) and the transmit the packet on the outgoing link. The egress LSR Of the LSP strips off the labels of this LSP and forwards the packet.
