In addition,ccna training classes, it also supports IS-IS based MPLS TE 0x00000014 Fast tag rewrite with Fa0/0, 10.1.12.2, tags commit: {203} via 10.1.12.2, FastEthernet0/0, 0 dependencies Attribute Flags: 0x00000000 OAM alarm tag Choose the path with the largest " minimum available bandwidth " Network 10.1.34.3 0.0.0.0 area 0 mpls traffic-eng router-id loopback0 mpls traffic-eng area 0 1bit Addresses bound to peer LDP Ident: Let's take a look, why is it exposed to network information? Suppose A below router E , E made to be a packet to D under F. , The data packet is A tag the transferred B , assumed that the BC loop appears between subsequent label TTL is decremented to 0 , since the TTL value The setting is very small, so very quickly, the TTL is decremented to 0. At this time, B (message discarder) will send an ICMP error message back to E. Then, if B has E route (or label), B will The ICMP error message will be sent directly back to E. If not, B will continue to tag the error message and gradually pass it to D , D.As the PE , about E route, then back to the label and then loaded on E . Then, no matter what the situation, the final E can receive the ICMP error message generated by B.
