Intermediate System Intermediate System The configuration of R4 is as follows: Ip address 10.1.34.4 255.255.255.0 The loopback0 address space of all devices is xxxx/32 , and x is the device number. Ip address 55.55.55.55 255.255.255.255 IS-IS can ignore TLVs it does not support This state has three values: down , init , up The label mapping message that is advertised locally is meaningful to the global . The labels corresponding to the same FEC advertised from different interfaces are the same. Is-type level-2-only 204 i ia 10.1.24.0 [115/148] via 10.1.123.2, FastEthernet0/0 i ia 10.1.45.0 [115/158] via 10.1.123.2, FastEthernet0/0 i ia 10.1.34.0 [115/158] via 10.1.123.2 , FastEthernet0/0 C 10.1.123.0 is directly connected, FastEthernet0/0 i*L1 0.0.0.0/0 [115/10] via 10.1.123.3, FastEthernet0/0 Ability to send detail link information , including bandwidth . Replaces IS Neighbor TLV TLV 22 can contain 7 sub- TLVs ,free ccna quiz, three of which contain bandwidth information for TE Therefore, when R2 sends the label packet to the tunnel , the label that is pushed into the outer layer is 304 , and this 304 is obviously allocated by R3 , and is the label assigned by RSVP to the TE tunnel . L2 router , connected to different Leve1 area . Stores a separate Level2 LSDB . Level1 area default route Tunnel mpls traffic-eng autoroute announce Usually LDP sessions are established between directly connected LSRs , but in some cases, a remote, or destination-based LDP session, such as a TE tunnel in an MPLS VPN , may be required . When a link flapping occurs, a destination-based LDP neighbor can improve the label convergence time relative to the directly connected LDP peer. Because if it is directly connected LDP neighbors, two LSR link between if DOWN out, then LDP session will DOWN , however the purpose of the LDP session, another alternative paths can be used to carry LDP TCP packets , so, even if even if the link DOWN out, LDP session is still valid, all tags will be retained, while the link may soon resume LIB label in the update to LFIB go.
