HELLO holdtime is the maximum allowable interval for an IS-IS router to receive 2 consecutive hello packets. Hello holdtime=hello interval × hello multiplier . Therefore hello holdtime defaults to 30S . If a router has not received any hello after the hello holdtime expires , the neighbor is declared invalid. Bw-based ! Run OSPF on the entire network to announce direct connection and loopback interface. *Aug 18 09:06:02.699: SENDER_TSPEC type 2 length 36: Define source A copy of the LSP to initiate a cleanup process. This method effectively ensures that other routers in the network clear the corrupted LSP . The corrupted LSP does not participate in the route calculation, and of course it will not be flooded in the network. !! Pay close attention to here 204 0 kbits/sec Then show it: There are four metric types: UP 28 10.1.35.55 -> 1.1.1.1 : FastEthernet0/0 (next hop 10.1.23.2) Bytes tag R1#show isis neighbors Interface eth 0/0 0 interfaces: Fa0/0 Reservable Bandwidth[7]: Domain-wide Prefix Distribution with Two-Level IS-IS Find a LFIB , LFIB has the next hop information, so the top label is popped up and then handed over to the next hop without having to look up the FIB table again (if the label is popped, it is an IP packet). From which interface a tag packet is received, as long as it has this tag, it will be exchanged. Adding the force keyword will take effect immediately. Otherwise, only when the interface selected as the routeriD is DOWN , the reselection will be performed. Note: The router ID of the LDP neighbor must have reachable routes locally. Restrictions: Router isis !! Don't forget the mapping of CLNS Interface Serial0/1 Match ip address prefix-list test router isis Interface Tunnel0 RFC 2370 describes an extension of OSPF that defines three new LSAs . These LSAs are called sluggish LSAs ( opaque LSAs ) and their differences are limited to the extent of propagation. These LSAs can accurately provide the information required by MPLS TE to OSPF : IS-IS supports ISO connectionless network environment, pay attention to the data link is This TLV , in this way, provides a simple and reliable mechanism for advertising hostname information. As shown in the figure below, this is an LSP message: Or Tunnel Id Labels: 200 RECORD_ROUTE *Aug 18 11:31:44.598: Router-id 4.4.4.4 Router(config-if)# mpls traffic-eng path-option x {dynamic | explicit name y } [ lockdown ] Ip router isis router isis R3.00-00 BGP route delivery in MPLS environment Router-id 3.3.3.3 !

For example , the ISO CLNP workstation searched by the ES-IS protocol . The above label, there is another way to see, is to look at the TE Tunnel directly on R2 : AutoRoute only affects the head end of the TE tunnel. Other routers do not know the existence of the TE tunnel and will not affect their routing. My Address: 10.1.23.2 *Aug 18 09:06:02.699: Controlled Load Service break bit=0 service length=0 Since the IP packet destined for 6.6.6.6 is sent to R2 , the IP packet is pushed into the VPN label 505 under the inner layer , which is no problem. Then we continue, the VPNv4 route on 6.6.6.6 on R2 is passed by 5.5.5.5, which is R5 .

If level2 is not specified , the default level1 authentication. If the interface is enabled for plain text authentication, the password is inserted into all IS-IS packets: IIH , LSP , CSNP , and PSNP (based on a specific level ). When actually capturing packets on the CISCO device, it is found that only the password information of the plaintext is carried in the IIH (placed for authentication).
