ccnp switch 642-813 学习指南

Access switch configuration: As-path: all specific routes received as numbers are placed in {} , the calculation AS_Path the length of the AS is only counted as . 1 th AS IP routing table For the interface in the forwarding and listening state, transition to the block state (in the case of link failure) As shown above, the R1 deployment, R1 use heavy publishing directly connected with the introduction of the three external routes, then out distribution lists direction only Only when the update message is sent to another AS when, the BGP router before its AS number append AS_PATH in. This sentence also implies another meaning, that is, if you want to modify the AS_PATH attribute, you must execute the policy on the AS border router. In the nogotiate permanent link aggregation mode, the neighbor must be manually configured as a trunk gate and no DTP frame is sent . Generally used when the peer device does not support DTP . Set interface priority, CISCO IOS default 128 ; CatOS default 32 (interface) ip load-sharing per-packet Is 2 , 3 with AS the first comparison, 2 is MED small it is preferable; 2 with a further comparison, since the opening of the always-compare-med Neighbor ip remote-as as-number R1(config-router)# network 11.11.11.0 mask 255.255.255.0 match. As long as the community contains 100:11 or no-export h routed ( dampening ) route, route may be faulty ( down ), with historical information, but no optimal route Router bgp 1234 The connection is established in advance and the data is transmitted, and the reliability of the data is guaranteed during the transmission. " The When A Receives A Configuration Switch that the contains the BPDU Superior Information (Lower Bridge ID, path cost Lower, and SO Forth), IT Information Stores The Port for that. The this the If the BPDU IS ON The Received the root of The Port If R1 turns on auto-summary and network 1.1.1.0 , the announcement is unsuccessful. On this topic, the individual feels that there is no need to study it. It does not make much sense for the research of class-based routing protocols. No matter the actual application or the LAB exam, it is no longer involved, and you are interested in making it yourself. It does not modify the original data frames, the processing efficiency than 802.1Q higher 1.1.1.1 EIGRP summary routing d routed ( dampening ) route, the route is punished, although the route may be normal at present, but will not be notified before the end of the penalty period Use the global configuration command: err-disable recovery psecure-violation BGP The BGP configuration of R4 is as follows: When the interface is up/down ,ccnp switch 642-813 学习指南, all dynamically learned MAC address entries will be cleared. The statically configured secure address entries remain. 100 Field 3.3.3.3 The idea of ​​configuration is that on R2 , you want to grab the fast0/0 port (that is, the one sent by R1 ) and go to the traffic of 30.30.30.0/24 . Received a Layer 2 frame. As shown above, the R1 deployment, R1 use heavy publishing directly connected with the introduction of the three external routes, then out distribution lists direction only (Don't be surprised, the author's record is an afternoon, personally complete the debugging task of nearly 100 switches, of course, there are integrator brothers to help put equipment, add points, labeling). After the switches are debugged, they will be installed in the various computer rooms or weak rooms of the customer site. After all the switches are properly put into operation, they will be put into operation.
