802.1D situation: Destination Address (Route Prefix): This is the destination network number associated with the route entry. A complete route prefix consists of: network number + prefix length R2#show adjacency detail These modes generally only be on high-end Cisco device applications ,ccnp switch short notes, such as 7200 series routers . Or 12,000 Series routers . Command : ip route-cache optimum show ip cache optimum Ip local policy route-map x 0 100 i Set the commu value to append, otherwise override 200 i If there is an EBGP connection between R2 , then a routing loop occurs, and R1 and R2 will receive the summary route and accept the routing update. This is because this summary route does not carry any information about AS100 and AS200 . The distribution list is deployed in a link state routing protocol such as OSPF . If the out direction is to be used, it can only be used in such a situation. About PBR Neighbor 10.1.12.2 remote-as 200 As shown above, the position of the line is 16+4=20 , so we get the summary address: 192.168.0.0/20 , which is the most accurate summary address. [ac 1-2]$ --------------- 192.168.10.1 IBGP neighbor 10 BGP routing table entry for 172.16.0.0/16, version 4 Dialer Dialer interface Switch(config)# vlan 10 When ISP1 is down, the interface of GW connected to ISP1 is DOWN , and the traffic of PC access 100 is automatically switched to ISP2. Port number 521 !! Match the exit of the packet Let's review the 13 routing rules of BGP . In this lab manual, we will verify the main entries in the routing rules and familiarize ourselves with the various properties of BGP . RIP Message Format Before routing 0bits must 0.0.0.0 ago 0 Ge bit match, in fact, all the bits does not matter, but also for the mask, that did not write ge keyword is implicit so ge 0 Le 32 , that is, cover The code length is greater than 0 and less than or equal to 32 . So this prefix list is permit 1 Passive-interface Fa0/0 neighbour xxxxxx ID . CISCO Private Agreement *> 10.1.12.1 from 10.1.12.1 (1.1.1.1) Length of the suboption type Not used (set to all 0s ) trunk permanent link aggregation mode, forced trunk , send DTP frames Port Router ospf 1 Preferred to the nearest route to BGP NEXT_HOP 21 When the GW loses the route to 10.1.12.2 and the connection to ISP2 is also lost, then the default route is taken. RIP Version 2 Carrying Additional Information !! wherein 2.2.2.2 is R2 of Router-ID , attention since 100.1.1.0 in R3 of OSPF Access-list 2 permit 172.16.20.0 route-map BGP2OSPF permit 10 MED : 200 R2# sh ip ro 100.100.100.0 Match ip address matches the access list or prefix list SW1 (config-if) # glbp 1 priority 120 !! Priority defaults 100 , the highest priority becomes the AVG , under equal priority, the maximum IP interface becomes the AVG . Default " AVG preemption" is off RR self-originated route ? Configuration example 2 : as-path access-list with route-map *time* Nov 05 2011 07:52 PM Port Vlans allowed and active in management domain Fa0/20 1,10,20,30 There are two ways to perform an inbound soft reset: 1. Soft reset using stored routing update information 2 , dynamic soft reset Address 5.5.5.5 Routing? The key point is that R2 , through the R2 deployment redistributed routing , routing information may be selected in different transmission routes between the domains. 17:57:27 Ethernet (Ethernet) was developed in the mid- 1970s by the Palo Alto Research Center ( PARC ) of the Xerox division . Xerox first invented is a 2Mbps Ethernet , and later and Intel and DEC co-developed a 10Mbps Ethernet , commonly known as (Ethernet II or Ethernet DIX). Later, IEEE through the 802 Committee (802 Committee) to Ethernet standardized as IEEE 802.3 . It is very similar to the Ethernet II .
