SW1#show int trunk Next Hop Link type Link types basic concept The RID is the largest IP address on the router and tends to be assigned to the loopback address. It can also be set manually by the bgp router-id command. If a path contains an RR attribute, the route generator ID ( originator ) will replace the RID in the optimal path selection process. 5.5.5.5 ( metric 2 ) from 5.5.5.5 (5.5.5.5) Router bgp 123 BGP table version is 3, local router ID is 3.3.3.3 Passive-interface configuration Other configuration commands Portfast Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only Sw(config)#interface range fa 0/3-4 When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 4.3.2 Message Type 35 Spanning Tree Protocol *>i 3.3.3.3 200 100 0 100 i Definition of 1042 . The most commonly used encapsulation format today is the format defined by RFC894 , commonly referred to as Ethernet II or Ethernet DIX . R1 , R2 , and R3 run RIP , and 1.1.1.0/24 on R1 is not directly announced. On R2 : Path The frame structure formed by the MAC sublayer is mentioned in the introduction above , including IEEE802.3 frames and ETHERNET_II frames. The security address entry thus formed (which is SecureSticky ) will not be lost even if the interface is flipped. If wr saves the configuration and the command is written to config.text ,ccnp tshoot hsrp track, the security address will not be lost even if the device is restarted. Port R4 to R3 configured as Client , then it will be able to break through the limitation of split level, will learn from R3 route reflector to R5 , will learn from R5 route reflection of self- R3 . Let's look at R5 of the BGP table: Y Route summary technology background R3 receives two routes, respectively carrying the community attribute as above. Now, we only want to delete the no-export attribute of the 11 route . ! !

Instead of using 802.1D , pass the message to root and then root Communicates with only promiscuous ports Interface configuration: spanning-tree bpdufilter enable When 10.4.0.0 is hanged , C will immediately send a route poisoning message ( 10.4.0.0 16 hops) and then advertise it; Ip route 100.1.0.0 255.255.0.0 null0 Neighbor 10.1.12.2 advertise-map RP1 non-exist-map RP2 Here we are talking about is the switcher, as we all know, is not recognized by the switcher Layer 3 packet, which they will not see a three-tier I head, but this does not affect a switcher own IP address. On the router, we configure the IP address of the physical interface of the router , and the second layer Set the interface cost This is a very typical scenario. GS_SW is an aggregation layer switch that runs OSPF with the core switch . The GS_SW needs to advertise the network segment corresponding to the VLAN to be hanged , so that the core switch can learn the relevant routes. Then, once GS_SW announces the network segment corresponding to these VLANs in the OSPF process , the corresponding SVI interface will flood the OSPF HELLO message to the VLAN , and these messages are actually redundant.
