Use ip community-list to match the community value ? Display has not been loaded into the RIB in the BGP routing, and why not loaded Configuration example 2 ( -RIP in a single routing protocol environment ) IP policy routing is disabled RouterID : 172.16.13.1 In the federal scope, the member AS number is pushed into the AS_PATH , but not published outside the federation, and the AS_PATH of TYPE3 , 4 is used . 200 i Access-list 1 permit 192.168.1.0 R1(config)# access-list 1 deny 172.16.32.0 R1(config)# access-list 1 permit any ? Both R1 and R2 are connected to the 2.2.2.0 network. At this time, R3 goes to ping 2.2.2.2 . Because the static route of the outgoing interface is used, R3 thinks that 2.2.2.0 is a locally connected network, so ARP request is sent , R1 , R2 , can receive the request message, and both respond to the request message (the premise two The problem that the static route associated with the outgoing interface is re-released. Path Control Overview A advertises the detailed route to B , B advertises the detailed route to C and D , and C advertises the summary route. At this time, the summary route will be transmitted to B in addition to being notified to D , and this may cause problems. Therefore, you need to filter the summary route on the IP distribution-list x of neighbor B on C. Otherwise, a routing loop will occur. In 802.1D , the TYPE field uses only the highest and lowest bits to indicate TC and TC acknowledgment, and RSTP extends this field: Toxicity reversal For example, R1 redistributed into direct on the OSPF , with out distribution list can be filtered out direction 1.1.1.0 this external routes. But R1 redistributed incoming routing, if R2 with the out distribution lists direction tried to block R3 accepted routes or LSA , you can not, because this is not a local external routes originating. Configuration and implementation Advanced Features basic concept Active is 10.1.1.252 (primary), weighting 100 (expires in 7.028 sec) Arp replies sent: 1 IP routing table The maximum survival period in the discard BPDU before the bridge used to store BPDU time default 20S . If consecutive receive 10 th bpdu * i100.0.2.0/24 : Disabled 10.1.34.3 from 10.1.34.3 (3.3.3.3) 100 Looking at the above picture, we assume that both switches A and B run DAI , and both PC1 and PC2 get the address through the DHCP server. At this time, for PC1 , only the DHCP snooping database on switch A has its IP+MAC . Bind, switch B does not. Thus, if A and B interfaces between the DAI the untust , from the PC1 of ARP packets, the switch will be B discarded, because it is believed these are illegal packets,ccnp tshoot materials, this way, PC1 and 2 communications on the problem It is. It is recommended that A and B interfaces are provided between the DAI ofTrust .
