? By default, only one BGP process can be started on a single router and can belong to only one AS . DUAL AS allows us to run a secondary AS under the primary AS without terminal BGP connections , thus providing a mechanism for network migration. DHCPsnooping Scp: Database agent URL DTP enables trunk negotiation between switches Path However, we found that R4 did not pass these two routes to R5 , which is because of the effect of IBGP 's horizontal splitting principle. According to the IBGP split horizon principle, a BGP router, if it learns BGP routes from its IBGP neighbors , will not be able to pass these BGP routes to other IBGP neighbors. The reason for setting this rule is that BGP anti-ring needs to resort to 1,10,20,30 CISCO data forwarding mode 13 R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. Windows system), at the same time reply a Gratuitous ARP response to inform the peer that there is a duplicate IP address. The LP field is all there, but it will assign a default value to this route locally, which is 100 , and then pass it to its own IBGP. Due to the lack of a feedback mechanism, the interface connecting A to Root from Listening to Forwarding needs to experience a delay of 15*2s . In this case A , B , C the second line on the user traffic problems (since D in better received BPDU after the P1 port block ,ccnp tshoot topology 2018, this time ABC corresponds A root port transitions to the forwarding are in the network before the " buffer zones " ) Match ip address One way is to establish a fully interconnected IBGP 100 .* Next Hop For details on the related fields of the BGP table, see the show section of the BGP Configuration section of this document. The BGP configuration of R2 is as follows: Application 66 TCN BPDU Policy-list is only supported in BGP . Other IP routing protocols do not support this feature. Routing Protocols The LP attribute of the route is preserved throughout the federation 200 i Ok, then let's start the experiment below: We will find that when the topology changes, the TCN will be generated . However, in some cases, the transition flooding of the TCN may have an unnecessary impact on the network . The interface connected to the PC terminal device on the access layer switch is set to portfast network can be optimized to a certain extent, prevent the PC interface of the switch due to switch updown and excessive the TCN .
