10 FastEthernet0/1 Sw1(config-if-range)#no switchport // Configure the L3 interface Local-as Router bgp 345 The following are five types of BGP packets and packet parsing: ---------- A match to a start, the end of any single character string, such as A0 , a! Etc. None Failure case analysis 1. where 3 means that my own network of 0 100 0 R1 and R2 are private partners. Some special traffic may need to be protected. Therefore , the dedicated line between R1 and R2 is added. If you want to ensure the traffic between 1.1.1.0 and 2.2.2.0 is exchanged through the leased line (running) the RIP ) away, when the green DOWN , only to take the following multi-access network. Redistribute ospf 3 subnets route-map OSPF3to1 router ospf 2 CASE1 : Origin attribute (priority: IGP > EGP > Incomplete ) Not advertised to any peer First select root , the SW1 with the smallest MAC address of the switch wins and becomes root. Of course, on R3 , the same effect can be achieved with the distribution list in the in direction. Preemption enabled, min delay 30 sec BGP , the IBGP neighbor relationship is established between the BEs . If A has a network segment 1.1.1.0 , A injected into the BGP , and transmitted to the EBGP neighbors B , 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 C Origin IGP, metric 0,ccnp route exam 9tut, localpref 100, valid, external, atomic-aggregate , best SW1 still turns on dhcp snooping and inserts option82 Match ip address 1 Router# sh ip bgp summary When ISP1 when down, and GW connected ISP1 interface not DOWN (such as closing ISP1 the CDP ), since the GW lost ISP1 of CDP Router bgp 100 Solution 2 : Free arp – LoopGuard and RootGuard cannot be enabled at the same time About UDLD 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 . Root received the TCN , sent back a TCN ACK to C . Case: Implementing intranet export data diversion through PBR BGP is designed to AS transfer routes between, so it is actually a hop AS . This is the black hole routing problem, in order to avoid this problem, consider the BE on the BGP routes redistributed into OSPF to solve, but to do so the consequences are unpredictable, after all, BGP routing entries carried is quite enormous. Another solution is to require the routers in the AS to run IBGP and implement IBGP full interconnection. Then the routers in the Transit AS can know the BGP routes, thus solving the problem of routing black holes.
