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. These two attributes are used to prevent ringing within the federation and member AS . What package? Load balancing Interface loopback0 We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Here are a few concepts to make clear: Route-map LP permit 20 match ip address pref 2 set local-preference 200 If a designated discarding interface issue proposal after, did not receive Agreement , it will slowly transition to the forwarding state, this process is a traditional 802.1D the listening-learning-forwarding process. This situation may occur when the peer switch does not understand the RSTP BPDUs or the port of the peer switch is blocked . This address of the neighbor must be IP reachable As Primary the AS , 201 of Secondary the AS , R2 can be maintained in the original R1 of BGP case of updating the routing and connection is not affected, DHCP overview Use CDP to detect next-hop IP reachability in PBR environment (without optional parameters) CISCO Note: The DHCP option-82 feature is supported only when DHCP snooping is globally enabled and on the VLANs to which subscriber devices using this feature are assigned. Sw1(config-if-range)#channel-group 1 mode desirable Sw1(config-if-range)#no shutdown 2 : RIP-2 ; Once the port-channel interface is established, it forms a logical interface, and subsequent configuration of the interface is in the port-channel. Single match includes a plurality of conditional statements, logical or operation; multiple match when the statement, using the logic and operation. PVLAN considerations Metric LocPrf Weight 5.5.5.5 Ospf rip static ---------- The rules for BGP next-hop are as follows: <100-500> Community list number (expanded) expanded Add an expanded community-list entry Local updater ID is 0.0.0.0 (no valid interface found) If a DHCP relay is also deployed on the switch, the switch adds the relay address to the DHCP packet. Vlan 10 Aa:nn additive internet local-AS Is 2 , 3 with AS the first comparison, 2 is MED small it is preferable; 2 with a further comparison, since the opening of the always-compare-med Rule validation ( AS_SET type AS_PATH , i.e. {} in the AS number in AS_PATH when calculated as a hop) BGP routing table entry for 11.11.11.0/24, version 2 Access-list 2 permit 10.1.2.0 route-map cisco permit 10 MED , choose 3 ? R3 , R4 , and R5 each create a LOOPBACK interface with an IP address of xxxx and x is the number of the router. Match ip address prefix-list 11 set community 100:11 Note 21 The configuration of R2 is as follows: 100 Show ip route dhcp Displays routes added to the routing table by DHCP The election of the root bridge will not be said. Next, look at the two interfaces of RP and SW2, and both will receive the BPDU , and the BPDU received by the interface connected to the root will be received . Configure an interface as a passive interface: On: channel member without negotiation ( no protocol ) The IGP Origin, Metric 0, localpref to 100, Valid, Internal,ccnp tshoot lab topology, Best Originator: 1.1.1.1, the Cluster List: 2.2.2.2 One thing to note here is that ip bgp-community new-format is used to convert the display format of community in CISCO IOS . When using regular expressions in the extended community-list list, the filtering results will vary depending on the format choice. 32 bits Since the AS_PATH attribute does not change within the AS (only when the route leaves the AS ), the AS inner loop has a horizontal splitting mechanism, and the route reflector actually relaxes the horizontal splitting principle . This will bring some hidden dangers to the loop. Therefore, the route reflector needs to use the following two attributes to prevent loops: Below we summarize some of the key points of the router about route lookup: This path. And because there is no RIP route in the routing table , the natural RIP re-release to OSPF fails, and even worse, R4 about Route Tag Tag Interface s0/0 After R2 show run , I found: Update-source inQ number of messages waiting to be processed from this neighbor Bgp bestpath as−path ignore This command, if configured, skips this rule If the TCP is successfully established, the BGP process sends an Open message to the neighbor and enters Opensent. Route is punished by dumpend Redistribute ospf 1 match internal external 1 The route of ( permit ) will be filtered and the other will be released. Network 10.1.25.0 0.0.0.255 area 0 Port Security : Enabled ^10[012349]$ If multiple candidate default routes are specified using ip default-network , then the lowest AD will become the default route and set as the default gateway ( gate of last resort ).
