R3#show ip bgp summary Data ( DATA ) If the MED of the received or generated route is empty , set the MED to 0 when advertising to the IBGP Peer . BGP of AS plan shown in FIG. Summary 1) 2) two points is MED in IBGP passed without problems (not lost) between, but EBGP between transfer depends on whether the route originated in themselves. ? The behavior of the router is hop-by-hop. Each router along the path to the destination network must have a route to the destination. Questions R3 announces 192.168.1.0 , 2.0 , and sets the community attribute of 1.0 to no-adv. Modify the default value of the MED value BGP 10.1.13.1 For example, on a PC , statically bind the gateway IP and the MAC of the gateway with arp-s to prevent arp spoofing, or use the command arp for binding on the network devices of the key nodes . Experiment 3: Weighted extension R1#sh ip b 1.0.0.0/24 is subnetted, 1 subnets Knowledge review By MED influence route selection If R1 turns off auto-summary and network 1.1.1.0 mask 255.255.255.0 , then R2 can learn BGP route 1.1.1.0/24 192.168.2.0/24 Ip sla monitor responder Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only ARP Receiving behavior Must be a zero field. In CISCO IOS 12.2(33)SXH and subsequent versions, we can deploy port-security and 802.1X on the same interface. And before this software version: Command Clear ip bgp soft out // Outbound soft reset, resend update message to all neighbors Note 21 There are two ways to perform an inbound soft reset: 1. Soft reset using stored routing update information 2 , dynamic soft reset Port-channel interface cannot be the destination interface of SPAN In general, a Layer 3 switch contains two types of ports: Layer 2 interface L2 and Layer 3 interface L3. We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Match ip address Suppose we have several subnets: On Topology change mechanism (delivery) R4 on the show ip bgp 172.16.0.0 None uses the distribution list or the access control list deny 521 port. LocPrf s suppressed routing entries, such as doing route summarization, suppressing details In this way, the entire network is interconnected. Note that when redistributing routes to OSPF , redistribute rip subnets , this subnets RIP re-advertises routes to OSPF : SW3 's Fa0/3 from Listening to Forwarding takes 20+30S Sw(config-vlan)#private-vlan community DHCP relay R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. ID . MST CASE1 : Manual summary Interface loopback1 The front is to use static routing. If dynamic routing protocol is used, the situation is different. For example, IGRP or EIGRP , the network specified by the ip default-network command must be obtained through IGRP or EIGRP (declaration, learning or redistribution). ),ccnp switch resume, the default route can be dynamically passed to other protocol routers. Regular expression // AS200 is the Primary AS and is used to configure the BGP process. OSPF SW3 is small), so the interface connected to SW2 on SW4 wins and becomes RP .

Ip route 100.1.0.0 255.255.0.0 null0 1.1.1.1 Vlan 10 At the same time, the two routes are marked in the BGP table: " *> ", indicating that the two routes are valid , and the best or optimal, best , so they will be passed to the IBGP neighbor of R3 . That is R4 If the interface is trunk , set the trunk protocol type switchport trunk encapsulation dot1q switchport mode trunk In update their ARP table or will receive the ARP before forwarding the message out to check legality, mainly to see the ARP packets in IP and The TAG field ( 32bits ) is only present in the external LSA . Metric Only vlan1 and vlan10 Knowledge review 8 bits SW1(config)# interface fast0/23 200 i Origin IGP, metric 0, localpref 100, valid, internal, best Obviously this method is too poorly scalable. 3.3.3.3 Add configuration on SW2 : (global configuration mode) ip dhcp relay information trust-all Notifacation packets , resulting in session is interrupted; it can be re- AS on the border router IN strategic direction. Load balancing C 10.1.12.0 is directly connected, Serial0/0 *> 100.0.1.0/24 Redistribution is to look at the routing table, that is, for example, I redistribute OSPF to EIGRP , then the route must be in my routing table, and must be OSPF routing before it can be injected into EIGRP . In addition, there is a small problem here . The link between R1 and R2 , although it does not see the OSPF route on it in the routing table of R2 , it was successfully re-released into RIP and learned by R3 . This is because of this direct link (interface) has been R2 's OSPF process network up , namely by OSPF learned to, and is a direct link, and therefore can be re-released.
