But what if the A route is an OSPF external route? 100 Preemption enabled, min delay 30 sec Active is local, weighting 100 It is used to preferentially send packets with high priority when the switch is blocked. Set ip next-hop 11.1.1.2 exit Configuration command AS65102 as a transit region ( trasit AS ), the AS inside BCDE running the OSPF , such that AS within reachable; D and C did not run Network Ip prefix-list 11 permit 11.11.11.0/24 route-map test permit 10 At the time, it is already " 200 i ", so doing prepend can only be inserted in front of 200 i , please pay attention to the difference from the previous one. The switches at both ends of the trunk need to use the same trunk protocol. BGP metric is set to IGP metric Ip dhcp snooping trust IP protocol number 88 Topology change mechanism On Demand stub Routes RFC1723 defines an acceptance control switch ---------- ? ? ? Complete the basic interface IP configuration . Add the following configuration on R2 : Under normal circumstances, Rl is possible to ping through 3.3.3.3 , but if R2 f0 / 0 port agent arp turned off, then it ping nowhere outlet associated with the use of static routing, the router will route to the destination address that is the local chain Road, so send arp request for mac of 3.3.3.3 , and Ip dhcp snooping limit rate rate Ip policy route-map PBR If R2 is added to the default route of R3 on the above basis, the data of the PC to the 10.1.13.0 network is still lost to R1 , which means that ip defaut-next-hop has higher priority than the default route. //The default community is not sent, so this command must be configured About the configuration of PVLAN : R4#show ip bgp 172.16.0.0 Router(config-dhcp)#default-router [host address] 3.3.3.3 A static route to the host Milne is added to the ROO . The next hop is the E1 port of Kanga . The purpose is to pass the bridge that is often congested. But found that Kanga will be sent to the host Default behavior: source IP address pair ( src-dst-ip ) Ip prefix-list 10 seq 5 permit 172.16.10.0/24 ip prefix-list 11 seq 5 permit 172.16.11.0/24 route-map test permit 10 The rules for BGP next-hop are as follows: Set ip next-hop 10.1.1.2 10.2.2.2 set ip next-hop verify-availability interface fast 1/0 1-4094 No-advertise STP topology change Fa0/20 ! HOLDTIME CISCO defaults to 180s ( 3 times KEEPLIVE timer ), which is included in the open message. Ip dhcp snooping Interface loopback1 The frame structure formed by the MAC sublayer is mentioned in the introduction above , including IEEE802.3 frames and ETHERNET_II frames. match. Such an approach will match community included 100: 11 routes. Aggregate-address 192.168.0.0 255.255.0.0 attribute-map test // Associate route-map test works on aggregated routes If an error occurs after receiving the open message, a Notification message is sent . If not Ip summary-address rip xxxx yyyy // Note that this summary does not support CIDR supernet . None Block all ARP requests or on the DAI untrust interface (note the separation from DHCP snooping 's untrust interface) Ip address 100.0.1.1 255.255.255.0 Some routes can be assigned a specific COMMUNITY attribute, and then BGP attributes can be set based on the COMMUNITY value instead of each route . The COMMUNITY attribute works for neighbors. After setting, it needs to be sent to the neighbor ( SEND ). Etc., then there is a prioritization between these methods: network>redistribute>aggregate Note that this principle is not used as a BGP routing routing policy. Length : indicates the full length of the BGP packet, including the header. 20 . Offset-list 1 out 10000 fastEthernet 1/0 Regular expression example: 2.2.2.2 Access-list 1 permit 100.1.1.0 100 AD value and back door R3#show ip bgp summary Path attribute Precautions: IP address : Disabled The aggregate-address command is used for BGP manual summarization. The following is a detailed explanation of all subcommands of the command. Note that this modification will take effect on all routes sent by R5 (the weight of all routes will become 100 ), and VLAN field, 15 bits are currently used 10 th, then the support up to 2 of the 10 power = 1024 th VLAN Of course, on R3 , the same effect can be achieved with the distribution list in the in direction. Or the above example, if we R1 on, of ping 1.1.1.2 REPEAT size. 1 1501 , at this time, R1 due to the generation of the IP packet is larger than Distance 100 192.168.12.1 0.0.0.0 1 RR transmitting the AS ( Transit the AS ) is divided into small units, i.e. reflection clusters Protocol overview *Mar 1 00:11:47.891: ICMP: echo reply rcvd, src 2.2.2.2, dst 192.168.123.3 Detailed rules If the access layer switch is connected to a single link, there is a single point failure of the single link failure. If any aggregation device is down, it will directly cause the downlink access network to hang. Vlan 101 Sw1(config-if-range)#channel-protocol pagp/lacp Sw1(config-if-range)#channel-group 1 mode desirable Ip community-list 11 permit 100:11 Of course, you can also associate the route-map after re-issuing the command and set the tag in the route-map . By default, only O and O IA routes in OSPF are redistributed into BGP. Show ip bgp 10.10.10.0 on R3 Apply ARP ACLs to DAI 3.3.3.3 IGRP for OSI networks Metric for redistributed routes Mobile routes Therefore than MED , 2 of MED small, 2 is the best path Another CASE that associates the static route of the outgoing interface : ^$ !! The default VTP prunnig is off OSPF 's neighbor command is not the same as EIGRP . After testing, in the Ethernet environment,ccnp route lab guide pdf, directly refer to the neighbor , and still send multicast hello. View and verify ADJ-RIBs-IN stores unprocessed messages from peers. The included routes are all available routes 10.1.13.1 Ip as-path access-list 1 deny _600$ Set next-hop specifies the address of the next hop , specifying the next hop of BGP . *Mar 4 07:02:23.473: DHCPD: relay information option exists, but giaddr is zero. Switch(config)# vtp mode {server | client | transparent} MED Dynamic routing protocol port number or protocol number 7 Interface loopback0 Switch(config)# ip route 0.0.0.0 0.0.0.0 192.168.255.2 R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. Configuration example 1 ( -RIP in a single routing protocol environment ) 100 i Show ip dhcp database Displays recent activity on the DHCP database The maximum number of seconds allowed before the HOLDTime router must receive a keeplive or update message 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 .
