ccnp switch 300-115 kevin wallace pdf

The BGP router appends its AS number to the AS_PATH only when the update message is sent to another AS ( EBGP peer ) . This sentence also implies another meaning, that is, if you want to modify the AS_PATH attribute, you must execute the policy on the AS border router, and the policy of modifying the AS_PATH for the IBGP neighbor is invalid. Wherein SW1 is as follows: Optional delivery to simplify the execution of routing policies Ip address 192.168.10.254 255.255.255.0 SW2 is the core layer switch, deploying DHCP relay The comparison principle of OE2 is first compared to the external metric of OE2 . If they are equal, further comparison of the internal metric is the metric to the ASBR . No synchronization no auto-summary Network The VTP Server and clients synchronize the database with the highest revision number; In the full-duplex mode,ccnp switch 300-115 kevin wallace pdf, the transceiver can be directly sent and received without pre-determining the busy state of the link. When the number of prefixes received from the neighbor exceeds the maximum number 300 of 90% (default 75% ), generating a message log Lowest sender port ID We found that the route to 100.0.1.0 and 2.0 , the next hop is 3.3.3.3 , because of these two paths, original ? In addition, if there are multiple links between two EBGPs and use their respective Loopback ports as the source , you should also pay attention to the configuration. Ebgp-multihop 2 (because loopback spans two routers, including this one ), and must also refer to static routing to the other's loopback interface. ) DAI working mechanism Routing time: The time elapsed since the last time the routing entry was modified. The routing time is reset to 0 each time the routing entry is modified . Router bgp 100 The setting of the weight value can only be done locally and cannot be passed to any BGP neighbor. When BGP routes are redistributed to the IGP , the iBGP routes are not redistributed by default . Only EBGP routes are re-advertised . bgp redistribute-internal is required to make the iBGP routes re-released. External Native vlan In SW3 created on 10 , 20 , 30 three VLAN Router ospf 100 If the static keyword is not used , the ARP packet will be matched by the ARP ACL . If there is no match, the DHCP snooping database security entry will be checked again. If there is a valid entry, the data will be released. If not, discard it. Router bgp 345 Ip route 2.2.2.0 255.255.255.0 192.168.123.2 Sw(config-if)#switchport mode private-vlan promiscuous sw(config-if)#switchport private-vlan mapping 100 201,202 sw(config)#interface range fa 0/1-2 [Note] If the interface is passive , but at the same time the network interface in the routing process, the interface will not attempt to send updates or establish neighbor relationships, but the network segment where it is located will still be declared into the routing process. Ip prefix-list 1 permit 100.0.1.0/24 * 192.168.34.3, from 192.168.3.1, 00:09:32 ago, via Serial0/1 Route metric is 20, traffic share count is 1 If it is injected through the aggregate-address command, next-hop is equal to the update source IP of the summary router . RIP message format 31 In this way, the entire network is interconnected. Note that when redistributing routes to OSPF , redistribute rip subnets , this subnets Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only Path cost Ip community-list standard del permit no-export ip community-list standard del permit 100:11 BGP cannot automatically discover the neighbors as the IGP . The IP address of the neighbor is specified by the local BGP neighbor command. The source IP address of the BGP connection is the outgoing IP address of the traffic . Note that only the neighbors locally configured IP and neighbors for BGP source connection establishment IP is the same, BGP connection in order to be properly established, at the same time, to ensure that only one party can meet the conditions.
