You must use neighbor in the BGP process to specify the BGP peer . They exchange routing information, as well as related attributes, not link status. Route-map test permit 10 Switch(config-if)# spanning-tree portfast [trunk] Debug ip dhcp server {events | packets | linkage} Enables debugging on the DHCP server When a data frame is sent from the Hybrid port, the switch determines whether the attribute of the VLAN on the port is Untag or Tag . If it is Untag , first strip the VLAN tag of the frame and then send it ; if it is a Tag , send the frame directly. Data forwarding mode 13 Bridge ID Note that at this time, the routing table is used to recursively find the route to 10.1.12.2 , so there must be reachable routes in the routing table. C and D are not aware of 1.1.1.0 (they only run OSPF , not running BGP ), and thus become a routing black hole. Note that although the CD is not running How to perform non-equivalent load balancing? In this figure, the bandwidth of the uplink interface of R2 is actually not equal. The penalty value of all normal routes is 0 , and the penalty value is added instantaneously. Community number in aa:nn format Add to the existing community Interface fa1/0 Metric LocPrf Weight Path 0 100 0 200 i To other neighbors You can use ^ at the beginning of a range to exclude all characters in the range, or you can use an underscore _ to specify an interval. ( Well-known discretionary ) The bandwidth of F0/0 port is 100M , and the bandwidth of S0/0 port is 1.544M . Except for the next time, it is just 1:60. 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). ), the default route can be dynamically passed to other protocol routers. RIP-2 MD5 Authentication Match ip address prefix-list 1 set weight 100 100 i Circuit-ID suboption fields Neighbor 10.1.12.2 route-map test out Floating Static Routes Ip route 2.2.2.0 255.255.255.0 192.168.13.1 Then, in order for R3 to dynamically learn the routing of production and office servers, it is now necessary to redistribute these two static routes into OSPF . Of course, there are tricks when re-publishing. Redistribute local direct connection network segment into BGP , MED value is 0 ; redistribute local static route into BGP , MED value is 0 Ip address 100.0.1.1 255.255.255.0 100 9.9.12.0 is directly connected, FastEthernet0/0 Switch(config-if)# ip address 192.168.10.254 255.255.255.0 Ip arp inspection trust After completing the configuration, R2 show ip route Activate the portfast feature for a specific interface Route metric is 0, traffic share count is 1 As an update source, send it to R3 . The default keyword has a lower priority than the detail route. Access port processing frame process RIP message format 31 After DHCP snooping is enabled on the switch , the switch uses the DHCP interaction content that is "listened" on the untrust interface to form a table: The number of messages received by MsgRcvd from neighbors Option packet structure: Communicates with all other ports Router bgp 200 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 By using route tags in RIP , you can control the redistribution of related routes in other protocols. When republishing to other protocols, RIP routes simply compare the tokens assigned to them without comparing the entire route. Cisco Private Start a TCP connection. Prepare enough resources when BGP is enabled Metric RSTP is able to quickly transition between edge ports and point2piont links. The link type of the RSTP is automatically obtained through the duplex state of the interface. If the interface is half-duplex, the link type is the shared port . If it is full-duplex, it is point2point . 200 port-security does not support etherchannel the port-channel interfaces Initially,ccnp switch exam objectives, R3 can learn three loopback routes from R1 and 192.168.12.0/24 routes. Now we don't want R3 to learn the route to 192.168.3.0/24 , then we can configure it on R2 as follows: SW2 receives the BPDU from SW3 and calculates its own Fa0/2 as the root port. RIP-1 compatibility RIPv2 sends updates in the form of broadcasts, enabling V1 to receive MTU problem ? S0 192.168.12.1/24 r1 Next Hop Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only R2 , R3 , aiming RIP create static routing domain summary route, point null0 , while only these static routes redistributed into OSPF , and indeed can play a sub-optimal paths to avoid the question, but: About the rate_in_pps parameter: Statically configure a dhcp snooping bingding dabase entry. The command is configured in privileged mode. After " 10.1.20.0 " is passed to R2 , since the updated subnet is consistent with the R2 interface main network, R2 receives the update, and uses the interface mask /23 as the mask of the received RIP subnet, then R2 local loading This RIP route is 10.1.20.0/23 . In fact, the prefix length of the route is wrong. We can configure a secondary address on the R2 interface. In this way, RIP will use the mask of the secondary address (if configured) to receive the route. For example, configure R2 with 10.1.123.222/24 .
