200 ? We expect the effect of the above configuration is implemented R1 to 100.0.1.0 routing setting MED = 100 , 2.0 disposed MED = 200 is , while R2 to 100.0.2.0 disposed MED = 100 , 1.0 arranged MED to 100 , respectively, to the respective property The EBGP neighbor takes effect, so the MED attribute will be passed along the route in AS345 and finally arrive at R4 . Of course it includes information such as object MAC address , contents of the destination interface . In this case we need only one data stream (Flow) in the first packet do process Protocol overview Off: EtherChannel not configured on interface Hostname R5 Show ip bgp route prefix switchport trunk encapsulation dot1q switchport mode trunk Come to the same topology change. 10.1.13.1 The Response packet contains a maximum of 25 routing entries. 16 bits Based on packet load balancing, all packets are rounded on the outgoing link. If you want to use message-based CEF load balancing, you need to configure this command on all outbound interfaces. The buddy experiment has verified that it can indeed be per-packet load balancing. Example 2 : 100 i BGP does not update the route periodically. It is updated only when needed. Because the route of the public network may be turbulent, there will be a certain waiting time for triggering the update. The IBGP peer is 5S . The EBGP peer is 30S . During the time, BGP can still collect routing information, so BGP convergence will be slower. R3-R4 ; R4-R5 ; R3-R5 maintains IBGP neighbor relationships and uses their respective LOOPBACK ports as update sources and establishes The Permit/deny keyword has a different role in different deployment scenarios. LocPrf Y Address-family ipv4 unicast 10.1.13.1 *>i10.1.12.0/24 32 bits If there are no dynamic and static routes on R2 , and the configuration is as follows: 5.5.5.5 The configuration of SW1 is as follows: Use CDP to detect next-hop IP reachability in PBR environment (without optional parameters) Definition of 1042 . The most commonly used encapsulation format today is the format defined by RFC894 , commonly referred to as Ethernet II or Ethernet DIX . Trunk port processing frame process ? Match ip add pre 1 R1 and R2 are private partners. Some special traffic may need to be protected. Therefore , the dedicated line between R1 and R2 is added. If you want to ensure the traffic between 1.1.1.0 and 2.2.2.0 is exchanged through the leased line (running) the RIP ) away, when the green DOWN , only to take the following multi-access network. Basic experiment Establish BGP neighbor relations PAgP is a Cisco propretary protocol LACP is IEEE 802.3ad standard 20 CISCO data forwarding mode 13 Logical aggregation of similar links If there are routes with the same prefix as follows (the default is sorted in reverse order of route acceptance order) Set ip default next-hop 10.1.12.1 Other configuration commands: Set ip next-hop The mask of the destination address. Router ospf 100 DAI working mechanism Router bgp 100 If the DHCP discovery message sent by the client does not contain the client-identifier , the hardware address can be used to identify the terminal device. The configuration commands are as follows: Family Identifier ) Configuration example SW1 (config-if) # glbp 1 priority 120 Last update from 192.168.101.10 on Serial0/0, 00:12:46 ago Routing Descriptor Blocks: Principle of ARP protocol Scp: Database agent URL Ip prefix-list 1 permit 11.11.11.0/24 route-map test per 10 Cisco Private Activate the portfast feature for a specific interface 10.1.25.2 If the interface is trunk , set the trunk protocol type r route is not loaded into the RIB table, for example due to AD values,ccnp switch practice test, etc. When a local BGP route is advertised to an IBGP peer , the MED value must be carried . Metric 100 Ip dhcp snooping information option allow-untrusted The AS_SEQUENCE attribute will be passed to R7 along with the route 11.11.11.0 , so the packet is captured on R7 . The attribute of AS_CONFED_SEQENCE is not visible in the route of 11.11.11.0 , so the external AS treats the federation as a single AS (outside I don't know the situation inside the federation) Route reflection clusters include reflectors and their clients 1,10,20,30 Can be configured in global mode or in interface mode, the difference is as follows: global configuration: spanning-tree portfast bpdufilter default Hello time 3 sec, hold time 10 sec Next hello sent in 1.280 secs Router bgp 100 OPEN message Configuration Example 3 (at a single routing protocols -OSPF ) If the MED of the received or generated route is empty , set the MED to 0 when advertising to the IBGP Peer . Network Below is an example: Hostname R5 If there are no dynamic and static routes on R2 , and the configuration is as follows: Field ... Access-list 1 permit 172.16.10.0 Routing feedback 42 / / used to define the condition prefix to be injected 100 Vlan 10 The associated PC service, that is , the data frame whose source is the MAC , can enter the interface. COST community : RFC1771 A Border Gateway Protocol 4 Faster Aging of Information 100 MTU problem Neighbor 10.1.23.3 send-community neighbor 10.1.23.3 route-map test out About the recovery of err-disable after being punished : The cache extracts the destination interface , destination MAC address, etc. , which greatly speeds up packet forwarding. 10.1.13.1 All devices complete the basic configuration and establish BGP neighbor relationships. The yellow area is the federated member AS . 3.3.3.3 ? The above figure only makes basic BGP configuration, releases 1.0 and 2.0 on R1 , does not summarize, and 1.0 and 2.0 BGP routes received by R4 . 5.5.5.5 It is recognized that the attributes must be followed to describe the sequence of AS numbers that must pass through the target network . The most important role is anti-ring. If the BGP speaker finds that its AS number appears in the AS_PATH of the received BGP route update , it indicates that there may be a routing loop, and the routing update is ignored. Another important role is that in the BGP routing, as the measurement of the AS hop count, of course, the fewer ASs included in the AS_PATH , indicating closer to the destination.
