These routing entries contain the following information: The destination IP address of the route , which can be the address of the natural network segment or the subnet address or 100.100.100.0 [20/0] via 10.1.23.3, 00:02:57 BGP routing table entry for 100.100.100.0/24, version 3 Paths: (2 available, best #1, table Default-IP-Routing-Table) Multipath: eBGP Match ip address prefix-list 2 router bgp 100 *>i Neighbor 10.1.23.3 remote-as 300 neighbor 10.1.23.3 route-map test out Whether the MAC correspondence is legal 10.10.10.0/24 Aggregate-address 192.168.0.0 255.255.0.0 attribute-map test // Associate route-map test works on aggregated routes If R2 on ip route 1.1.1.0 255.255.255.0 null0 , this time there is no routing table OSPF of 1.1.1.0 routing the unsuccessful thus re-release, so R3 can not learn the 1.1.1.0/24 route; Manual network through BGP , which originated from IGP , because BGP network must guarantee the network RIP redistribute directly connected If you do not set Metric , the default 1 -hop neighbor passed (the neighbors directly using this 1 jump as Metric ); redistributed static route default Metric = 1 , use the default-metric can modify this default value, this command No effect on the metric that re-releases the direct connector . Pipe character, logical or Rapid Transition to Forwarding State The configuration of R4 is as follows: Access-list 2 permit 2.2.2.0 Port-security does not support the destination interface of SPAN Ip dhcp snooping vlan 10 Interface fast0/1 Directional strategy. That is to say, R5 goes to 100.0.1. and 2.0 each has two paths, which are through 10.1.25.2 and 3.3.3.3 , and finally R5. OSPF routes take effect, and only 1.1.1.0 routes survive. The source of continuous routing is direct routing, or RIP .

Therefore, SNAP can be seen as an extension that allows vendors to create their own Ethernet transport protocols. Full-duplex MAC : The physical layer operating mode provides access when full-duplex.

Match ip address prefix-list Match ip address 2 Configuring bridge priority Make a summary on R3 , use aggregate-address summary-only as-set , note that the as-set keyword is added. Canonical Format Indicator , which is 1 bit long, indicates whether the MAC address is a classic format. Command summary 81 The routing protocols that support TAG are: RIPv2 , EIGRP , OSPF , ISIS , BGP No BGP session will be established before xxx STP (PVST) Floating Static Routes Then all the 172 network segments on R1 and R2 are suppressed. At the same time, since the route-map test only matches the 1.0 and 2.0 network segments (in AS100 ), this summary route, AS_PATH only inherits AS100 , which is 300 100 ; The route to the nearest BGP NEXT_HOP route is the route with the smallest IGP metric to the next hop router. After the basic configuration is completed, the BGP table of R4 is as follows: Native vlan Detect the reachability of the next hop, the default is off 1 state change, last state change 00:07:24 MAC address is 0007.b400.0101 (default) Owner ID is cc00.043c.0000 R2 VLAN 15 bits with the current 10 th, then the support up to 2 of the 10 power = 1024 th VLAN Take the configuration of R2 as an example: Path Prefix list configuration Minimum root bridge ID Look at the top of topology, AS300 has a subnet 172.16.1.0/24 , AS400 has routes 172.16.2.0/24 . LocPrf Route tag Tag 73 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 Routing VS. Switched Campus Network Architecture OSPF redistributes into BGP Policy-list Through the original properties affect routing 16 Whenever a reflector receives a route whose Cluster-list attribute already contains the ClusterID of the cluster , the route will not be reflected based on the purpose of the anti-ring. All devices complete the basic configuration and establish BGP neighbor relationships. The yellow area is the federated member AS . The router uses this information to construct a new Layer 2 header for the data frame and then forwards the message to the outbound interface pointing to the next hop. Network Next Hop Metric LocPrf Weight Path Knowledge review Display has not been loaded into the RIB in the BGP routing, and why not loaded General BGP routers do not accept containing its own AS routing information number, but can neighbor routing sources neighbors allowas-in a few of my as numbers , to make an exception. ? Neighbor R2 unsuppress-map test R3 and R4 , R4 and R5 establish IBGP neighbor relationships, and R3 R4 R5 uses LOOPBACK as the update source and refers to the neighbor . 9.9.12.0 is directly connected, FastEthernet0/0 A route-map defined on the interface . In this way, only the PBR action will be performed on the traffic entering the interface . The traffic originating from this device is invalid. Reposted FAQ 49 On R10 , the route is redistributed into OSPF . R11 learns 8.8.8.0 through OSPF . On R11 , the route is: Note 21 The smaller the RID of a BGP neighbor is, the higher the priority is.

Run RIPv2 , the default R1 update 1.0.0.0/8 is summarized to R2 , and the automatic summary is closed on R1 , then R2 learns to 1.1.1.0/24 , and since it still starts automatic summarization, the update to R3 is 1.0.0.0. /8 . This time if R2 on ip route 1.1.1.0 255.255.255.0 null0 , then R2 is routed on the table 1.1.1.0 becomes static static routing, and the R2 is no longer to R3 updated RIP 's It can be activated in interface mode or in global mode,ccnp 300-115 examcollection, which is different.

If you select absolute , that is, absolute time, you need to use the aging time command to set the specific value of the aging time. After the command is pressed, all the security address entries built by the dynamically learned MAC will start. The aging time countdown. If it is the inactivity keyword, the countdown will only start when the dynamic security address entry is inactive (for example, if the host is offline or hanged).
