ccnp 300-115 pass4sure

The so-called seed metric refers to when I use a route to re-publish from an external routing protocol to this routing protocol, if the metric of the route is not manually specified , the default metric is used . Look at the following table (the following table is a recognized default value that can be modified using the default-metric in the routing process ): Ip dhcp pool vlan10 network 192.168.10.0 /24 The solution is as follows: 1. On the R3 ,ccnp 300-115 pass4sure, declare the directly connected network segment of 10.1.13.0 into OSPF , and R5 is the same; 2. Modify it on R3 . Dynamic routing protocol port number or protocol number 7 Determine if the frame has a VLAN tag . Ip default-network 192.168.1.0 ICMP redirect 8 In the one local BGP routes advertised to EBGP the Peer time, whether they carry MED values , need to be determined under the following conditions ( not EBGP The next hop of the A segment becomes R4 , which results in a suboptimal path. Also, on R3 , the re-release of process 1 to process 2 fails. * >i11.11.11.0/24 HOLDTIME CISCO defaults to 180s ( 3 times KEEPLIVE timer ), which is included in the open message. Activate Port-Security (on the trunk interface) Other configuration commands When a link needs to carry multiple VLAN information, you need to use trunk to implement You can see these two routes by viewing the BGP table on R3 . Ip route 1.1.1.0 255.255.255.0 serial 0/0 Use the sticky MAC address on the port-security interface 1.1.1.1 Router bgp 345 External Ip nat inside source route-map nat1 interface serial0/0 overload ip nat inside source route-map nat2 interface serial0/1 overload ip nat inside source route-map nat3 interface serial0/1 overload Flex links and Port-Security are not compatible with each other Knowledge review Path Ip route 172.16.1.0 255.255.255.0 192.168.12.1 100 Encapsulation Status BGP only passes the route that it uses, that is, the route that it considers to be Best to the BGP peer. As mentioned above, a route is allowed to carry multiple community values ​​to form a community list. If you want to delete one or several community values, for example, Configuration Set origin set tag Local origin Bridge using these 4 steps to save each port received the " best " of the BPDU a copy. When each BPDU arrives, it will check according to this 4- step decision step to see if it has a better BPDU saved on the port . If it is, it will be updated. 100 2 Suboption type The configuration of R2 is as follows: Ip dhcp snooping vlan 10 Interface fast0/1 The Layer 2 switch searches for VLAN configuration information based on the destination MAC address and VLAN ID of the frame, and determines from which port the frame is sent out. ( Optional transitive ) The type parameter in the above command is used to indicate the hardware type of this hardware address. If type is 1 , the type is ethernet , if type SA sends the original switch MAC of the frame The non- root bridge receives the TCN on its designated port Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale 3.5 RSTP (802.1W) Let's start with the above picture, starting from 172.16.0.0/16 . The next network number we see is 172.16.10.0/24 , which is obviously obtained after applying the VLSM variable length subnet mask. a 172.16.0.0/16 a master class this network subnet . So the so-called subnet, we can understand as a network number obtained by "stretching" the mask or borrowing from the host bit based on the default mask length of the category to which the network number belongs. In fact, 172.16.0.0/16 is an interval that includes 172.16.10.0/24 .
