ccnp switch 642-813

Assuming the environment is like this, R1 re-releases A route into OSPF , then R2 will learn this OE2 in its own OSPF process 1 . BGP configuration Backup port: Discard status. A backup of a specified port occurs when a switch has two ports connected to the same shared medium. RFC1722 Set the timer of STP EGP R3 and R5 both advertise the routes of the same network segment to R4 . If the first eight rules cannot be determined, if R4 is configured: 100 i -------------- Ip route 0.0.0.0 0.0.0.0 serial s0/2 PAgP mode: 10.1.20.0/24 This route is updated by R1 with " 10.1.20.0 ". This is because the subnet mask is consistent with the update interface mask /24 . The v1 update package does not contain a mask. The updated subnet only. number. Priority , which is 3 bits long, indicates the priority of the frame. The value ranges from 0 to 7. The larger the value, the higher the priority. 16/32 bit Passive interface The network already exists in the routing table. length When UDLD detects a unidirectional link failure, it administratively shuts down the interface and prompts the user. Unidirectional links can cause various problems, including spanning-tree topology loops And SW3 on the same case Next hop 10.1.12.2, FastEthernet0/0 valid adjacency By default, no rate limit is configured. Vlans in spanning tree forwarding state and not pruned Switchport port-security maximum 1 Multilink Multilink-group interface *Mar 16 17:09:21.858: DHCPD: inconsistent relay information. R8 to re-advertise 8.8.8.0 into the BGP , has spread to R10 , the R10 on the route AS_PATH is 98? , Port-Security and Sticky MAC Address Displays all BGP routes received from the specified neighbor (original route before the local inbound policy is executed) The next hop (the Next Hop) - if present , it identifies a better than advertised router address of the next hop address. In other words , the next hop address it noted , that in the same measure than - advertised subnet router closer to the destination. If this field is set to all 0s (0.0.0.0), the address of the advertising router is the optimal next hop address. Exit B performs the corresponding checksum confirmation according to the type of the connection, and after confirming by these checksums, it is sent to the upper layer. RIP database 30 R1 and R2 run RIP ; R2 and R3 establish OSPF neighbor relationships. In the initialization case, there are four entries in the routing table of R2 , as shown in the figure above, and there are only two entries in the routing table of R1 , that is, two direct links. So now,ccnp switch 642-813, we do the re-release action on R2 , and redistribute the OSPF route to RIP , then the configuration is as follows: * i The route to the LOOPBACK interface. R1 RIPv1 All devices in a VLAN are in the same broadcast domain, and different VLANs are different broadcast domains. Set ip next-hop verify-availability 10.2.2.2 20 track 2 Switchport mode private-vlan promiscuous Switchport private-vlan mapping add 100 101 Command Summary Represents a range. Matches only one of the characters contained in the range. LACP mode: We know that in a Layer 2 switching environment, a VLAN is a broadcast domain. Broadcast domains with different VLANs are generally different logical subnets, and they are isolated from each other and cannot communicate with each other. This can isolate broadcasts. effect. However, in actual networks, VLANs often require mutual access. For example, different departments of the same company are divided into different VLANs . If there is data exchange between these departments? Then the Layer 2 switch cannot be implemented, and it needs to use the Layer 3 device.
