Ip dhcp relay information trust-all If you only want to detect the reachability of some next-hop devices, you can configure different route-map serial numbers to selectively use this feature (in the same route-map ). Regular updates, broadcast updates, routing table updates; according to rumors; distance vector routing protocols do not understand network topology STP port state transition process After SW3 receives this message, it knows that SW2 no longer has vlan10 users, and no longer needs vlan10 traffic, so it will trim vlan10 on its own FA0/22 port : Virtual-PPP Virtual PPP interface Virtual-Template Virtual Template interface Update behavior The distribution list is deployed in a link state routing protocol such as OSPF . If the out direction is to be used, it can only be used in such a situation. BGP federation Local-Preference 2 state changes, last state change 00:07:34 Virtual IP address is 10.1.1.254 Router bgp 300 Tftp: Database agent URL 200 i In this way, the summary route inherits the detailed AS_PATH attribute, so atomic_aggregate is redundant. Therefore, in the above case, the generated summary route does not carry atomic_aggregate . Let's see: Route-map The WEIGHT attribute is a CISCO private attribute. The scope is this router (not passed), the value is not included in the update Preferably the BGP NEXT_HOP nearest route 10.1.12.2 Is 2 , 3 with AS the first comparison, 2 is MED small it is preferable; 2 with a further comparison, since the opening of the always-compare-med Http: Database agent URL Write-delay Configure delay timer for writes to URL Experiment 3 BGP CISCO Note: The DHCP option-82 feature is supported only when DHCP snooping is globally enabled and on the VLANs to which subscriber devices using this feature are assigned. Switch(config)# vlan 255 Switch(config)# interface fast0/15 Switch(config-if)# switchport mode trunk Switch(config)# interface vlan 10 RIPV1 operational behavior 32 When a data frame is sent from the Access port, the switch strips the VLAN tag of the frame and then sends it out. Different prefixes (network number + mask, indispensable), belonging to different routes in the routing table By default all routes belong to this community DHCP Snooping Binding Database Network 10.1.45.0 0.0.0.255 area 0 Weight ? ? ? Let's take a look at R4. SW1 (config-if) # glbp 1 priority 120 !! Priority defaults 100 , the highest priority becomes the AVG , under equal priority, the maximum IP interface becomes the AVG . Default " AVG preemption" is off Blocking to forwarding state usually takes 30-50s (default 50S , ie 20+15+15 ), this time can also be adjusted by configuring the spanning tree timer. Passive interface IP protocol number 89 description The redistribute local route learned from the IGP routing protocol enters BGP , and the MED value inherits the metric in the IGP protocol. // AS200 is the Primary AS and is used to configure the BGP process. DTP *> 172.16.0.0 The comparison principle mainly refers to the local use of different methods such as network or redistribute when entering an IGP route into the BGP table. OSPF Revision statement Cisco Private Hardware address Sw1(config-if-range)#channel-protocol pagp/lacp Sw1(config-if-range)#channel-group 1 mode desirable Port-Security Overview For the next hop and route tag, see Volume I, page 189 . Will be reflected to other clients, non-clients and EBGP neighbors. If the currently configured keepalive timer is greater than min ( holdtime ) /3 , then int[min ( holdtime ) /3] Note that PEs in an MPLS VPN environment do not have this limitation. Technical analysis: Tunnel Tunnel interface length Switch(config)# spanning-tree [ vlan vlan-id ] hello-time sec Switch(config)# spanning-tree [ vlan vlan-id ] forward-time sec Switch(config)# spanning-tree [ vlan vlan-id ] Max-age sec MED Ip route 0.0.0.0 0.0.0.0 serial s0/2 The dst-mac detects the received destination ARP packet. The destination MAC address of the Ethernet frame header is the same as the target MAC address in the ARP body . This check is for ARP response . When this option is enabled , ARP packets are discarded if the two MAC addresses are inconsistent. Interface vlan 10 MED : 100 This global configuration command creates a route-map that uses a custom string to represent this route-map . You can do this in a Ip address 192.168.100.254 255.255.255.0 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale Passive: passively wait for other side to ask basic concept 100 i 100 RFC1724 After the trigger update is enabled, the routers at both ends of the link no longer send routing updates periodically. Of course, another problem arises. If the route in the routing table expires, it will hang, so it is necessary to trigger the update. It must be configured on both interfaces of the link, so that the routing update will be marked permanent for permanent. Length of the circuit-ID type Network 100.0.2.0 mask 255.255.255.0 Root port: The interface that receives the optimal BPDU is the root port. This is the closest ( cost minimum) interface to Root . Associate the static route of the next hop Ip address 192.168.100.1 255.255.255.0 Index Decision making Command summary 81 Set ip next-hop ip1 ip2 ip3 ,ccnp route exam how many questions, this knowledge point is no problem, right? After the match is live, the packet is first sent to the first next-hop ip address . If the direct connection associated with the ip address is DOWN , then the next next-hop ip address is switched , so next-hop .
