Tag information set local tag: 100 Advantages and disadvantages Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale Configuration example Alternate port: Discard status. In addition to the root port and other ports to the root path, if the active root port fails,ccnp route dumps vce, the replacement port becomes the root port, so the alternate port can be understood as an alternative to the root port. 100 Router bgp 345 Bgp fast-external-fallover 30.30.30.0/24 Neighbor 4.4.4.4 update-source Loopback0 The configuration of R2 is as follows: table of Contents The AVG is responsible for responding to the ARP request of the PC to the gateway , while the AVG is responsible for the allocation of the virtual MAC . AVG can be flexible depending on the load balancing mode PC 's ARP request response. The KEEPALIVE message actually compensates for the defect that TCP cannot confirm the peer's survival. Address family identifier. When the value is 2 , it indicates the IP protocol. 2 : RIP-2 ; R1 , R2 , and R3 run RIP and only announce the direct link between the three. In R1 the ip default-network 172.16.0.0 SW2(config)# interface vlan 10 ? Maximum MAC Addresses : 1 !! The maximum number of secure addresses, the default is 1 At this time, R2ping 1.1.1.1 will pass (equivalent to 172.16.12.1 as the last hop help object) Inter- VLAN routing Includes 7 -byte preamble (a string of 1 , 0 intervals for signal synchronization) and a 1 -byte frame start delimiter ( 10101011 ) Cisco Private Neighbor 4.4.4.4 update-source Loopback0 neighbor 10.1.25.2 remote-as 200 Activate a particular VLAN 's STP , To close the STP , plus no BGP is designed to AS transfer routes between, so it is actually a hop AS . Re-routing release ( Redistributing Routing Protocols ) Next Hop This global configuration command enables PBR to take effect on locally originated traffic. Private-vlan mapping add 101,102 BGP metric is set to IGP metric Flag: 0x860 The Protected port feature cannot be configured across switches: Aggregate-address 172.16.0.0 255.255.0.0 as-set summary-only Path The maximum survival period in the discard BPDU before the bridge used to store BPDU time default 20S . If consecutive receive 10 th bpdu 16/32 bit A sends a data frame to B requesting to establish a reliable connection-oriented connection. Where min ( holdtime ) is the minimum value of holdtime between two BGP neighbors. Route-map 55 Dialer Dialer interface 802.1W Native vlan R1(config-router)#distribute-list 1 in ? // All interfaces Lease expiration CISCO IOS 12.1 began to fully support dynamic soft reconfiguration of inbound routes. This soft reset method sends route-refresh messages directly to specific neighbors locally . ---------- Ip address 192.168.100.254 255.255.255.0 Match as-path 1 Manually modify the hop count of RIP . First configure matching routes 3.3.3.3 basic concept Encapsulation protocol Set next-hop specifies the address of the next hop , specifying the next hop of BGP . When a data frame is sent from the Access port, the switch strips the VLAN tag of the frame and then sends it out. The penalty value of all normal routes is 0 , and the penalty value is added instantaneously. Add the following configuration on R5 : In B and C on a pair of A do strategy, i.e. AS external boundary of AS do MED , such that A selected lower the MED value. The KEEPALIVE message actually compensates for the defect that TCP cannot confirm the peer's survival. Scanning messages on the intranet. The destination addresses of these packets are some unknown addresses that start with 192.168 , or even addresses that do not exist at all. The packet is sent to the gateway, which is the Layer 3 switch. Since the Layer 3 switch is configured with the default route, these packet destinations are matched by the default route and directed to the egress router, and the summary route is deployed on the egress router. Although the destination address of the packet does not exist in the internal network, it is an IP in the summary route , so it is forwarded back to the Layer 3 switch by the egress router. Then the Layer 3 switch forwards the packet according to the default route. Back to the router, this forms a loop of data.
