STP cost to the root bridge Identify the type of message: 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 . In VTP server mode of SW3 is turned on VTP pruning after, Client of SW1 and SW2 are learning and also to open their VTP pruning . None BPDU , then he will send again. Therefore, for 802.1D , the root bridge will send BPDUs to all interfaces continuously . The non-root bridge will receive BPDUs from its own root port and send BPDUs to its designated port . Non-designated ports will not send. BPDU 's will only listen. Neighbor 10.1.23.3 local-as 201 no-prepend replace-as The switch forwards the DHCP packets carrying the Option 82 information to the DHCP server. The traditional STP , which is 802.1D , is that all VLANs share a spanning tree. The advantage of this is that the switch does not use too much resources to calculate multiple spanning trees. However, the defect is that the port is fixed through the block . As a result, traffic on the network only goes to one side, and some links have no traffic at all, which wastes bandwidth. Optional attribute 10.1.25.2 SW1(config-if)# glbp 1 10.1.1.254 SW2 puts the server into the same VLAN as the PC , which is equivalent to pure pass-through. First, in order to avoid the suboptimal path problem, we use the distribution list in the in direction on R2 and R3 to filter out 1.1.1.0 . 2 : Clear text verification; Total number of bindings: 1 A strange phenomenon has appeared. It seems that R4 does not reflect the route from R5 to R3 . Why? In theory,ccnp route test, the RR will learn from non- client of IBGP neighbor to route reflection to their Client , but it is clear, in this experiment, R4 and did not learn from R5 route reflection to their Client . Retaining the NEXT_HOP attribute outside the federation within the federation CAM is the table that the switch checks when it is used for Layer 2 switching. Show ip bgp route prefix Network It is recognized that the attribute must be followed to describe the next hop router to the destination. Set the security address aging time to 50 min . Valid for secure addresses consisting of dynamically learned MACs Use the global configuration command: err-disable recovery psecure-violation Configuration Revision 15 / / This is used to delete the no-export attribute, is a list of commands 1,10,20,30 Switch(config-if)# switchport access vlan 10 Tag rewrite with Fa1/0, 10.1.13.3, tags imposed: {} via 10.1.12.2, FastEthernet0/0, 0 dependencies Interface f0/2 Neighbor 5.5.5.5 update-source Loopback0 version e Interface fast0/1 S0 192.168.12.1/24 r1 *>i10.1.12.0/24 OpenSent R2(config-router)# distribute-list 1 in fa0/0 Routing feedback 42 Adjacency table 1.1.1.1 (metric 65) from 1.1.1.1 (1.1.1.1) Priority 120 (configured) When we set the number of MAC addresses allowed on the interface to 1 and set a secure address for the interface, then this interface will only be for that MAC. PAgP is a Cisco propretary protocol LACP is IEEE 802.3ad standard So to rule 12 : if multiple path originating router IDs or router IDs are the same, then the shortest path of the Cluster-List is preferred . Address Router bgp 100 Forwarding delay 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 . Redistribute ospf 1 match nssa-external 1 nssa-external 2 CASE2 : R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. Authentication is identified by setting the address family ID field to all 1s ( 0xFFFF ). About UDLD 10.1.25.2 ? [abcd] When the switch receives suboptimal BPDUs from other designated switches or root bridges , 802.1D encounters this situation by first ignoring these suboptimal BPDUs . R1 update source IP match, although the update source of R2 configuration is the default (packet outbound interface IP 10.1.12.2 ), but the BGP connection establishment between the two is no problem, because the connection of R1 to R2 is no problem. . At the same time, it is also possible to delve into the routing problem. For example, if R2 is localized to the 1.1.1.0 static route and is configured as the default route, we will find that the BGP connection can still be established, because R2 is the passive of the BGP connection in this example. who, R1 have specific routes to initiate connection. However, if the static static route from R1 to 2.2.2.0 is changed to the default, then it will not work, and R1 will consider " no route to peer ".
