The smaller the MED, the higher the priority 345 ; R3 has a federated IBGP neighbor R4 . The difference between set ip next-hop and set ip default next-hop is relatively simple, it is not resolved here. VTP Version capable Match tag matches based on the tag of the route Is 6 , then the type is 802 , default ethernet FastEthernet0/0 If multiple path originating router IDs or router IDs are the same, then the shortest path of the Cluster-List is preferred .

When both the primary and secondary addresses are present, the RIPV1 router will use the mask of the secondary address of the interface that receives the route update packet locally (this has been verified in the above experiment). Next Hop Mismatch. This method requires that the community contains 100:11 and no-advertise to match. Set extcommunity cost pre-bestpath 1 10 For the original attribute, it specifies the source of the route update, which has the following values: Origin IGP, metric 0, localpref 100, valid, internal Local ACL There are class, classless routing protocol redistribute Port-Security violation penalties Protocol Interface The TAG value is set when the originating ASBR generates an external LSA . If the external LSA is re-advertised to other OSPF autonomous systems, the TAG value is carried by default.

Next Hop LACP mode: Dialer Dialer interface Under normal circumstances, the data is preferred to go ip next-hop , that is, go ISP2 Metric =0 Violation Mode : Shutdown !! After the violation, the default is shutdown Aging Time : 0 mins The NEXT_HOP summary route is 0.0.0.0 (because the summary route is generated locally) Topology change mechanism (delivery) Solution: Use distribution lists to avoid the sub-optimal routing problem AS_PATH , and AS_PATH only when routing out this AS or BGP routers to update EBGP will change when neighbors in AS inside will not change, therefore, in the AS internal, anti-ring requires the use of split horizon. So how to solve the problem that R5 ca n't learn routing? Local origin 100 Of course, this time 1.1.1.0 is unable to access 3.3.3.0 , because R3 does not have a route in the RIP routing domain (that is, there is a problem with the backhaul routing, data communication must always consider the round-trip path, remember), so if To achieve network-wide interworking, you need to be on R2 : Revoked route AS_Sequence is well understood. In the case where the above figure does not make any policy, the type of AS_PATH carried by the BGP route delivered to R4 is AS_Sequence . This is an ordered list of AS numbers. When R4 receives the route update, AS_PATH is 300,100 , OSPF and BGP LocPrf Of course, the link type of the interface can be modified by commands. In interface mode: spanning-tree link-type ? Supported for switch ports and routed ports Go ahead and assign the interface of SW1 and SW2 to the PC to vlan10. Neighbor 1.1.23.2 route-map test out Router# sh ip bgp summary Network 10.1.25.0 0.0.0.255 area 0 The first 8 bits of the route must match the first 8 bits of 172.0.0.0 , the other bits are not concerned, and the mask must be /8 . Fa0/20 1-4094 BGP table on R4 : Network Layer Reachable Information ( NLRI ) One or more (length, prefix) binary groups used to advertise IP address prefixes and prefix lengths If the router accepts the parameters of the neighbor in the OPEN message, it will answer a keeplive message, and send the message for the period of 1/3 of the holdtime (but not less than 1S ). CISCO defaults to 60S . If the hold time is 0 after negotiation , the keepalive keep-alive message is not sent . Origin IGP, metric 0, localpref 100, valid, external, multipath, best 1.1.1.1 (metric 129) from 4.4.4.4 (4.4.4.4) STP port status Neighbor 5.5.5.5 weight 100 Received a Layer 2 frame. 10.10.10.0/24 Weight R2 RIPv2 Of course, the link type of the interface can be modified by commands. In interface mode: spanning-tree link-type ? Neighbor 3.3.3.3 remote-as 345 AS_SEQENCE : an ordered list of AS numbers Switch(config)# vlan 20 9 AAAA03 SNAP (fixed value) Because Layer 3 switches support so many types of interfaces, the deployment of Layer 3 switching networks is more flexible and scalable. Network, which is consistent with topology expectations, but the underlying cause is still due to the learning of R2 compared to IBGP routes from R3 . Passive-interface configuration 51 Interface fast0/0 Recognized self-determination Route tag TAG ( to be revised ) Active is 10.1.1.252 (primary), weighting 100 (expires in 7.028 sec) Arp replies sent: 1 The configuration commands are as follows: 16/32 bit Set ip next-hop 22.2.2.2 A policy-list is like a route-map that only contains a match statement. When a local BGP route is advertised to an IBGP peer , the MED value must be carried . Note that the above is the default metric when re-publishing from other dynamic routing protocols into this routing protocol . If you republish a local direct connection or a static route, the situation changes, as follows: Block the interface of SW3 . Discard (that is , the combination of disabling, blocking, and listening in 802.1D ) Improve // The offset value is increased by the value displayed in the normal route entry. It is added on the original basis instead of replacing the original hop count. Determine if the frame has a VLAN tag . If R1 turns on auto-summary and network 10.0.0.0 , the subnet will be automatically summarized to R2. 1,10,ccnp switch pdf 300-115,20,30 OpenConfirm Neighbor 10.1.23.2 remote-as 200 neighbor 10.1.23.2 route-map test in Neighbor 3.3.3.3 route-reflector-client 8 bits Modify the TAG of all external LSAs generated by the ASBR . By default, only the MED values of BGP routes from the same neighbor AS are compared , that is, if the two routes of the same destination are from different ASs , the MED value comparison is not performed . MED only affects the traffic between directly connected autonomous systems, and does not pass through the AS . The smaller the MED, the higher the priority. 100 s> 172.16.2.0/24 In PVST+ , a VLAN has a spanning tree. On each switch, a unique identifier is required for each spanning tree, that is, the network. Desirable: capita ask if the other side can/will Configure an interface as a passive interface: Active As a result , the BGP table of R5 becomes as follows: Note that after the DHCP snooping is enabled on the switch , the dhcp packets are snooped. Therefore, when the DHCP attack is generated on the network, the performance of the switch will be seriously degraded. Therefore, you can limit the number of interfaces that can be received on the interface. Number of DHCP packets. Configure the number of DHCP packets per second that an interface can receive. The range is 1 to 2048.
