Define matching criteria Disable port Circuit-ID suboption fields This command can be used in the following ways: 100 The src-mac detects the received ARP packet. The source MAC address of the Ethernet pillow is the same as the sender MAC address in the ARP body . This verification action is performed in both the ARP request and the response message. The configuration of R5 is as follows: Private VLAN ( PVLAN ) AS Hops 1 Both R1 and R2 inject 100.0.1.0 and 100.0.2.0 into BGP using network . The result found can be understood as a pointer to find the associated outbound interface: If the BGP route is locally originated (network or the redistribute) in , carries the MED to a value EBGP Peer Exist-map Neighbor 5.5.5.5 ebgp-multihop 3 Sourced in sev-epoch 1 Encap length 14 Tag 1111, type extern 2, forward metric 64 When no port-secuirty mac-address sticiky is typed at this time , all sticky secure address entries become dynamic secure address entries ( SecureDynamic ) When the network topology changes, the switch that first recognizes the change will send the TCN ( TYPE field = 0x80 ) from the root port to the upper layer switch (in the direction of the ROOT ) until the root switch, except the upper switch. The upper layer switch sends the TC , and also returns one No-export Peer using Route-map in the case of ) : Once the ORF is deployed ,ccnp route 300-101 book, the BGP peers will negotiate the ORF capability in the open message when the BGP peer relationship is established . If the negotiation succeeds, the ORF content is pushed using the route-refresh packet . R3 associates the route-map with the redistribution of the direct route 3.3.3.3/32 , tag#11 , and the route is passed to R2 . On R2 , the redistribution of RIP to OSPF is deployed. After the external route of 3.3.3.3 is injected into OSPF , the tag value is carried by default. 200 i The Protected port feature cannot be configured across switches: Shows all routes received from the specified neighbor (a subset of the previous command, shown here is the route remaining after the inbound policy is executed) Document number The KEEPALIVE message actually compensates for the defect that TCP cannot confirm the peer's survival. In CEF , there are two main types of load balancing, based on messages and based on purpose. R4 released the RIP route of 100.1.1.0/24 , which can be learned by both ASBRs . The solution is to configure static summary routes on the two ASBRs : Note that the BGP created by R3 uses the AS number of 64512 , which is the federate member AS number instead of the federated AS number. Ip route 0.0.0.0 0.0.0.0 192.168.23.3 Undoubtedly, R3 will preferably OSPF the B route, since OSPF the AD small, so that R3 is formed suboptimal paths, which go B segment will choose R1-R2 -R4-R5 this path. Furthermore, in the routing table of R3 , the route on the B network segment is O , then even if R3 does a re-release from RIP to OSPF , the re-release is definitely a failure, because we have said before, the routing protocol is heavy. The release will only live in the routing table, and the routing table on the B is OSPF , so the re-issue fails.
