^100$ * i Distribute-list route-map test in Path attribute 1 Router(config-router)# distance AD ip-src wildmask acls CDMA-Ix CDMA Ix interface Not advertised to any peer Therefore: the route is redistributed into OSPF , the automatically inherit these external routes BGP 's A_PATH property, note that only inherit AS_PATH ^100_ Private VLAN ( PVLAN ) Metric Can not contain Longest matching principle Interface vlan 10 During the above events, the contents of the following fields will not change: Revision date BPDU format and operation B is RR , C and D are clients , BCD constitutes a route reflection cluster; a BGP route is advertised from C. The configuration of R3 is as follows: If the route is passed from an IBGP neighbor and is introduced by the BGP router in the AS Conduct a three-layer forwarding decision. The CEF table maintains core information extracted from the routing table, which is used to perform forwarding decisions on received messages, including IP prefixes, recursive next hop addresses, and outbound interfaces. An important feature of the CEF table is its ability to make immediate decisions about recursive prefixes. Can only be passed between IBGP peers (unless a policy is made, the LP value will not be lost between IBGP neighbors within the AS ), not in EBGP BGP route advertisement When port-security mac-address sticky is activated on the interface , then: Lead ( PreambIe ) Host 192.168.1.111 255.255.255.0 ... 2.2.2.2 [110/65] via 10.1.23.2, 00:06:40, Serial0/0 Next Hop Three-layer bundle Three-layer exchange Use CDP to detect next-hop IP reachability in PBR environment (without optional parameters) ARP response packets can be sent directly without a request, which leaves a huge loophole for the attacker. Y AS_CONFED_SET A list of unordered AS numbers on a path to a specific destination , using the method with AS_SET Associate route-map when route is republished (typical case) 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 . Range character example: Experimental phenomena: Switchport Sw(config)#vlan 202 Ip as-path access-list 1 permit _1$ It can only be mapped to the ethernet of vlan If the penalty value exceeds the pre-set threshold - the suppression limit: the penalty value reaches this threshold, the route is suppressed, ie not released, until the N half-life, the penalty value is reduced to another threshold: re-use threshold (de-suppression threshold) ), the suppression of the route is lifted. Double-point bidirectional routing re-issuing problems 92 The interface will only receive updates, no updates will be sent. Fast switching is superior to process switching,ccnp switch certification, it uses a route cache ( route cache ) for storing information about a stream of data (Flow) specific information , A very simple method, assuming R3 on the R3 , the first RIP to OSPF route re-release, as already mentioned, a direct problem is on R2 , due to the 192.168.1.0/24 route, and from OSPF and RIP learned, and OSPF the AD value is small, thereby resulting in sub-optimal path, so in order to circumvent this problem, we can directly in R2 deployment on the distribution list, so that the OSPF routing is not loaded into the routing table, in order to avoid suboptimal Path problem.
