Therefore, in fact, the ORF is a feature of the route-filtering by means of the prefix-list . The prefix-list is pushed locally to the peer to allow the peer to perform routing prefix filtering. If there are multiple routes from the same neighboring AS and multiple paths are available through Maximum-paths , all routes with the same cost are added to Loc-RIB. Two modes of operation: normal (the default) and aggressive Route poisoning 1 : Request message, requesting all or part of the routing information from the neighbor; Is 2 , 3 with AS the first comparison, 2 is MED small it is preferable; 2 with a further comparison, one of external routes it is preferably ( MED not compare) 32768 Optional non-delivery Let's analyze that SW1 inserts the DHCP request message from the PC into option82 and then sends it to SW2 . Via SW2 Fast forwarding Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale R3#show ip bgp summary Redistribute ospf 1 Weight On the debug information we found: ARP ACLs take precedence over DHCP snooping database entries. After you specified the global command ip arp inspection filter version 3.3.3.3 ( metric 2 ) from 3.3.3.3 (3.3.3.3) Router os 1 Flooding the MAC table to the above port SW1 and SW2 are configured as VTP mode client ; SW3 is configured as VTP mode Server Bridge ID in the MAC ,ccnp switch 300-115 quick reference pdf, is the backplane of the switch MAC , the port ID in the MAC switch port MAC , all the view switch mac available 100 Router bgp 200 C 1.1.1.0 is directly connected, Loopback0 2.0.0.0/32 is subnetted, 1 subnets Mode 100 i Must be zero The penalty value of all normal routes is 0 , and the penalty value is added instantaneously. If the packets of the same data stream are sent in different paths, the IP packets may need to be re-queued when they reach the destination. This may reduce the forwarding performance of traffic such as VoIP , or if the packets arrive out of order, the quality of service will be degraded, packets may be discarded, and delay jitter will be added. 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.
