Repeat, you can configure multiple Use the clear port-security configured command to clear all manually configured security address entries. Use the clear port-security all command to clear all security address entries. RFC1723 defines an acceptance control switch Match 100 Because ARP 's response does not need arp request is a prerequisite to send directly, so an attacker can construct arp reply message is sent to the target of attack, to refresh the attacker's arp table, to achieve the same arp deceitful purposes. Tunnel Tunnel interface Cluster ID . If the cluster contains multiple RRs , you need to manually configure the cluster ID for each RR . So now, we add the following in the configuration of R2 : Next Hop ! Path not synced, but sync is on If multiple path originating router IDs or router IDs are the same, then the shortest path of the Cluster-List is preferred . These two attributes are used to prevent ringing within the federation and member AS . Name server 200 i Generally, it is 60-240 seconds longer than the invalid timer . If this time also expires, the routing entry is completely deleted. Cisco default 60s (note than invalidtimer multi- 60s ), RFC default 120s VLAN works on the second layer of the OSI reference model The problem is similar to that mentioned above. Both R2 and R3 can learn to update the BGP B network segment route from R4 . Suppose R2 republish do first,ccnp 300-101 ine, then B routes will be injected into the OSPF , the finally R3 learned, then R3 , the same time from the OSPF and IBGP learned this route, will preferably OSPF , since OSPF is AD smaller. As a result, on R3 , the redistribution of IBGP to OSPF fails because the route of the B network segment is not BGP in the routing table . Furthermore, R3 has been re-released in both directions. Therefore , the route of the B network segment will be re-released back to IBGP . Since then, there may be a series of problems such as sub-optimal paths and loops.
