As a result, on R2 , the OSPF route 1.1.1.0 in the routing table and the 192.168.12.0 directly connected network segment that is declared into the OSPF process are all announced to RIP ,ccnp switch dumps 2019 pdf, and R1 can learn the two routes through RIP. , as shown in the red bold part below. Maximum route entry 3.3.3.3 Rule validation ( AS_SET type AS_PATH , i.e. {} in the AS number in AS_PATH when calculated as a hop) Vtp pruning can only be turned on in server mode * i Interface loopback1 Experimental example: Called when republishing BGP table version is 4, local router ID is 4.4.4.4 As a result, on R4 , the BGP table is as follows: Next-hop , the next-hop is changed to the update source IP of R3 , which is the loopback interface IP. Rcp: Database agent URL Roo also received the request, and the request it received from the network segment 172.16.20.0 , and the table found that the network that the route to the host Milne is located ( 172.16.21.0 ) is different from the network that received the arp request packet. And the interface opens the arp proxy, so reply to its own interface mac. Route Control Overview 77 Note that atomic_aggregate is a recognized free decision attribute. Let's understand: ? If the aggregate-address does not contain any keywords, the details are also passed, and the summary route is also passed. Hardware address C 10.1.12.0 is directly connected, Serial0/0 AS does not compare the MED values. In other words, for multiple paths, the MED is compared only if the first AS in AS_SEQUENCE is the same ; any leading AS_CONFED_SEQUENCE will be ignored. MED only affects traffic between directly connected autonomous systems, and does not pass across ASs. Access-list 1 permit 1.1.1.0 Do the following configuration on R2 and test it ( all tested in no ip classless and closed ip cef environment ): R3 and R4 , R4 and R5 establish IBGP neighbor relationships, and R3 R4 R5 uses LOOPBACK as the update source and refers to the neighbor . 5.5.5.5 ( metric 2 ) from 5.5.5.5 (5.5.5.5) Ip arp inspection filter arp_acl_name vlan {vlan_ID | vlan_range} [static] Includes 7 -byte preamble (a string of 1 , 0 intervals for signal synchronization) and a 1 -byte frame start delimiter ( 10101011 ) Set ip next-hop recursive 10.1.12.2 In addition, if the command is configured when writing: Configure a static default route locally, such as ip route 0.0.0.0 0.0.0.0 null0 Abc+d Network Layer Reachable Information ( NLRI ) One or more (length, prefix) binary groups used to advertise IP address prefixes and prefix lengths We spotted FIG, R1 and R2 between runs RIP to exchange routing information, R2 by RIP learned the R1 release over 192.168.1.0/24 and 2.0 / 24 routing information loaded into the routing table, labeled R & lt . While R2 and R3 and running OSPF , establish OSPF adjacency, R2 also from R3 , by OSPF learned the two routes: 3.0 and 4.0 / 24 , is also loaded into the routing table, labeled O . So, for R2 , it has its own route to the whole network, but inside R2 , we can understand this : it will not change the route learned from RIP .The OSPF route is told to R3 , and the route learned from OSPF is not sent to R1 as a RIP route . For R2 , although there is complete routing information in its own routing table, it is as if there is a gap between the entries of R and O , which cannot be exceeded.
