Cisco default 60s (note than invalidtimer multi- 60s ), RFC default 120s Neighbor A router that does not support the route reflector function can act as a single router cluster or as a client The configuration of R4 is as follows: ID . 110 0 ? This property may not be supported, but even if it is not supported, the route containing the property should be accepted and passed 1 : Request message, requesting all or part of the routing information from the neighbor; Path ORF Connection-oriented and reliable data transmission service Route-map nat4 permit 10 Route summary issues to be aware of Match ip address pref 1 set local-preference 200 Router bgp 100 No default Routing Information Protocol Three cups of black tea Ip policy-list as100 permit match as-path 1 5.5.5.5 UDLD mode of operation Id 00:00:54 version R2 's F0/0 port is configured with proxy ARP , 3.3.3.0 network R2 itself is reachable, so R2 will respond to this ARP request with its own F0/0 port MAC .

When republishing to other protocols, RIP routes simply compare the tokens assigned to them without comparing the entire route. Let's look at the following example: Local updater ID is 0.0.0.0 (no valid interface found) RIP also supports tags , but it must be version 2 . 100 At this time , the policy is used for R4 on R1 , and the route AS_PATH of 10.0 is inserted into the AS number of 100 100 , and R5 is preferably R3 . Why on R5 will select R3 , through experimental results, where R5 received two routes, one from the Federal EBGP neighbors, one from EBGP neighbors, the final preferred EBGP routing neighbors. We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows Gateway of last resort is 172.16.12.1 to network 192.168.1.0 Note that community is not sent by default and must be send-community . *Mar 1 00:11:47.887: ICMP: redirect rcvd from 192.168.123.1- for 2.2.2.2 use gw 192.168.123.2 2 10.1.23.2 Configuring Example 6 Deploying Distribution Lists When Republishing Between Protocols Each group of GLBPs can have up to four member routers as ip default gateways. These gateways are called AVF ( active virtual forwarder ). The cost value is increased, so that the OSPF metric of R4 going to 3.3.3.3 route becomes larger. What happens? Must be zero On this topic, the individual feels that there is no need to study it. It does not make much sense for the research of class-based routing protocols. No matter the actual application or the LAB exam, it is no longer involved,ccnp route dumps 9tut, and you are interested in making it yourself. The disadvantage is that the original Ethernet frame is destroyed and the FCS is recalculated . ISL is the direct encapsulation header and trailer. DOT1q public, ISL private The BGP election routeriID rule is the same as OSPF . The distribution list is deployed in a link state routing protocol such as OSPF . If the out direction is to be used, it can only be used in such a situation. The behavior of the router is hop-by-hop. Each router along the path to the destination network must have a route to the destination. Neighbor 1.1.1.1 remote-as 123 summary: Router(config-router)# distance eigrp internal-distance external-distance Limit of inhibition: 2000 When a route oscillates (continuously fails, recovers), it is assigned a penalty value. The more the swing, the larger the penalty value and the constant accumulation. The default COST value of all ports on the switch will increase by 3000 , so that the port of the switch is not elected as the designated port. Configuration example 46 verification Router(config-dhcp)#network [network address][subnet mask] Note that at this time, the routing table is used to recursively find the route to 10.1.12.2 , so there must be reachable routes in the routing table. !! GW has no other configuration about routing Redistribute rip subnets route-map test 100 The third column is empty or i . If it is empty, the route is obtained from the EBGP neighbor. The i indicates that this is the route learned from IBGP . The last column indicates the origin of the BGP routing information. DMZ-Link Bw 193 kbytes is an extended community attribute, so if you want to pass this value to the just IBGP neighbor in the AS , you need to add send-community and add the extended keyword. The following is the change of the packet after MD5 authentication is configured (all TCP packets have MD5 HASH field added): Situation 3 10.1.25.2 Knowledge review //The default community is not sent, so this command must be configured 1 network entries using 117 bytes of memory 1 path entries using 52 bytes of memory 8.1 Overview 91 The configuration of R2 is as follows: Look at the above picture, the gray space 172.16.0.0/16 , this network number, we call the main class network number , the so-called main class network number, meaning the network number, according to the IP address category to which it belongs , corresponding to The network number obtained after the default subnet mask length. Such as 172.16.0.0 this is a Atomic_Aggregate is a recognized self-determination attribute; Aggregator is optional. Scp: Database agent URL R4#sh ip bgp We found that although R4 learned these two prefixes through BGP , it is also valid (with * ), but it is not optimized (not best , no > mark). If it is not optimized, it will not be loaded into the routing table. Then why is this? Note that the next hop of the two routes is 10.1.13.1 , and it is worth noting that the directly connected network segment of 10.1.13.0 is not declared into OSPF by R3 . In other words, R4 goes to the next-hop of the two routes. Unreachable, the next hop is unreachable. Therefore, although the two BGP routes are in the BGP table, they are not best and cannot be loaded into the routing table.
