Network 100.0.1.0 mask 255.255.255.0 Preference , will trigger Notifacation message , causing session interruption; but can use IN on AS border router 2 Dialer Dialer interface Manual summary The IP header is 20 bytes, the ICMP header is 8 bytes, and the ICMP data payload is 1472 bytes, which is exactly 1500 bytes. Therefore, on the CISCO IOS device, the size followed by the ping refers to the entire size of the outgoing IP packet. Static route configuration 20 The following figure is the sender using the route-fresh message to push the prefix-list As we R3 on the RIP routes injected into OSPF marked the Tag 1111 , then the next IP protocol number 88 Modify the TAG of all external LSAs generated by the ASBR . Two-way re-release of OSPF and RIP The LP field is all there, but it will assign a default value to this route locally, which is 100 ,ccnp tshoot notes, and then pass it to its own IBGP. 172.16.10.1 , in fact, this IP may be understood as 172.16.0.0/16 within the network, but also in 172.16.10.0/24 within the network, of course, here we can see it, then who is more accurate? It is clear that 172.16.10.0/24 is more accurate, we say that its matching length is longer than 172.16.0.0 . R1(config)# ip prefix-list list1 deny 172.16.32.0/21 R1(config)# ip prefix-list list1 permit 0.0.0.0/0 le 32 R1(config)# route-map test permit 10 Router bgp 100 R1 announces the LOOPBACK network segment in the BGP process If R2 on ip route 1.1.1.0 255.255.255.0 null0 , this time there is no routing table OSPF of 1.1.1.0 routing the unsuccessful thus re-release, so R3 can not learn the 1.1.1.0/24 route; In the above circumvention scheme, we use ACL to match the route directly , and then call it in the distribution list. This method is not scalable. If there are too many routing entries re-advertised into OSPF , the ACL entry will be crazy. So we try to have a method with a more scalable, for example, in R3 on the RIP redistributed into OSPF , when injected into the route marked Tag , then what in R2 when on deployment distribution list, you You can associate a route-map to "crawl" these routes with tags .
