ccnp route preparation

The ORF feature is very simple, that is, R2 pushes this list to R1 , so that this strategy performs filtering on the R1 side, as shown below. The LP attribute of the route is preserved throughout the federation If the ibgp keyword is not associated , only EBGP routes will be equivalently load balanced (by default only for EBGP routes). If maximum-paths is not configured , the next routing principle will be followed. Except none The destination IP address of the route , which can be the address of the natural network segment or the subnet address or R5#show ip bgp 11.11.11.0 Ip rip trigger Portfast Ip prefix-list 1 permit 11.11.11.0/24 route-map test deny 10 During the migration, the router running DUAL AS can establish EBGP with the external AS using both the primary AS and the secondary AS. 3 : MD5 verification. parameter Flag: 0x860 Field name Only vlan1 and vlan10 In order to enable the ARP message sent by PC2 to be released, we first use the method of manually configuring the DHCP snooping bingding entry: Access-list 2 permit 192.168.2.0 0.0.0.255 route-map PBR permit 10 First of all,ccnp route preparation, the route-map is a very important tool, and it is used in a wide range. When defining a route-map , we use the route-map keyword to associate a custom parameter, such as test . A route-map list by the test string unified representation, you may be in one route-map define a plurality of sequences, a sequence number to a decimal representation, such as the figure above, 10 , R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. 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 . The configuration of R1 is as follows: The configuration of R2 is added as follows: Create a secondary VLAN : 8 bits BGP routing table entry for 100.0.1.0/24, version 3 The above four types are distinguished by the type code in the AS_PATH attribute. For the two federally unique AS_PATH types, please refer to the “Federal” section of this document for details. How do you understand the first two AS_PATHs ? !! Match, go this one Routing, then: ?

Let us first consider the case of 802.1D . When the link between Root and B fails, since the interface connected to B on C is BLOCK , it does not send BPDU to B. Therefore, B considers itself to be Root at this moment , so it goes to C. Send yourself a BPDU for Root . Because at this time , the interface of C also stores the BPDU sent by B to the previous B , and this BPDU is compared with the BPDU sent by B to B.It is better, so C ignores these suboptimal BPDUs directly . Until the Max-Age timeout, the BPDUs sent by the previous B stored on the interface of C will be aged. At this time, the interface enters LST and starts to send BPDUs , indicating that the root is Root. . At this point, B accepts the facts and sets the interface that connects itself to C as the root port.
