ccnp route 6.0

When R2 is configured with no validate-update-source , R2 will not verify the RIP update message source, so R2 will accept R1. 8 LP takes the maximum value of LP in the detailed routing You can also configure DAI to discard the Ethernet frame source MAC and ARP body in the MAC illegal inconsistent ARP . This is followed by a further introduction. If a path satisfies any of the following conditions, it is not a valid candidate in the optimal path selection process. Neighbor 10.1.13.3 remote-as 345 Enable the routing function of the Layer 3 switch. Classification of path attributes: Set tag 20 3.3 802.1D Aging Type : Absolute SecureStatic Address Aging : Disabled The set command above is used to define the detail route to be injected into the local BGP RIB . The injected prefix can be used Switch(config-if)# switchport access vlan 10 Relevant points * i100.0.2.0/24 None *Mar 1 00:11:48.043: ICMP: echo reply rcvd, src 2.2.2.2, dst 192.168.123.3 Management VLAN in a Layer 3 switch environment BGP stipulates that routes learned through one IBGP are not propagated to all other IBGP neighbors. This is the horizontal split rule of BGP . Sw1(config-if-range)#switchport trunk encapsulation dot1q R* 0.0.0.0/0 [120/1] via 192.168.12.1, 00:00:03, Serial0/0 Deployment Highlights 63 CASE1 : Optional non-delivery, generally used between AS to affect routing. Route-map nat3 permit 10 match ip address 2 match interface serial0/1 Then the received route becomes 10.1.20.0/24 and the mask is correct . The current Ethernet implementation is such a service. 3.3.3.3 In general, a Layer 3 switch contains two types of ports: Layer 2 interface L2 and Layer 3 interface L3. R3 , R4 , and R5 run OSPF , announcing the three interconnect interfaces and their respective LOOPBACKs. Network [Case] ​​routing flipping Different prefixes (network number + mask, indispensable), belonging to different routes in the routing table About PBR 80 For 802.1D ,ccnp route 6.0, when a port is elected as the designated interface, which from blocking to forwarding at least 30S of time. However, in RSTP , the proposal/Agreement mechanism enables the interface to complete a fast, reliable transition in seconds. The basic interaction process is as follows (the process described below is independent of the above diagram): Switchport access vlan 10 interface fast0/24 The standard ACL active part and destination part use the source matching route prefix and use the destination part matching route mask. Can not contain R1 RIPv1 BGP table version is 10, local router ID is 2.2.2.2 A strange phenomenon has appeared. It seems that R4 does not reflect the route from R5 to R3 . Why? In theory, the RR will learn from non- client of IBGP neighbor to route reflection to their Client , but it is clear, in this experiment, R4 and did not learn from R5 route reflection to their Client . Match ip address 2 Policy deployment in BGP When a local BGP route is advertised to an IBGP peer , the MED value must be carried . Switch(config-if)# switchport mode trunk Switch(config)# interface vlan 255 Default behavior: source IP address pair ( src-dst-ip ) On R2 , in order to reach the network connected by R1 , R2 configures a tool that uses route summarization, referring to a summary route: 192.168.0.0/16 to R1 , although this does serve the purpose of network optimization, but this summary route Too "rough", it even includes the network segment on the R3 side, we call this behavior not accurate enough. Therefore, an ideal way is to use a "just right" summary route that includes these detailed routes, so that you can avoid the problem of insufficient aggregation.
