If deterministic-med is turned on, the information of the route prefix is regrouped by AS. Method 1: Static default route network However, if the R1 release carry on a tag external routes, and R2 re-released on OSPF into RIP , tag lost: 100 i Sourced in sev-epoch 1 Encap length 14 Ip dhcp snooping trust 1 command) only sends and receives v1 messages, v2 only sends and receives v2 messages by default . ? Enhanced Interior Gateway Routing Protocol (EIGRP) ISO IS-IS switchport trunk encapsulation dot1q switchport mode trunk Management adjustments //The details are not released. Match ip address prefix-list Dhcp-snooping Encapsulate the ISL header and the new FCS on the basis of the original data frame Atomic character However, we found that R4 did not pass these two routes to R5 , which is because of the effect of IBGP 's horizontal splitting principle. According to the IBGP split horizon principle, a BGP router, if it learns BGP routes from its IBGP neighbors , will not be able to pass these BGP routes to other IBGP neighbors. The reason for setting this rule is that BGP anti-ring needs to resort to Path Configuration example: Neighbor R3 filter-list 1 weight 4000 Retaining the NEXT_HOP attribute outside the federation within the federation RIP 1 : RIP-1 ; Prefix-list Set the interface to DTP dynamic negotiation, optional auto or desirable STP port status Neighbor 10.1.23.2 remote-as 200 R5 performs link redundancy. However, at this moment, R5 can only go to the target network through R2 . Ip sla monitor schedule 1 life forever start-time now 1,10,20,30 Router ospf 1 Interface fast0/0 ( assigned by the IEEE ), when this bit is 1 , it represents a locally local address in management (as in DECnet ). Ethernet always uses globally unique addresses. 0 , regarded as infinity 0xFFFF IGRP Match x1 match x2 , x3 set Y So looking at the above picture, two VLANs are created on the Layer 3 switch : 10 and 20 , and the addresses of the SVIs of the two VLANs are assigned as the user gateways of the respective VLANs , so that the routing table of the switch is There are routes for two VLAN segments. Then, when the two VLANs need to communicate with each other,cisco ccnp switch guide, the user of VLAN 10 will drop the data to his own gateway, that is , the SVI of VLAN 10. After the data arrives at SVI10 , the Layer 3 switch looks up the table and finds that the destination is the network segment where VLAN 20 is located. Throw the data out of VLAN 20 and eventually reach the destination VLAN 20 of the PC .
