However, if the R1 release carry on a tag external routes, and R2 re-released on OSPF into RIP , tag lost: None Multilink Multilink-group interface ? The federated AS number in AS_PATH is used to avoid loops within the federation 14 Next hop 10.1.12.2, FastEthernet0/0 valid adjacency R3 's loopback interface IP has been declared into OSPF , and R4 learns loopback routing through OSPF . Therefore, the BGP table for R4 is as follows: ? None Protocol overview At the same time in the out direction, there is no problem. Can be configured in global mode or in interface mode, the difference is as follows: global configuration: spanning-tree portfast bpdufilter default A single RR may have a single point of failure problem, so from the perspective of redundancy, there can be multiple RRs in a cluster , Client and each Scanning messages on the intranet. The destination addresses of these packets are some unknown addresses that start with 192.168 , or even addresses that do not exist at all. The packet is sent to the gateway, which is the Layer 3 switch. Since the Layer 3 switch is configured with the default route,ccnp switch 802.1x, these packet destinations are matched by the default route and directed to the egress router, and the summary route is deployed on the egress router. Although the destination address of the packet does not exist in the internal network, it is an IP in the summary route , so it is forwarded back to the Layer 3 switch by the egress router. Then the Layer 3 switch forwards the packet according to the default route. Back to the router, this forms a loop of data.
