Routing entry for 8.8.8.0/24 Redistribution between different OSPF processes This is the problem, how to solve it? Very simple, on the OR2 , deploy PBR , as long as the server data from Netcom, all forced to OR1 , it is solved.

Static routes Solution: Modify the routing protocol management distance 98 Transparent mode VTP configuration revision number is always 0 ? Establish BGP neighbors Vlan 100 RIP Version 2 Protocol Analysis When UDLD detects a unidirectional link failure, it administratively shuts down the interface and prompts the user. Unidirectional links can cause various problems, including spanning-tree topology loops Note that this modification will take effect on all routes sent by R5 (the weight of all routes will become 100 ), and BGP routing table entry for 100.100.100.0/24, version 5 Paths: (2 available, best #1, table Default-IP-Routing-Table) Multipath: eBGP R4#show ip bgp 172.16.0.0 VTP operation Private-vlan primary Neighbor 10.1.23.3 local-as 201 no-prepend replace-as * i At this time, on R4 , only 1.1.1.0/24 and 192.168.13.0/24 can be learned. Ip prefix-list ABC seq 5 permit 172.0.0.0/8 le 24 Lab 3 : The access layer switch is inserted into option82 , and the upstream core switch also turns on dhcp snooping. Configuration view and verification BGP stipulates that routes learned through one IBGP are not propagated to all other IBGP neighbors. This is the horizontal split rule of BGP . !! ISP1 , ISP2 and GW all need to open CDP At 1 o'clock, it can be considered that this address represents a broadcast address or a multicast address in the Ethernet, or represents a broadcast address or a function address in TR and FDDI . The next bit is the G/L bit (also known as U/L, where U is global). When this bit is set to 0 , it represents a global management address. basic concept Standby is 10.1.1.252, priority 100 (expires in 7.572 sec) //The effect is the same as above A match to a start, the end of any single character string, such as A0 , a! Etc. Metric =0 The certificate contains the password information when it is verified using plain text. OUT direction 0 packets, 0 bytes switched through the prefix tmstats: external 0 packets, 0 bytes Show ip bgp on R3 Fa0/20 Address family identifier. When the value is 2 , it indicates the IP protocol. 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 Network 100.0.2.0 mask 255.255.255.0 Vlan 10 CCNP ROUTE contains all the contents of the book *>i10.1.12.0/24 Set ip next-hop recursive FastEthernet1/0 Backup port: Discard status. A backup of a specified port occurs when a switch has two ports connected to the same shared medium. LocPrf Connectionless packet transfer service Because RIP appeared earlier, early routers used serial link interconnection (point-to-point links), so RIP triggered updates only supported on point-to-point links,ccnp route v7, for Frame-Relay and Ethernet. In the multi-access interface, RIP trigger update is not supported , but the Frame-Relay point -to- point sub-interface is considered by RIP to be a point-to-point link, and the trigger update can be enabled.
